So i'm haveing some trouble..
I'm using an analog mux to switch the pins needed when doing ISP programming. i believe they are pins PE0 and PE1 (i don't remember off hand).
Anyway, i'm switching between them because I need those pins for other things. I can't have them as programming pins only.
But.. the problem is.. i can't program. I just get errors.. i check the Mux and it works as it should, the programmer cable is good (i used 3 different cables, that worked with other mega128 boards)
i'm just looking fr suggestions.. the Oscillator i'm using also works fine.. i checked it with an O-scope.. the only thing that i think is possible is the chip itself...
