Hi there,
I am trying to solve the 3rd exercise for lession 01 on a Raspberry Pi 4B. So far I could manage
to adapt all the code for the 4 with the help of the hints in the issues. But I do not manage to
get all the cores running, just the processor 0.
I even built the other user solutions without any success.
UPDATE: With uart_2ndstage=1
What am I missing? Thanks for you help!
