Hello,I am using the STM32U575ZIT6 microcontroller and have created a simple TrustZone project where all applications run in the non-secure zone. However, when the program attempts to switch to the non-secure zone, it triggers a hard fault handler er...

Hello,I am trying to make a program in which the micro stm32u5 is stored in ram memory some data after activating the Sleep Mode.For this I have defined in the flash file the SRAM2 memory that is supposed to be in charge of this and I have saved it ...

Hello,I am working with SBSFU on a STM32U575 microcontroller and have written a function to check the cause of the system reset by reading the flags from the RCC registers using __HAL_RCC_GET_FLAG. However, the issue is that none of the RCC register ...

Hi,I am working with SBSFU on a STM32U575 microcontroller, and I want to use the __attribute__((section(‘.ram2’))) to place a variable in the secure SRAM2 memory section so that the variable can write to it. However, the secure SRAM2 memory is reset ...

Yes, I have configured the flash byte watermark option but instead of 0x7f in SECWM2_PSTR I have set the value to 0x1

Hello @Jocelyn RICARD,Just following up on my previous question about the function I implemented to read the reset flags from the PWR and RCC registers. It keeps returning "unknown reset" every time I run it. Any idea why this might be happening?

The problem was that I was using the stm32u5xx_hal_timebase_rtc_alarm_template.c library, and a part of the code triggered a forced reset of the memory.

Hello @Jocelyn RICARD , I know that the register will not going to be one but using the following function that I’ve implemented to read the reset flags from both PWR and RCC registers to determine the cause of a system reset. However, every time I r...

Hello,I made a mistake with the memory address which was SRAM3 0x30040000 with 0x300D0000. With 0x30040000 it works perfectly.
