So Finally I got the signature of the board from AS7 device programming. What I did was I Changed the lower voltage limit of the programmer from its configuration exe file which was located in the bin folder of Polulo AVR Programmer and then lowered ISP clock to 52Khz and got the signature of the device at 3.1V. and from the Fuses section of device Programming I Programmed and verified it and everything was alright. But If I close device Programming. and then Rerun it from AS7 it again gave me the previous Error
ERROR: Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool)
I think it has something to do with Fuses of AS and I am not really aware of it. It might be relevant to saving the configurations that i did.
I need suggestions for this Error. Many thanks
