Hello,Can we run STM32CubeU5 TFM Application (UM2581) on U575 since it has not crypto hw like U585?Thank you in advance!Best Regards!
Resolved! debug OEMiRoT-Boot project on U083 possible?
I'm aiming to use the OEMiRoT sample project as a concept for secure updating of a large single-slot application in STM32U083 (need application size at least 160kB for migration from STM32L071). For that I need to give the bootloader a driver for ext...
STM32L4A6 with SBSFU and external flash
Hi,I'm trying to get started with the SBSFU (2.6.2) on my custom board running an STM32L4A6. I've got a large external SDMMC flash chip (4GB) connected to the STM32 that I use for user application purposes. I'd like to allocate a small section of t...
Resolved! STM32H753 SBSFU unable to transfer application firmware
Hello.I'm having trouble transfer the UserApp to SBSFU. Here's the description of the issue. Any help is appreciated!I prepared the NUCLEO-H753ZI board by disabling all the security and fully erase the board (by setting RDP level 1->0 ).I'm using the...
STM 32F4xx - what hacks are known around Level 2 security?
It seems perfectly possible, under Level 2, to have a "boot block" which accepts a firmware block (say via USB MSC or via HTTP), encrypted with a key stored in the boot block, and you have a product whose firmware can be upgraded but can't be extract...
Problem with ST cryptographic library (CMOX) AES CBC encryption
We are doing updates on a project which uses STM32H747 and ST cryptographic library (CMOX) / X-CUBE-CRYPTOLIB. It encrypts and decrypts data using these two functions:cmox_cipher_encrypt(CMOX_AES_CBC_ENC_ALGO, ....cmox_cipher_decrypt(CMOX_AES_CBC_DEC...
RDP protection code for STM32H563IIK6
We are using the STM32H563IIK6 in our Device.I want to Enabled CRP protection. We are thinking use Level1only. Please can you share any test code.
OSPI_NOR usage with SBSFU (B-U585I-IOT02A)
Hi, I've decided to create a new post based on the similar one (https://community.st.com/t5/stm32-mcus-security/solved-stm32u5-tfm-example-b-u585i-iot02a-memory-mapped-psram/td-p/108722) which has been solved but doesn't work for me.The problem is as...
