RE: Xprog programming device silent error
Thanks volavka firmware isnt the issue I don't think tried to flash the firmware you posted still get device silent.
So maybe is caps its as if xprog doesn't wake not sure any ideas ? Update :tried changing the 4.7uf cap and 11mhz crystal next to MCU no difference still same error what led usually comes on when you plug in xprog green ? Found a cap on underside of board if I hold my voltage tester between the two ends for a second while usb plugged in white bulb on xprog comes on red and stays on until I unplug. when I plug in again it is off till I put tester between pins so might be part of problem anyone got any idea what capacitor I could replace it with ? Also seems about right as pop came from around crystal area near MCU and and the underside cap I mentioned is attached to one of the crystals legs maybe heat from crystal while I was changing MCU popped it ![]() Here Right one in circle attached to 11mhz crystal leg just below ![]() Update: a lot of schematics that use atmega64 has 2 x 22pf caps on legs of crystal so gonna try that first let you know results later ![]() ![]() ![]() |
