We are using ATmega328P-MMH chip for the project. we have made 2 boards. when we are programming the Chip using the progIsp only once we are successful to load the code but after that it showing “program enable chip error”. It happened on both boards. Please find the fuse bit information in attachment and also schematic for the IC. I am using internal oscillator.
plse note that Arduino uno board I have tried same code it is working on uno board.
Requesting you to kindly provide help ASAP.
