Bootloader : Atmega2560 16au and Atmega2560 8au and extarnal crystal of 8Mhz.

Hi

First of all thanks alot for your contribution for us.

I have used your bootloader for Atmega2560 16au with 16Mhz external crystal and its works like a wonder.

But in my new project I have 3V power supply so I am planning to use low external crystal so that I can operate the Atemga with low frequency and so the voltage will be go as low as possible.

My first question:
I uploaded the bootloader using 8Mhz external crystal and it went sucessfully but I am not able to upload sketch.

so here is my question : Can i ran Atmega2560 16au with 8Mhz crystal and will it work at 3V ,without any risk?

My second question:
As i do not having Atmega2560 8au right now so i am not able to test. will your bootloader works with Atmega2560 8au and external 8Mhz crystal. or before burning bootloader I need to make any changes.


Sorry to ask you such a long query . But I have really spent lots of time looking at this and finally today a made a post every where.

Please respond me.

Thanks a lot. I will wait for your response.

Yes, I had issues copying the template this time

Cross-posting, huh?

The template, which should work for you, is:



If it doesn't please explain in what way.

Yeah, it was a PEBCAK situation Nick. I really shouldn't be attempting to do anything that early in the day.

I get those late in the day, so don't feel too bad about it. :)
