Hi all,We have been testing our 2 images configuration SBSFU firmware update with our NUCLEO-L476RG. We have encountered 2 scenario's during which the different steps taken by the bootloader was not entirely clear to us. We could use your help to cla...
Hello,I am trying to mimic the STM32 Example code, UART_Trace_TrustZone, to have my nonsecure world use a secure callback to print to the serial port after being initialized. However, only my secure world prints to the serial port. Ideally, I would a...

Hello,I need help setting the secure memory area for the STM32H753XI mcu. I am running it on STM32H753I-EVAL kit.I have read the dedicated part on the reference manual (chapter 5 on document RM0433), the "Introduction to STM32 microcontrollers securi...
hi there I cannot figure out the true meaning of htcr reg and config1~config3 field in rng_cr reg。 I was wondering about the relationship between health test register and health test parameter （repetition counter test the “40�? consecutive bi...
Hello,I have an unexpected behavior with a H753ZI board. After a very few steps, I ended up in a situation where PCROP seems to be enabled and RDP level is set to 0. For some reasons, this causes the board to freeze indefinitely, moreover after disco...
