Application stops when executing prvPortStartFirstTask for CM4

In the capture, you can see also the VTOR address it’s 0xe000ed08, is there somewhere else where i can check it ?

Hi @Zak ,

The address of the VTOR register is 0xe000ed08, but the value is 0 as shown in either hex or binary column. After taking svc 0, mcu is jumping to the address stored in VTOR register which is 0.

@Zak

I have put breakpoint in “vPortSVCHandler” function also, but it never reach it

It does seem like VTOR is not properly. Because, as per the picture above, value at address 0x0 is 0xffffffff. Can you please check the address where the exception vectors are located either from the.map or the linker script and load that value into VTOR by following prvPortStartFirstTask() fails at SVC 0 - Kernel - FreeRTOS Community Forums ?
