I tried disable ROP level 1 to level 0 by ST-LINK Utility and STM32CubeProgrammer, but it is not success.

Thanks in advance.

Hello @DLe.4​ ,

Please provide more details so that we can help you. You may check the RM0090 for more details. When read protection level 1 is set, there is No access (read, erase, program) to Flash memory or backup SRAM can be performed while the debug feature is connected or while booting from RAM or system memory bootloader. So, a bus error is generated in case of read request.

Could you please share screenshot with STLink utility or CubeProgrammer to understand the issue.
