How to Load demo code in STM32L562E-DK board after Executing TFM_UPDATE.sh

[PYada.1]

Hello,

I am using the STM32L562E-DK board. I have tried the Secure boot example located in "STM32CubeL5-master\Projects\STM32L562E-DK\Applications\TFM". I have followed mentioned steps in the readme.MD file. Now I want to load the default demo binary provided by "https://www.st.com/en/evaluation-tools/stm32l562e-dk.html#documentation" > STM32L562E-DK compiled demo binary But I am not able to program it using STMCube Programmer. The programmer log is as follows.

Please help to flash demo firmware.

Hello @PYada.1​,

Check your USB cable, connectors.

You can try to connect in "under reset" mode, or get the device into bootloader mode, then connect the debugger.

Try by connecting to bootloader setting on RSS : BOOT0 to VDD.

Otherwise, please refer to this post, it may be helpful.

Hope my answer will solve your issue!

Thanks to @Imen DAHMEN​  FOr quick response,

FYI, the TF-M application is working as expected. my goal is to run the normal application without a trust zone.

I have tried it, but it is not connecting randomly. I can connect the board using Cube programmer in hot-plug mode.

As per your suggested post, I have changed the RDP level to 0xAA. But still, I am not able to program my normal application.

I am attaching the log of the CUbe programmer for reference purposes.

From the log, it seems that flash is write-protected and because of it, I am not able to flash program(primary assumption).

Is there any script or method available that reset all secure protection and mass erase it or switch from demo TF-M firmware to without bootloader application?

After a certain retry, I was able to do mass erase but after that, I am not able to connect it with the Cube programer

I have tried to check the RDP level using the following command but I am getting errors.
