Hi Fred. How can I reproduce it? Thank you. Michael Rolnik
Hi Michael, First sorry for the patchew noise, I didn't meant to sent a patch just an inlined diff. For the reproducer, that's pretty straight-forward with v6.0.0-rc5: $ cat > foo.S << EOF > __start: > wdr > EOF $ avr-gcc -nostdlib -nostartfiles -mmcu=avr6 foo.S -o foo.elf $ xxx/qemu-system-avr -serial mon:stdio -nographic -no-reboot -M mega \ -bios foo.elf -d in_asm --singlestep IN: 0x00000000: WDR Segmentation fault (core dumped) Note that I put "--singlestep" here to avoid translating NOPs after the WDR, it breaks without as well. Fred
