ADRV9026 initCal TXBBF error

Hello,

Sometimes, during init calibration I run into this:

CpuCmdStatusWait() failed due to thrown CPU error. Is device in correct state for calling command?
ADRV9025 CPU Command Error
TXBBF:Calibration results are invalid

It happens around 5% of my runs, and then ARM is not accessible any more, a reset and a new initialization is required.

Consider we have a multi-adrv9026 equipped board and the problem is randomly affecting one of the 16 chips, not always the same.

Any suggestion for a further investigation ?

BR
