As you can see A19 and A20 are connected jumper is set to 5V i.e it's closed. so why the hell wont it write i've tried diffrent 29lv160 settings like atmel and generic etc no success always fails 25 percent no matter what dump i write to the chip with i have searched the forums tried all the things suggested but i am getting really frustrated as i havn't been able to write to any chips since i ordered this TRUE USB PROGRAMMER! |
