I’m trying to get going on bare metal programming with my rapsberry pi 4b and I’m encountering an issue when trying to run it on 64bits. Whenever I try to write to the GPIO SET0 register, the program completly stops. When I use a similar code in 32 bits, it works just fine with the exact same base addresses and offset.
