Design Advisory for Zynq UltraScale+ MPSoC/RFSoC: 2018.x/2019.x XilSKey does NOT exit BBRAM Programming Mode


In the 2019.2 release and previous releases of XilSKey, the function XilSKey_ZynqMp_Bbram_Program() never exits the BBRAM Programming Mode.

After calling this function, any direct access to the BBRAM registers will be invalid and operations such as BBRAM erase will not work as expected.

A Power On Reset (POR) is currently required to exit the BBRAM Programming Mode.

A patch for the 2019.2 version is attached to this Answer Record.

This issue will be addressed in the 2020.1 version of XilSKey.
