Implementation of TFM_SBSFU on STM32U585

Hi All,i have downloaded the STM32U585 firmware package from the official sources and want to implement the TFM SBSFU program code into my development board(U585-IOT2A) using STM32 Cube IDE. The user manual mentions installation not possible using Cu...

Resolved! Unable to reallocate Application at other than base address

I aim to load my application at 0x08002000 instead of 0x08000000(base address) and secure the first two sections which will be used to store CRC and other firmware update information.I use a post-build script to calculate the CRC using srecord utilit...

Resolved! possible bug in F3xx Firmware?

When I compile a simple programm, using the CRC feature I get the following warning:In file included from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_def.h:30, from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_rcc.h:29, ...

Resolved! AIRCR.PRIS = 1 / PRIMASK_NS=1 Higher priority secure interrupts are disabled

Hi,I'm playing with Nucleo-u575zi and GPIO_IOToggle_TrustZone example.Everything is working as expected.I want to be sure that systick of secure zone is never blocked by nonsecure zone (e.g. setting PRIMASK_NS =1). In secure mode, at startup, I then ...

Hi, I want to do regression with USB(DFU) mode. Please advise how to modify: regression.sh in "STM32Cube_FW_U5_V1.0.0\Projects\TFM_SBSFU_Boot\STM32CubeIDE". Regards, QiZhang

WRITE_REG macro not working

I'm currently trying to use the CRC peripheral on an STM32G474, and when running HAL_CRC_Calculate(), the computed checksum is always zero. Doing some debugging into the HAL_CRC_Init() function, I've found that when the WRITE_REG macro is called, no...

STM32Cube_FW_WL_V1.2.0, application LoRaWAN_SBSFU_1_Slot_DualCore. Bug in the MPU configurations??? (file .\2_Images_SBSFU\CM4\Inc\sfu_low_level_security.h)

I'm creating a new lora project starting from STM32Cube_FW_WL_V1.2.0, application LoRaWAN_SBSFU_1_Slot_DualCore.I reserved some space (from 0x0801A000 to 0x0801BFFF) for some configurations. I modified the file mapping_fwimg.ld like below.\STM32Cube...

STM32CubeIDE support for TFM Application ?

I wish to try the TFM application on my B-U585I-IOT02A demo board. But the support for STM32CubeIDE has disappeared in FW_v1.1.0. Is there any reason for that, or can I copy the project from patch_cube5_v.1.0..2, though the source files have signific...

Resolved! Warning in HAL CRC since updating to F0 Cube v1.11.3

The clear_bit macro in the CMSIS driver is causing a warning when used in the function HAL_CRC_DeInit:

Resolved! STM32f030k6 CRC Config error

I want to use CRC on STM32f030k6, but as soon as I enable it, some errors appear and compilation fails.Even when I want to use EEPROM Emulation example for the above micro, again it fails to compile.What is wrong?STM32CubeIDE - Version: 1.10.1STM32Cu...
