Hello!
I’m working with a yocto / OE image for the DB410c. The board came with Windows IoT programmed on it.
While searching for a suitable location to store commissioning data I stumbled over that eMMC RPMB partition. Trying out mmc-utils to access that partition, did not led to success. E.g. reading the counter using mmc rpmb read-counter /dev/mmcblk0rpmb
returns RPMB operation failed, retcode 0xffff
.
Do you have any hints on the RPMB? Is it usable on DB410c at all?
Regards
