!!! OUPS... MEMORY ERROR @ 0x00000000 !!! Are you sure that: MEMORY ADDRESS IS VALID? TARGETED MODULE IS CLOCKED?
And I was not able to get some --help from it. Is it possible that omapconf is not compatible with a 4.7-rc1 kernel?
It just uses /dev/mem.. Hmm you're trying to read physical address 0 :) Doing omapconf --help on my omap5-uevm produces tons of help options.
No idea why it fails. I just compiled from latest git sources.
If I find spare time (what is that?) I can try it on the 5432EVM (I tested on BB XM) and with strace.
Also check out Tomi Valkeinen's rwmem on github, that's handy for checking a single register.
We have devmem2 [1] which is quite similar.
