Hello,
we're maintaining assembly projects to teach baremetal assembly programming on STM32H750 board.
Project used to compile without and warnings, but lately we're getting new errors.
Project is stripped down to bare assembly and probably something is missing...
This is output :

Project works, we can upload it and debug it, not sure why it says 4 errors...
Any advice how to fix the project ?
Thanks in advance,
regards.
