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:

Thanks!

Phil.
