Hi,
I am trying to toggle LED in FreeRtos task by enabling TrustZone in STM32cubeIDE .
I toggled LED in Non secure region.
When I did the debugging . it’s going to Infinite loop in the function prvInitialiseNewTask .
I used the default task given from STM32cubeIDE.
Hi Gaurav,
Thanks for replying to my post.
I want to use FreeRtos task exclusively in Non-secure region.
But due to some issue in STM32cubeIDE .I should enable Rtos in both secure and non-secure region.
Hence there are two FreeRTOSConfig.h for Secure and Non-Secure.
I am attaching both the files.
This is my Non-secure FreeRTOSConfig.h file

You likely are running FreeRTOS on the non-secure side. When you run FreeRTOS on the non-secure side, you need to run a small secure context management component on the secure side as well and that is why you see 2 FreeRTOSConfig.h files.
Hi Gaurav,
As suggested I commented the line #define SysTick_Handler xPortSysTickHandler and compiled.
I am still facing the same issue .
when I did the debugging from the function osKernelStart() In function prvInitialiseNewTask()
it’s going to the infinite loop.
Also is there any link how I can use FreeRtos for Secure and Non-secure in STM32CubeIDE
Hi Gaurav ,
I am very new to FreeRtos concept , I did not understand what do you mean by “install a different ISR for all the interrupts in the startup_stm32h563zitx.s file”
Can you elaborate on what I should do .
Forgive me if this has been already covered, but I see that the signal is received within a call to memcmp(), and the default interrupt handler is then invoked. The default signal handler contains Infinite_Loop.
Is it possible that there is a memory access violation or some other out-of-bounds addressing issue?
[edit]
Looking at more of the thread, I also see memset() and memcpy(); my guess is that the stack address that is being used is invalid in some way, leading to an attempt to access non-existent memory.
Hi Gaurav,
Thank you for replying to my post .
I am not able to attach .s file so I changed the same startup_stm32h563zitx.s file extension to .c and attached.
Non secure startup_stm32h563zitx.s startup_stm32h563zitx.c (17.9 KB)
Nonsecure-main file
You’ll see that in this file, there is a vector table g_pfnVectors which has entries for all the ISRs (for example, WWDG_IRQHandler). You will also see that all the ISRs are currently defined to Default_Handler in the lines looking like the following:
Please read my message. You need to follow the same pattern for each ISR. In other words, do what you did for WWDG_IRQHandler for all the following ISRs:
