Can't load Bootloader into TruSDX
Posted: 07 Dec 2022, 23:05
Hello, I read most of the similar threads of failed load of Bootloader and I conclude my 328P chip is dead. Just want to confirm what I see.
First attempt, I got the verification error on the first byte so I tried again and got the yikes! Invalid device signature. Tried again - same thing.
Then did the -F (I now know we are not supposed to do that so don't scold me now) and got the verification error, first mismatch at the first byte.
I went through the the procedure from the start 3 more times with the same faults. I then took another arduino uno board in place of the TruSDX and tried to load it and it loaded without a problem so I now know my test cable and adrino ISP unit is working. The arduino uno board showed the right signature while the TruSDX never did show it (always ffffff)
Does the display ever show any characters before the bootloader is loaded? Mine has never displayed anything. Current input is around 60mA with the RF board attached.
I was part of the US group buy #2. I just got busy to finish it sooner.
I just ordered a Hot air station to swap out the 328P if I have to. I can pull a chip from another uno.
I also just ordered a Classic kit from Aliexpress up tech store to start over without soldering SMD chips in myself on the main board in case that was my problem plus I wanted the classic bands and didn't want to go through capacitor changes/purchases and toroids.
Thanks,
