While programming OptionBytes or FW on STM32WLx5 most of the time is OK.In CubeProg I have noticed, that on some MCUs, when I get reading of RDP 0xFF or 0, the next action to program something write related, it could not be done and it's failed.Stati...
hi all,I would like to experiment with the TFM applications contained in the STM32CubeU5 package on my B-U585I-IOT02A boardunfortunately, it seems that STM32CubeIDE is not supporteddoes anyone have suggestions on how to build the TFM applications, ba...
Hey, I went through the manual of the STM Programmer command line interface and implemented a post build CRC calc with the Safety lib command -sl.C:\PROGRA~1\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -sl MESOL_CAN_...
I am building a custom loader for SBSFU on the STM32WB5MMG. The loader is similar to the BLE_Ota loader, but instead of using BLE, it loads firmware/wireless stack from an onboard microSD card, as well as being able to write CKS keys.I do need to hav...
As I understand OTFDEC will be used to on-fly decryption, while execution (am I correct)?After debug is fused (RDP set to level 2) all DHUK keys are individual for each device, while during debug phase all keys are common. How can I make test run of ...
I set my flash OB to iROT-Provisioned (Dont know exactly Product life cycle state, but I can not debug anymore) Based on my understanding, it may be in a CLOSED state. However, I am not sure how to change the state as I want to follow the Debug authe...
Currently, my program cannot be executed, and it is useless to pull up the boot pin, and STLink cannot be linked. There is a way to reset the chip register boot_lock, TZNE, and RDP? or how to perform full chip erasure?
Hi @ChannelWe are using STM32U585 for implementation of TF-M and TF-M SBSFU for our project. now we are planning to change our controller to STM32U5A5 controller. I have couple of doubtsSTM32U585 is PSA Level3 certified while STM32U5A5 is not PSA lev...
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 UserA...
