Has anyone else encountered problems with the POR and/or button reset on this board/chip? My trivial application code (which at the moment just lights an LED on PORTG immediately at startup) won’t run reliably every time after power on or pressing the reset button. Sometimes the LED lights, other times the board just seems to sit doing nothing.
Fuse settings seem to be OK as far as I can tell from the data sheet… LFUSE=0x62, HFUSE=0xD9, EFUSE=0xF7
I tried enabling BOD but it didn’t seem to improve the reliability. Programming with an Olimex ISP-500 and avrdude.
Any suggestions much appreciated! Thanks
