How to access peripheral registers and physical memory from user space

[dimax]

Hi,

I'd like to be able to read/write for debug purposes peripheral registers of the MPU and MCU from Linux user space. Of course all under root permissions.

The most straightforward way should be doing it using /dev/mem but I'm not sure if it is a best way to go. Any thought would be highly appreciated.

Thanks.
