STM MCU with Security features and good timing response for communication protocols
Hi, i am looking for a small MCU with ARM trust zone, ROT, SFI and other security features similar to STM32L552.also fast SPI timing req similar to 401 family ( 401 reference only for timing)STM32F401CBU6, does not have the mentioned security feature...
R4 register corruption in STM32L562(ARM Cortex M33) when switching from secure to non secure mode in STMCubeIDE
On switching from secure to non-secure mode using a function pointer (with the cmse_nonsecure_call attribute) in STM32L562(ARM Cortex M33), general purpose registers R0-R4, R12 and floating point registers S0-S15 are not restored when back in secure ...
How to program stm32L552 using SWD interface
I use my own application to program different devices, arm in particular. Now, i'd like to support stm32L552. So, if TZEN = 0 it works fine. if TZEN = 1, DBANK = 1, SECWM1_PSTRT - set as secure, SECWM2_PSTRT - set as non-secure, RDP = 0xaa (level 0) ...
Resolved! Using Trusted Firmware-M on STM32U5 / STM32L5, building my own non-secure application and interact with TFM.
Hello,I want to use the security features included in the TFM in my application, I have followed UM2851, now,I have a better understanding for TFM and I succeed to implement it in STM32U585, to go further I want ot implement my own non-secure applica...

TFM and hardfault with NonSecure application
Hi,We are currently using an stm32l5 in our product and experimenting with a stm32L562E-dk and with the official TFM (https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git master branch on the latest commit at this date.) The TFM is unmodified...
Resolved! Serial DFU of Secure Firmware Fails
I'm attempting to use the serial bootloader to load a secure firmware image to an STM32L5 using STM32CubeProgrammer. I can successfully connect to the board in bootloader mode and perform a full-chip erase, but attempting to download the image (eithe...
