SBSFU on NUCLEO L452-RE

[ALazo.1]

Hi,

I am trying to implement SBSFU on NUCLEO L452RE board just by copying the project for NUCLEO L432KC (2_images, Y modem protocol) and changing necessary elements (target device, startup_***.s file, UART and led setup).

When trying to download UserApp.sfb file through Y modem protocol I see in debugger (running SBSFU project with all protections disabled) that calling the function SE_SFU_IMG_Read during reading active firmware version (function SFU_IMG_GetActiveFwVersion) changes my variables in SRAM.

Do you have any advice how to overcome this issue or can you just provide me an example with NUCLEO-L452RE board?

Thanks for the support

Hello @Aleksandar Lazović​,

I recommend you checking the X-CUBE-SBSFU, it includes several examples on different boards that you can refer to.

For its integration, Integration guide for the X-CUBE-SBSFU STM32Cube Expansion Package application note and the Getting started with the X-CUBE-SBSFU STM32Cube Expansion Package user manual are at your disposal.

Thank you.

Chahinez.
