Hello, i am having a strange problem and need some help on solving it.
I am using AVRISP MKII to program my ATmega2560, however the MKII cannot even get Device signature. I am attaching a screenshot... The LED on MKII keeps blinking in RED. I have confirmed the pins config and even tried connecting the ISP connector oppositely still no luck.
I have confirmed that MKII is working properly by programming an ATmega32.
I have checked the connectivity to MISO, MOSI, and SCK pins and everything seems to be OK.
I have confirmed that ATmega2560 is working by running the already burnt code (it contains some UART stuff and its working)
I think there might be a fuses problem ( a wild guess) but when i cant even read Device ID how can i read fuses...
I have tried narrowing down everything i knew still i cant get to the root of the problem and/or solution.
Edit: i am also using SDcard on same pins but i removed the card before programming still no luck
Edit2: i have tried different frequencies to program it still nothing works
