thinking it may be a current supply problem I tried three sources of power

a) regulated 5 volts from a mains power supply I built years ago the last time i tried to learn some digital electronics

b) 13v unregulated supply (From same power supply) via nerd kit v regulator set up and finally

c) nerd kit set up from 9 volt battery (response shown above - the same with all three supplies)

I don't know the current characteristic for the supply I built years ago. However it did read 5 volts across regulated terminals thru out.

Not sure what to do next

Simon

The power supply i built was from "Practical Computer Experiments" by E A PARR published 1980

![Power Supply](http://i.imgur.com/3LCJD.jpg)

Sorted!

forgot avr-gcc-select 4

Works with my power supply!

I changed my .c file and was unable to flash led_blink I changed .c file back to original still unable to flash

tried various combos of rebooting mac, unplugging /reconecting usb, removing .o & hex files no joy

Would appreciate some help

Simon

Hi swarg,

Could I take a look at your makefile, I am concerned that you are doing two read cycles for every write cycle attempt. Also are you still using the power supply, or are you using a 9V battery?

Humberto

Hi Humberto

I am using my power supply - in fact the unregulated 13 v thru nerdkit 5v supply chip. I checked circuit with voltmeter and found 5V where I would expect it.

I have to confess that I tried so many combos that I lost the logic of the plot!

However at one point I successfully downloaded initial load again - don't think I erased O & hex file from folder - I am not sure.

my make file is as follows;-

"

GCCFLAGS=-g -Os -Wall -mmcu=atmega168 LINKFLAGS=-Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm AVRDUDEFLAGS=-c avr109 -p m168 -b 115200 -P /dev/cu.usbserial LINKOBJECTS=../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o

all: led_blink-upload

led_blink.hex: led_blink.c make -C ../libnerdkits avr-gcc ${GCCFLAGS} ${LINKFLAGS} -o led_blink.o led_blink.c ${LINKOBJECTS} avr-objcopy -j .text -O ihex led_blink.o led_blink.hex

led_blink.ass: led_blink.hex avr-objdump -S -d led_blink.o > led_blink.ass

led_blink-upload: led_blink.hex avrdude ${AVRDUDEFLAGS} -e sleep 0.5 avrdude ${AVRDUDEFLAGS} -U flash:w:led_blink.hex:a

"

Humberto an update

I have since tried again . I fused my power supply - I suspect a 5v short circuit problem.

Obviously worried that I may have damaged components.

I found 9v dc supply and successfully downloaded "initial load" to device.

I tried again to download led blink * 2 (second attempt after deleting o & hex files)

following is my terminal log

"

I have not changed makefile from one in thread

Simon

Simon, lets see you makefile.

Use the "Indent Selection as Code Block" button.

Just copy and paste your makefile to the forum post window highlight it and click the button.

Or put four spaces before each line.

That way we can copy and paste your makefile for testing?

It looks like you are running make twice and getting different results or is that just because of the messy posting?

Anyway give us a fresh clean look at your makefile.

avrdude ${AVRDUDEFLAGS} -D -U flash:w:initialload.hex:a

From Mike's post

The "-D" flag stops avrdude from erasing again on its second run.

I'd also try again without the delay, just to see.

Could this be problem with C file I have read various threads suggesting need to reboot mac between attempts to flash

Not sure what to do next

Simon

Well it never hurts to try rebooting, but that is a pain. I have had to do that with OS X 10.6, certainly is a pain but try it.

Now:

Could this be problem with C file I have read various threads suggesting need to reboot mac between attempts to flash

You are jumbling your thoughts.

First thing:

Could this be problem with C file

Well try a different project. What project are you working on?

Then:

I have read various threads suggesting need to reboot mac between attempts to flash

Well you certainly should not have to reboot with each compile, but as I said try it.

I have had lots of different problems with OS X, I have gone days where I could not compile/load a project and then the next day everything would just work.

I used to have to pull the USB cable after each compile.

I wish I could run LION then I could be more helpful. Actually I am glad I can not run LION I've gone through enough problems.

Ralph

Update

after restarting computer, unplugging and plugging usb cable

successful download of led_blink

Please Please would somebody hazard a guess as to what this process might be doing to allow the chip to be programmed

Simon

Hi swragg,

At this point it migth be a dying battery that is affecting the stability of your programming. Flashing a new program takes lots of current from the battery (relative to reading the flash).
