UFI box software can not read or write RPMB area

UFI box software is can't get any data from RPMB, and readed file contain old read buffer.

EasyJTAG Classic software can fully work with RPMB with user-created key. But device CPU use own key, and device CPU can't work with user-created RPMB key, it doun't know this key.


If anybody want to test - you need use any OLD eMMC, which has the ability to update the firmware

To test RPMB work ability:

1) write firmware yo eMMC to clean RPMB keys
2) Use EasyJTAG Classic software to read-write RPMB area with you key
3) you can check the read and written data as many times as you like and make sure that the program can actually work with the RPMB partition.
4) you need write firmware yo eMMC after to clean RPMB keys for use eMMC at another device
