Hi all,we are developing a product with the STM32H573. The idea is to use the STiRoT for secure firmware update. The MCU is connected to a Linux CPU via SPI. Now we plan to do the provisioning during the production using the Linux CPU that has a ethr...
I am using USB peripheral on the STM32U5 with TrustZone enabled. I met a problem. In Non-Secure area, USB_DRD_FS->CNTR, USB_DRD_FS->CHEP0R can be set correctly. In Secure area, I can set "USB_DRD_FS->CNTR = 0x9D00;".But I can not set the "USB_DRD_FS-...
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 ...
I'm using an STSAFE-A110 chip with SPL02 profile on a custom board and trying to get StSafeA_WrapLocalEnvelope() function working. I've already successfully paired my chip with my MCU/FW by writing the default host MAC key from the ST examples to the...
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...
Hi @Jocelyn RICARD Greetingswe are trying to run TFM example (with secure and non secure project) taken from GPIO_Toggle_TZEN Example and adding SPI communication in the non secure project on our custom board mounted with STM32U585aii6q controller SP...
Hello,I'm trying to figure out how to properly use STM32WB55 PKA registers for RSA key generation and encryption/decryption. I have chosen small (63 bit) primes for generating RSA private key, which worked perfectly. However, I am having trouble with...
Hello ST Community,I'm currently working on a project using the STM32WB55 MCU and am in the process of implementing Secure Boot and Secure Firmware Update (SBSFU) in my custom application. As part of this, I decided to test the existing 1_Image_SBSFU...
Hi ,i am using STM32L4R9 based dev board STLINK-V3MINIE and wanted to use SBSFU, used the example code STM32L432KC_Nucleo_1_image from the library and flashed the SECoreBIN followed by SBSFU and then the userAPP code, but while flashing userAPP ,i go...
