Reading fuses from firmware - wrong values when executing
Hi, I will make a strip down file, see if it has the problem and post. When testing with the JTAG debugger no lock bits are set - it reads 0xFF when it works, 0x94 when it fails....

Switch statement goes wrong unless optimisation is -O0
Hi Stefan This is from a debug session on the chip. I see that just before the LPM executes that the Z register ( R30,R31) is loaded with 0xE8 0x01, which is the shifted 0xF4,0x00...
