SC573 - Problem with securely locking device


I run into exactly the same problem as described in

While I can successfully write encryption, debugger and public key, I cannot securely lock the device, neither with 'adi_rom_lock()', nor with writing a 1 directly to OTA address 0x48c.

The return value always indicated a successful write operation.

I also tried with cldp -proc ADSP-SC573 -core 1 -emu 2000 -driver "OTPProgrammer_Core1.dxe" -device otp -cmd lock, with the same negative result.

Any ideas?

Best regards,
