is there a doc describing memory map and what dev in /dev is map to which physical dev?
is this in the device tree? if so, where can I find and view that?
Greetings @swc,
Not sure if this is 100% what you’re looking for but, the memory map on our modules is a SoC specific, far as I know. You’ll need to most likely reference the i.MX8 Reference Manual from NXP. Last I checked there should be a section in the manual called “System Memory Map” that will give the information you may be looking for.
As for mapping physical memory to /dev, for the i.MX6 this was possible to define at the device tree level. I assume it’s a similar process for the i.MX8.
Best Regards,
