Hello Ray, Most probably this really is the programming speed issue. When I was new to AVR and saw ATMEGA32A for the first time, I'd spent about an hour thinking that all my MEGAs were faulty. Finally I lowered the speed and everything became OK. You need to set programming speed to at most 1/4 of the clock speed (if I remember correctly), so for the default clock speed of 1MHz, programming speed must be 250KHz or lower. I'd recommend 100KHz for the start, then you can try increasing it or adjusting MCU's fuses for a higher internal clock speed. So, try:
avrdude.exe -c usbasp -p m32 -B100kHz -v Tuesday, May 23, 2017, 5:53:01 PM, you wrote: RM> This is going to be a usbasp issue most likely.
