Hi, Recently I added a call to eeprom_read_byte from avrlibc to my project but it results in AvrDevice::Step returning -1. This is wrong I believe. I turned on trace output which resulted in the following:
../Debug/lcmeter.elf 0x12fc: __eerd_byte_m8 CPU-waitstate 0 0 ../Debug/lcmeter.elf 0x1300: __eerd_byte_m8+0x2 OUT 0x1f, R25 EEAR=0x0 0 ../Debug/lcmeter.elf 0x1302: __eerd_byte_m8+0x3 OUT 0x1e, R24 EEAR=0x0 0 ../Debug/lcmeter.elf 0x1304: __eerd_byte_m8+0x4 SBI 0x1c, 0 EECR=0x1 EEPROM: Read = 0x0 0 ../Debug/lcmeter.elf 0x1304: __eerd_byte_m8+0x4 CPU-waitstate 0 ../Debug/lcmeter.elf 0x1306: __eerd_byte_m8+0x5 CPU-Hold by IO-Hardware 0 0 ../Debug/lcmeter.elf 0x1306: __eerd_byte_m8+0x5 CPU-Hold by IO-Hardware -1 -1 The number after "CPU-Hold by IO-Hardware" is the actual cpuCycles, so it turns at some point negative and of course simulation returns as if there was a breakpoint.
