Edit: I am using SEGGER J-Flash for software downloading. I need to understand wiki.segger.com/images/7/78/STM32L5_Lock.jflash and add my existing .jflash file.

Hello @gopikrishnan ,

To enable RDP level 2 on STM32L5 series boards, you can follow these steps:

  1. Connect the Board to your computer via the Segger JLINK.
  2. Launch the STM32CubeProgrammer software.
  3. In STM32CubeProgrammer, connect to the target device using the JLINK interface.
  4. Once connected, go to the "Option Bytes" section in the STM32CubeProgrammer.
  5. Set RDP Level to 2 (select the value corresponding to level 2: "0xCC"), then click on "Apply" to set the RDP level to 2.

Hi, I am using SEGGER J-flash. I am trying to understand how this will impact my current jflash with none of init and exit actions.
