Hello,I am using the stm32u5 SBSFU application and I am trying to implement my own 64 MHz clock. But when I change it from 160 Mhz to 64 Mhz the application does not work. Can the SBSFU clock work with less than 160 MHz or does it have to work only w...
Flash Memory is divided in different zones Secure (also protected by watermark), NCS and NS. All of such zone are defined in the the partition_stm32U575xx.h and SAU is enabled.MCU is in secure mode and want to write in the non secure area.Erasing ret...
I am trying to get application level RDP progression into my bootloader to kind of self protect my firmware once it has started. I have set level 1 and the firmware still runs and I can no longer read out flash or debug, so that's the positive side.B...
Hello,I am using the sbsfu application. Once I have implemented the SBSFU firmware to the board, when I connect the board to the STM32Cubeprogrammer, the SBSFU application is in lock status because it has detected an intrusion. I would like to add a ...
Hello,I've added the OEM2KEY AND OEM1KEY to the RDP Level 2 protection in order to perform the same steps as in the 'Getting started with STM32CubeU5 TFM application' for enabling Production Mode.Following the steps and executing the HARDENING.SH fil...
Hi,[EDIT 3] there is no need to configure GPIOC pin 0,1 and 2 as secure to be used by ADC1 since all GPIO are secure by default when TZEN = 1. cf. RM0456 § 3.5.6 "activating TrustZone security". This is why you do not find an of this in generated cod...
We managed to successfully run TFM_SBSFU example for the IOT02A board. We are using latest STM32Cube_FW_U5_V1.2.0.The problem is that we do not have access to PSRAM from NonSecure application when in memory mapped mode.We implemented PSRAM init by im...
Hello,I am trying to compile the TFM application, but when building the TFM Appli Secure project, it says it cannot find the file tfm_parse_manifest_list.exe and gives me errors because not all the .h files that should be generated by running the pr...
Hello,I would like to use the TFM application on STM32CubeIDE for the B-U585I-IOT02A board but I can't find the application anywhere. Any help?
