STM32H735G-DK: Device in lock up state, possibly "read and debug" protected. Use monitor commands to remove the protection // Failed to execute MI command: load

[code-by]

Hello

I have:

1. STM32CubeIDE (Version: 1.10.1, Build: 12716_20220707_0928)
2. STM32H735G-DK board

I have tried running a demo from TouchGFX app (4.20) and it flashes and run well, but I have a problem with running 'FreeRTOS' example created in 'Example Selector' in STM32CubeIDE. When I click Run button, I got the following error in the console:

An error popup appeared with the following content:

Error in final launch sequence:

In the readme.txt of example I'm found the following:

In order to make the program work, you must do the following:

1. Select required configuration in memory.h in ExtMem_CodeExecution\ExtMem_Boot\Inc. The default configuration is:
   • DATA_AREA set to USE_INTERNAL_SRAM
   • CODE_AREA set to USE_OSPI
2. Program the internal Flash with the ExtMem_Boot (see below).
3. Program the external memory with this application (see below).
4. Start debugging this application or reset for free running.

But I'm unable to find any memory.h in the project and can't understand if anything I need to attach to my project to find this memory.h, edit it, and successfully run the example.

Will appreciate your help

Thank you

Hello @code-by

To load the ExtMem_Boot to internal Flash Could you please erase the full chip using STM32CubeProgrammer and select required configuration in memory.h before loading the project image.

With external memory please use the STM32CubeProgrammer as shown in the readme.txt file. And load the binary application file into the external OSPI flash at the address 0x90000000.

With Regards
