Microcontroller Programming » Location to find bootloaders for ATmega series

i'm thinking of going to smd form ATmega MCUs, so i need a bootloader for them. Any place i can get them, even possibly preloaded?

You're going to need a programmer (ISP, etc) to be able to load the bootloader... The bootloader is included with the nerdkit code.zip download... But then again, if you have a programmer, then you really don't need a bootloader then do you? ;)

Kinda a catch 22... ;)

I'd be more than happy to load a bootloader on one (or however many) for you, but it would have to be mounted to a "breakout" board so I'd have any easy way to get to it.. Not to mention I'd of course ask you to pay shipping both ways, and frankly you could probably buy and/or make a programmer for the cost of shipping a few chips...

i would actually like that, since i'm not experienced in using a breakout board programmer, but i must ask, is the nerdkits bootloader compatible with ATmega328( ATmega328 ) since i'm going to be trying a project with them and i do not know how to design/modify a bootloader for these, so if this is possible, i would be happy to take you up on that offer and pay for the chips/materials and shipping.

Hi tech20,

We do have copies of our bootloader ready to go for the ATmega328P and also for the ATmega644P. I am still working on cleaning it up / packaging it up, but I would be happy to e-mail it to you in it's present state if you're interested!

I would like that, since I'm looking at some boards for it right now, and have a smd board for these(though at my current soldering skill, not sure if i would take that up as a option ), so i would like you to send me that package if you can.

also, out of curiosity, are you ever planning of selling nerdkits/upgrades_to_the_Nerdkit with these type of ATmegas?

bump, i found a computer with a parallel port, so can you send me instructions for the hack along with the bootloader (I'm also working on a Linux computer)

LOL, isn't it amazing how many things we "forget" about??? The other day somebody came into the office with a 3.5" floppy and said they needed a file off of it but "couldn't find" the floppy drive in their workstation... You would have thought they came in with an 8" floppy by the look I gave them.. LOL...

Try finding a motherboard that still has ISA slots! ;)
