Hi all, I’ve been here a few times, but I’ve stopped lurking because I’ve got a problem.
Background: I bought two Nano ATmega328P clones, I needed to(and expected to) install drivers, due to them having ch340 chips for usb communication.
I think I got that right, both boards show up under “device manager” as ch340 devices, is that correct?
I did not expect the next problem.
I tried to upload a sketch, but that failed. It also turned out that out of the four leds on each board(PWR, RX, TX and PIN13), only the PWR led was working. The reset button, when pressed, also did not seem to do anything(such as blinking the PIN13 led).
After some internet searching, the cause that fit the symptoms turned out to be a corrupted/non-existent bootloader.
I took out my Mega 2560 clone and after a bit of thinking, started following the necessary tutorials for burning a bootloader via arduino-as-programmer. I ran into more problems, and could not burn a new bootloader.
I ran into the dreaded 0x00000/0x0ff000 nonsense signature error type of stuff, but the curious thing was that I got the same error, even when the nano clone was not wired up to the mega2560(acting-as-programmer).
So what could my problem be? Is there a chance that the ATmega328p chips on my nano boards are fine after all? Could there be a problem with the mega2560 clone preventing it from doing its job?
I don’t think that I touched the fuses on the nano boards, unless pressing -F on my keyboard can do that(without changing any IDE settings)? :-[
If I am missing any out any info that could help solve the problem, just tell me and I’ll post it. Its a bit late at night at the moment.
