I am programming, ISP with 6 wires, an atmega48 mounted on my PCB. All is well, sort of ...the programming fails!! (using stk500 as the "programmer".
It also fails when I do a "verify fuses"....is there a way to tell WHAT fuses are failing?
reading fuses 0x53, 0x535 ok
WARNING fuse bit verification failed ----but no other info. how do you diagnose this??
By the way iu may have programmed the reset line to be disabled---can this be undone? And how?
