I see in this thread you test some binary: https://lists.gnu.org/archive/html/qemu-devel/2019-06/msg02291.html https://github.com/seharris/qemu-avr-tests/blob/master/free-rtos/Demo/AVR_ATMega2560_GCC/demo.elf Can you add a test that uses your binary and check it does something? That would help maintaining your work over time. Avocado tests can be quite simple, i.e.: https://lists.gnu.org/archive/html/qemu-devel/2019-06/msg06515.html Since you added support for the USART, you can also add some assembler instructions to use it to this test: https://git.qemu.org/?p=qemu.git;a=blob;f=tests/boot-serial-test.c;h=24852d4c7d0b3fc08fb0dab35f32372a0b2c46db;hb=HEAD Thanks! Phil.
