STM32MP257F-EV1 rebooting at hpdma after otp write

Hi,

I have a  OTP provisioning script that wrote OTP 1 with value 0x000000ff, executing a partial close of security state B. The board now passes ROM/FSBL/OP-TEE/U-Boot but resets when the Linux kernel probes the first RIF-protected peripheral (HPDMA3). Disabling HPDMA3 in DT causes the same reset on HPDMA2, indicating closed-state RIF policy is being enforced globally regardless of the device tree configuration applied by OP-TEE

Can the board be returned to a open state using an rma procedure? 

Kind Regards,

Jack Redpath
