I can confirm CubeProgrammer v2.11.0 has finally bug fixed this (writing to OTP lock area for device ID 0x413).Regards,Peter

This issue is still not fixed in STM32 CubeProgrammer v2.10.0 (tested the 64-bit version).Quick fix is to change "Data_Base\STM32_Prog_DB_0x413.xml" manually. But for deployment within our company this is sub-optimal...

I can confirm the lock bytes can now be written in the OTP area of the STM32F407IG (0x413).Bugfix/change in STM32_Prog_DB_0x413.xml:<Parameters address="0x1FFF7800" name=" 512 Bytes Data OTP" size="0x210"/>Regards,Peter

I tested it, but it still doesn't work.STM32F407IG and ST-LINK V2. Verified by reading the lock bytes afterwards - nothing changed.Kind regards,Peter

Any chance this will be solved in the near future?Regards, Peter
