I used Arduino UNO as ISP to change the fuse setting of Arduino Pro Mini. Using avrdude cmd, I successfully changed it to 8MHz setting. Due to curiosity, I decided to try changing it to 128kHz. But that ends up me being unable to further program it. The Pro Mini still works but just cant change fuse through avrdude cmd, burn bootloader and upload. Does 128kHz really leave atmega328p like that?
On one computer, the below error appears.
avrdude: stk500_recv(): programmer is not responding
On another computer, the below error appears
avrdude: Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check Wrong microcontroller found. Did you select the right board from the Tools > Board menu?
There are actually more errors because I trial and error different ways to solve it, i.e Nick Rammon's Atmega_Board_Programmer, cmd command with varying parameters (baud rate, programmer), inserting capacitor on UNO. But I dont remember every one of them because the
not in sync:resp=0x.. differs from time to time
There is one method which I have not try, high voltage programming mode. I would try it out if it was detachable but atmega328p on Pro Mini is SMD. Is it possible to high voltage program on Pro Mini? Ultimately I am stuck.
Ignoring what I have done, I would once again like to try out every method you guys recommend. Hopefully everything can be step by step and the thing I want to know most is the setting of '
Processor' and '
Programmer' in Tools.
I would give my best response possible to you guys who is willing to help me out. Thank you
