Hi, I am going through the firmware protection hands on in Part 4 of the STM32 Security MOOCs located here :https://www.youtube.com/watch?v=RahlfYJ1gDs&list=PLnMKNibPkDnF0wt-ZI74SflnsBV4yKzkO&index=5&t=782sThe instructor in this hands on asks to spec...
HW: NUCLEO-H563ZIHello, can someone explain the following behavior to me? Is this a bug or am I using the HAL incorrectly?Thanks a lot. Code snippetThe resultThe result is correct, but the behavior is strange. I receive two error callbacks also.First...
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...
Good day!I am working with the STM32H753 product. I am trying to understand the sequences and state machines for RSS activation. The reference manual (RM0433) does not provide enough information to grasp the full picture. Additionally, there are no e...
I am Missing the Option Security>RNG in my the .ioc tool. Does the F446RE does not have a RNG?i experience identical problems to Implementation of ECC on STM32f446 (Page 1) — wolfSSL — wolfSSL - Embedded SSL Library
Hi,When trying to run a simple TrustZone+UART project generated by STM32CubeMX, the chip raises a HardFault when switching to NonSecure mode. In the HardFault handler, the Cortex-M33 CFSR registrer is set to 0x400, indicating an instruction bus error...
Hello,We have a cybersecurity requirement to protect against unauthorized firmware uploads during data load operations or shop load using JTAG. Is there a feature available in the STM32F7xxx family Microcontroller that complies with cybersecurity sta...
Dear community,where can I find the source code for this generated MX66UW1G45G_STM32H7S78-DK_XSPIM1-SFIx.stldr file?I need to load binary files on an sd/emmc flash passing through the OEMiRoT boot that loads the specific external loader I want to imp...
Hello happy taxpayers[EDIT #1]I forgot to say that what is really working is that is, from non secure app, I try to write in secure SRAM, then I end in the secure fault handler of my secure app. So, in this direction it's really clear the expected be...
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...
