Under 9.7 FW I get 2.00x. After power on I did not a serial number.
I follow the instruction to burn the bootloader, but it's not work for me.If you don´t see your Serial Number on the Display after powering up your device, you either have a hardware defect, or there´s no Bootloader installed.
There are an error message in the AVRDUDESS 2.17.
Can I overwrite the warning with -F Force option without bricking the device?>>>: avrdude.exe -c avrisp -p m328p -P COM8 -b 19200 -e -U flash:w:"C:\Users\jzapf\Downloads\truSDX-initial_Bootloader.hex":a -U lfuse:w:0xFF:m -U hfuse:w:0xD6:m -U efuse:w:0xFD:m
avrdude: AVR device initialized and ready to accept instructions
avrdude: device signature = 0x7f7f7f
avrdude error: expected signature for ATmega328P is 1E 95 0F
double check chip or use -F to override this check
avrdude done. Thank you.
