Details

Data corruption can occur when CSI attempts to make writes to PCR/HWA/HSM/DMM, which are not 8 byte aligned.

Workaround

CSI2 to DMM transfer should be with 1 line ping-pong enabled when DMM is operating in CSI2 mode.

Access from CSI2 to any PCR or HWA or HSM space needs to have 1 of the following constraints:

• CSI2 payload size per line should be multiple of 8 bytes.
• CSI2 should operate in 1-line ping-pong configuration.
