Thanks very much :-) I did not know about the eprom -p and it's actually very nice to have it. The info you gave me are mostly about the address of those peripherals in physical memory. What I was after was the virtual address at which peripherals get mapped inside the kernel. This is specific t

raspberry pi 4 peripheral address

2021-04-19 Thread Alessandro Pistocchi
Hi, I am playing around with openbsd kernel source code on a raspberry pi 4. I have a couple of questions: Does openbsd use low or high peripheral mode? At what virtual address does openbsd map the peripheral base address ? I had a look at the source code but that part is still a bit cryptic for
