We have PROCONHSMCOTP configured as:
1. HSM17X HSM Code Sector 17 Exclusive enabled
2. HSM16X HSM Code Sector 16 Exclusive enabled
3. HSM6X HSM Code Sector 6 Exclusive enabled
4. HSMDX HSM Data Sectors Exclusive enabled
5. HSMBOOTEN HSM Boot Enable (Expected) enabled
Therefore we cannot read HSM on the board with other hosts or debugger. Is there a way to modify these UCB options after this point?
Thanks

No, per page 954 of the User Manual. Once either set is confirmed, the UCB cannot be erased.

Is the UCB confirmed? If it is still unlocked, you can reprogram the UCB.

It is confirmed. Is there any way to unlock at this phase?
