Support Forum » First Timer - Stuck when attempting to load initialload program

May 04, 2009

Hey! New guy here, and I'm having a blast getting into microcontrollers for the first time. As a long time business programmer, it's really fun to get closer to the metal and start to understand how all this technology works at the silicon level.

Anyway, I breezed through the initial build, got the pre-loaded happy message just fine. Installed the USB-to-Serial driver just fine, identified the COM port (COM5). Wired up the programming header, got the LEDs lit up (both on and non-blinking when the switch is in programming mode).

Now here's where my trouble starts. First off, I'm not sure what I -should- be seeing when I turn the kit on in programming mode, but what I GET is two black bars, one each on the first and third lines of the LCD display. Is that right? If so, then all good.

Ok, but here's where the real problem is. I modified my makefile to point to COM5, just as explained in the directions. I go to do a make, get some lines showing that it's doing something, but then it just gets stuck at the "avrdude" line. (I've waited up to 10 minutes for it to do something, but nada.)

This is what I'm seeing when I go to do my MAKE command:


C:NerdKit_Projectsinitialload>make make -C ../libnerdkits make[1]: Entering directory C:/NerdKit_Projects/libnerdkits' make[1]: Nothing to be done forall'. make[1]: Leaving directory `C:/NerdKit_Projects/libnerdkits' avr-gcc -g -Os -Wall -mmcu=atmega168 -Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscan f -lscanf_flt -lm -o initialload.o initialload.c ../libnerdkits/delay.o ../libne rdkits/lcd.o ../libnerdkits/uart.o avr-objcopy -j .text -O ihex initialload.o initialload.hex avrdude -c avr109 -p m168 -b 115200 -P COM5 -U flash:w:initialload.hex:a


And then it just sits there. Forever. The system I'm running it on is my work laptop, WinXP SP2, Centrino, 2GB RAM. I've got Mcafee AV & HIP installed, although just for kicks, I tried disabling HIP, although it doesn't seem to have made a difference.

Thinking that maybe I knocked a wire lose, I turned everything off and put it back into RUN mode, and was still getting the pre-loaded happy message.

One thing I did try was to disconnect power from the kit while the MAKE was stuck at the avrdude command. When I do that, the "Connecting to programmer:." message comes up, but when I power the kit back up, I get the "buffered memory access not supported error (see below):


avrdude -c avr109 -p m168 -b 115200 -P COM5 -U flash:w:initialload.hex:a

Connecting to programmer: . Found programmer: Id = "bpY"; type = L Software Version = ?.?; Hardware Version = F.D avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device? make: *** [initialload-upload] Error 1


Anyone have any tips?

Thanks in advance!

UPDATE: Ok, now I get the black bars regardless of whether I'm in programming mode or not, and I can't get the happy message any more. Does that mean I did a partial flash?

Dang... Now I'm worried that I somehow blew up my MCU. :(

Oh, and just to pre-emptively respond to this question--I check my battery's voltage while under load, and it's still holding at 8.5v, so I don't think that's the issue.

Hi gzsfrk,

Your problem is a bit puzzling, I think your best bet is to email us support if you can include a close up picture of your setup I'm sure we can get to the bottom of the bottom of it quickly.

Thanks for the reply, Humberto! I think what I'm going to do is disassemble everything and then try reassembling it, making sure that all connections are indeed solid.

But can you verify for me one thing--when the MCU is in programming mode (pin 14 is grounded), should the LCD screen show the two black bars? Or should it look differently (blank, etc.)?

Thanks again for the quick response!

Still stuck--email sent with photos. <sigh> I hope it's not something completely stupid on my part. (Although if I have to choose between "stupid and easy to fix" or "not stupid but unsure how to fix", I guess I'll go with stupid and fixable. :)

Hi gzsfrk, the exact same problem is happening to me. I think the reason we get black bars is because the LCD is powered on but nothing is being sent to it because the flash on the MCU is erased. I don't think anything is wrong with the MCU because it has a fuse set to prevent overwriting of the bootloader. Hopefully we can get this straightened out. Please let me know if you arrive at a solution.

Below is the output from the terminal just before it stopped working:

Hey Brian! Sorry to hear you're having a similiar problem.

I do have a small update. Still not good news, but at least something different is happening now.

I completely disassembled everything in my kit (including removing the MCU from the breadboard), made sure I didn't have any small bits of wire shorting across any connectors, then rebuilt it very carefully.

Hooked up the power without it being in programming mode, and still get the black bars (which wasn't really a surprise). But this time, when I hooked it up to the programming header and went to do a MAKE, it actually started trying the "Connecting to programmer" step, although it would just keep trying and trying for awhile before finally giving me the "buffered memory access not supported" error. But on the bright side, it was pulling back the proper Programmer Id ("FDL v02"). So SOMETHING is working now where it wasn't before.

Hopefully one of the NerdKits guys can give some guidance on where to go from here.

Humberto sent me an email; he suspects a problem with my USB-Serial setup. I still get "programmer is not responding." A friend of mine has an older nerdkit, and I might be able to try out his serial adapter with another computer this weekend to see if it makes a difference. Here's to getting this thing up and running!

Have you tried a lower COM port? I was using COM17 (I think it was 17) & after I moved it to COM2, everything worked great.

May 05, 2009

gzsfrk's Avatar

I've used COM5 on my XP laptop and COM4 on my Vista laptop, and neither of them seems to be working. I read that there's a bug in the Windows driver that won't let you use a COM port higher than COM5. But since mine wasn't allocated that high, I don't imagine that was the problem.

Glad to hear you got yours working, Brian. Mine is likewise working now, but in my case, there was a small solder bridge connecting pins 12 & 13 of the serial board's MCU that was not supposed to be there. I heated up my soldering iron and removed it, and lo and behold! It worked perfectly, flashing the chip without hesitation the first time I tried to run it.

To anyone else having this problem, be sure to take very clear and close pictures of both the front and back of the serial port adapter and send it to the NerdKits support email. They are very responsive and provided me with excellent help.

Would someone answer the question as to whether or not you get black bars on the LED? I just got my header installed and powered it on, got black bars, and turned it off?

THIS IS IMPORTANT FOR WE WHO ARE NOOBs :P

If I flip the switch back so it's no longer in programming mode, it gives me the happy original greeting. I haven't even tried to flash it yet. I just came here looking for answers.

One suggestion for flashing is this: Your serial-usb device might default to 9600 baud. This is irregardless of whether you set 115.2Kbps elsewhere-- that just throws data out the computer at 115.2Kbps while the serial/usb device is set at 9600-- the MCU won't get hardling anything valid after the first few characters.

I'm running XP, and saw the 9600bps setting in the Device Manager when checking to see what COM port (I'm on COM 4) it was installed on.

I'm checking the traces of the header device now...

@BobaMoset. When the device is in programming mode you are supposed to see black bars on the LCD. Since the bootloader doesn't send any data to the LCD, it has no idea what to display. Go ahead and try to flash it see if it works!

Just to make a note for future users, it is my experience that on some Macs the USB cable needs to be plugged directly into the computer and not through a USB hub to work consistently.

It looks to me as if the first block of 128 is sent, and that either the return message (should be [0d]) is dropped or never sent.

Boot loader bug? Seems odd.

I "had" just received the serial adapter you guy's got, and i tried all the fixes on linux AND windows I knew when i connected it straight to the serial on the back of the linux machine and it came back with the same error your talking about, i knew it was had. So the staff sent me the "new" NK003USB which i got today and this "thing" is pure JUNK! Nothing compiles on either machine. Man are these guy's going to get a smashing. This one is obviously faulty too, i'm in Alberta and when i have to order these "things" from Texas! is bad enough, I think i might as well just drop these guy's, this "thing" and it's directions/pictures is completely unprofessional.

Humerto,

So, I left the NK for a day & went back connected it up & it burned successfully... again, only the first time. This would suggest to me that the Mac or butterfly gets into some state that clears only after a period of time (though I'll try it again tomorrow & see if I get the same results). The last time I tried 'make' it never came back.

[Btw, when I first plugged in the NK via USB, the OS asked if I wanted to configure it as a modem port... you might want to update your manual to mention this. I cancelled out of this & it shows up in the network config panel as an unconfigured usb-serial controller. <Mac OS 10.6>]

Is this possible, or do you have another suggestion?

How should the lights on the serial card be configured when it's plugged in? When trying to write to the PRAM? I see one light on solid (on the NK side), the other one lights up periodically.

Thanks!

Hi Dak,

Are you getting this error consistently after the first time you flash after a reboot of your computer?

I'm no Mac expert, but perhaps you can try unloading and reloading the driver. I think the command is something like the following:

sudo kextunload /System/Library/Extensions/ProlificUsbSerial.kext

to unload, and

sudo kextload -v /System/Library/Extensions/ProlificUsbSerial.kext

to reload. See if that gives it the right kick it needs.

Hi Pikoro,

The most common cause of this problem on windows is a low battery, or a loose wire. Make sure all your wires are nice and snug in the breadboard. If you have a multimeter around, check the voltage at your battery, make sure it is very close to 9V. Check the voltage between the +5 and GND rails, make sure that is very close to 5V. If you do not have a multimeter, just try a fresh battery.

If it is still failing, go ahead and send us an email to support <at> nerdkits, if you can include pictures of your setup, as well as which OS you are running, it would be helpful. We will try to narrow down what part is the one giving you problems and figure out how to fix it.

That's interesting, I use programmers notepad almost exclusively and have not seen that problem using the programming interfaces that came with my kit (2 piece setup - USB > serial converter through the inverter IC adapter). Do you have the 2Pc "programmer" setup (USB > Serial adapter with a small inverter circuit with 2 LEDs) or the current 1Pc (USB > Serial cable that goes out to the wires w/o an external board) ?

The reason I ask, is I did (and still do on occasion) get errors programming when using the serial port on my pc straight to the external inverter board without the use of the USB > Serial adapter.

The External dongle board while inverting the TTL signal from the uC does not raise the voltage to standard RS-232C levels which typically if I'm not mistaken are in the +/-10 to +/-15 volt range. The USB > Serial adapter doesn't care about the lower voltage however, some PC serial ports may especially if your cabling is long or not shielded well. This can lead to odd errors where sometimes communications work and others they don't.

I get 100% communications when using the USB > Serial dongle thru the board.

Now if you have the current adapter, you can ignore all the above as that most likely is expecting the TTL input of the chip and will work well with the 5v logic serial communications.

I just received my NerdKit today and put it together this evening. Programming it from my Mac did not work, with avrdude not communicating at all and then saying that butterfly_recv failed, and I found this thread.

I plugged the USB cable into the front port of my Mac instead of my desktop USB hub, updated the /dev name in the Makefile, and it worked like a charm. Hope that helps anyone else having a similar trouble.

Hi Sergio,

There are plenty of people here willing to help. Your best bet is to start a new thread, and describe the problem you are having in as much detail as possible. Pointing us to which steps are giving you problems is a start, but it is much better if we know why they are giving you problems, what about the step is confusing you?

If you post pictures of your current setup, and screenshots of the problem it would also help us help you.

igondjo32's Avatar

Now that you have seen the code, we need to use the command line to program the chip. 2. Open up the command line and navigate to the folder with the code in it. 3. List the files in the directory and make sure there is a file called Makefile. 4. Type “make” and press enter to run the “make” command. This command will look for the Makefile and use it to compile all the code, and will then program the chip using the binary files. (If you want to learn more about Makefiles, go to http://www.eng.hawaii.edu/Tutor/Make/ .) 5. You should see an output on the command line telling you what the program is doing. 6. If all goes well, one of the last lines should read “avrdude: --- bytes of flash verified” where --- is some number. This means that avrdude has successfully written the program onto the chip, and read it

all these are a little confusing is there away you can give me step by step instruction

Sergio, simple unplug one (or more ) of the devices using your Com ports!

As you are just starting you only "should" be doing one thing at a time so get rid of the distractions (other com devices).

You will not be using/needing all of them while you learn microprocessor programing and electronics.

gcc I believe is "Gnu C Compiler" the gcc compiler is made by the GNU open source group.

Once you are finished working with the Nerdkit simple plug back in your other Serial devices!

It means it's working! The wiring is right, the USB/COM configuration is right, the program compiled and uploaded to the chip, and it ran correctly.

Sergio, start a new thread you hijacked this thread and totally changed the subject I think if you want a answer you need to start a new thread.

C:>cd code C:codecd code C:codecode than C:codecodecd initialload C:codecodeinitialload>ls cd code has to be twice because when i downloaded it i had to extract the file which made it code code. i hope i make some sence out of it

Hi igondjo32,

As it was noted in another thread that you posted this question in. The old program gets overridden when you write a new program to your chip.

I struggled with the same error and failure to write. For me it turned out be my wire from +5 to pin 1. I noticed when I was re-re-rechecking my usb hookup on the board that there was no wire from +5 to pin 1. I remembered doing it and wondered how it could have fallen out. Then I noticed a wire from +5 to pin 15. I corrected the wiring and the problem was solved.

Hi everybody, I tried to unplugged everything and then replugged,but I still get the same result. The following is the error i got when i load the first program to the chip:

Found programmer: Id = "Huh? Go"; type = ' .S Software Version = t. ; Hardware Version = ' .S avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device? make: *** [initialload-upload] Error 1

I found a post on May 04, 2009 by gzsfrk earlier on this discussion, but it seems like he found the solution. Any suggestions would be great.

Hi Tou,

This error definitely means that your MCU is not in programming mode. Make sure your programming switch is installed correctly, and in the right position, then reset power to the chip. You should see two black bars on the LCD when the chip is in programming mode.

Hey guys, I just got the same problem, but I've fixed after struggling for about 30 minutes. I made 2 mistakes: 1, I forgot to GROUND breadboard 25 ! I'd like to comment to the next version of Nerdkits manual that this part needs to be highlighted! 2, the COM port actually keeps changing once you unplug then plug it back into the PC. make sure that you get the correct COM port# !

A great hint is that, once your kit is in programmable mode, you should see 2 dark blocks just in front of the "Congratulations!".

Hope it helps.

Having exact same problem as Pikoro (Dec 11, 2009). Using Programmer's Notepad on Windows 7, and COM5. Everything configured fine on breadboard, initial happy program worked, and the first time that I downloaded the new code to the MCU all worked great. Code downloaded, and new text came up on LCD just fine. Since then, it will not do it again, and my message is exactly the same one that Pikoro described (except I'm on COM5). AVRDude reading great, but then AVRDude writing error that programmer did not respond to write block make.exe, with initialload-upload error 1. Process Exit Code: 2 Time Taken: 00:12

Haven't tried configuring things to run Make from the command line, which he said fixed his problem. But then why shouldn't the existing code that worked the first time work a second time? Hmmm.

Messed with it for last hour with no success, and calling it a night. But it's definitely a repeatable problem.

Figured it out. To test that I was getting new code uploaded to the MCU, I had changed the text being written on the LCD. One line was 21 chars instead of 20. As soon as I fixed it to only 20 chars, everything works fine. Doh! Have downloaded different text a handful of times now without any issues.

I seem to be having the same problem some others are having. Unfortunately none of the responses I saw worked for me. I have a laptop with win7 I have made different changes to the location of the make and initialload file to see if it made a difference. I have the make file in the same folder as the program which seems to be what the error message is saying is wrong. But nothing seems to be working. I've even tried changing the COM port number but that didn't make any difference either. Any help will be greatly appreciatedMake screen

Well I managed to figure something out but still don't think it's right. I was able to upload the initialload. I had extracted the download from nerdkits to one loactiona nd then moved it. I did move it all so I thought that should not have any problems but after much anguish I decided to delete what I had moved and re extract the zip file to where I wanted it. But I still don;t think something is right. I changed the text output to the LCD in the code but the LCD still says the same thing. And I got an error 1 at the end of the make.

Last post my imbed forced my text into one long line so this time I will post my imbed image in the next post. Thanks Steve

Well even my last post got strung out into a long line.

Maybe have to use Shift-Enter to force readable text.

make file that worked but there still seems to be something I'm not doing right

Hi Steve35897,

If you are still having problems here is how to use the -F override:

AVRDUDEFLAGS=-c avr109 -p m168 -F -b 115200 -P /dev/cu.PL2303-0000105D #USB3

Try that.

What does the -F override do?

I think I figured out my problems. I originally unzipped the nerdkits download to one folder but quickly realized

that was alot of typing in the command prompt window when trying to "make" it so I cut and pasted the whole

"nerdkits" folder so I thought it should be OK. Somewhere in this forum I read a suggestion to delete the

download and re-extract. After I did that my original problem is gone. Then I had some other learning to do

such as the .c at the end of the program name. Somehow I thought that when I edited and saved the program in the

Programmer's Notepad that was automatcally done for me.

What does the -F override do?

Hi Steve, look at your screen shot from 4 days ago.

Notice the forth and third line from the bottom:

avrdude:   Device signature = 0x1E9406 
avrdude:   Expected signature for ATMEGA328p is 1E 95 0F
           double check the chip, or use -F to override the check.

So the -F is just an override of the signature check.

Un zipping the download often causes problems (to much thinking).

Hope you get it running, if not let us know :-)

Dak's solution resolved the issue I was seeing on my Mac, latest AVR, OSX 10.7.5.

sudo kextunload /System/Library/Extensions/ProlificUsbSerial.kext
sudo kextload -v /System/Library/Extensions/ProlificUsbSerial.kext
run make <!--- fails first time
run make <!--- works

make change to program and repeat.

Crazy that you have to unload and reload serial driver every time but at least it works now.
