I recently upgraded to Petalinux 2019.2, and I used to be able to access /dev/mem as root on previous version. I did find a previous post that asked to get in to the Kernel Hacking menu option to disable devmem filtering, but that didn't help any, as it was already disabled. Does anyone have any other idea? I have the character device enabled in the kernel config, as well as disabling security options (I believe) that protects /dev/mem.

In the kernel configuration, there's an option called strict devmem filtering (or something along those lines.) You could turn that off and see if it makes a difference
