I have an S32G-VNP-EVB3 board running Linux using the NXP provided BSP 40. I have enabled the EDAC system in the Linux kernel to montior sbes and dbes however I do not see it in the filesystem. Makes me wonder if EDAC is actually enabled on this board? The amount of available memory seems to indicate that it is; though I could not find the memory node in the device tree to double check. Any way for me to be sure?
Expect to see edac information here,
/sys/devices/system/edac/mc # ls
power subsystem uevent
System memory,
/sys/devices/system/edac/mc # cat /proc/meminfo

Hello, @minersrevolt
From BSP perspective, it does not support EDAC at DDR level.
Sorry for your inconvenience.
Best Regards
