Hi,I'm using F4 series board (STM32F423ZHT6). also I'm using F4 and scripts say L series - are they compatable?STM32CubeProgrammer version: STM32CubeProgrammer 2.14.0 - This is support SBSFUX-CUBE-SBSFU version: 2.6.2I follow the https://www.youtube...
Hi,I'm using STM32F423ZHT6 MCU board. I want to implement the FOTA as well as Scure Boot on my EVAL board. But I don't have much knowledge about Secure Boot. So, I refer https://www.st.com/en/embedded-software/x-cube-sbsfu.html and AN5056. The SBSFU ...
I'm struggling with entering RDP level 1 using the ST Cubemx code examples. I am stuck with OPTVERR bit set and never being successful in getting FLASH_OPTR RDP bits set to 0xBB AND written into flash so that it boots using 0xBB and not 0xAA. (I ca...
Hi, I followed all the steps from the UM2851 documentation about TF-M application. At point 10.2 I ran the regression.sh script, with the below output: regression script started Regression to RDP 0, enable tz -----------------------------------...
Hi,I am implementing the sbsfu encryption functionality on the stm32u575 micros which do not contain hardware accelerator. For this I have decided to use x-cube cryptolib to be able to encrypt and decrypt messages. I have tested the example aes_cbc_e...
Hello all,I'm trying to build B-L4S5I-IOT01A, 2 Images KMS project and I'm encountering the build issue related with missing function definition for KMS_LL_Finalize(). Build fails during linkage phase.Is that issue related with the wrong version of K...
