I have update uImage and dtb but I get this error during boot 

Starting kernel ...

E/TC:0 Panic 'Watchdog' at /usr/src/debug/optee-os-stm32mp/3.19.0-stm32mp-r1-r0/core/drivers/stm32_iwdg.c:198 <stm32_iwdg_it_handler>
E/TC:0 TEE load address @ 0xde000000
E/TC:0 Call stack:
E/TC:0 0xde0030f9
E/TC:0 0xde019f87
E/TC:0 0xde00c873
E/TC:0 0xde01966d
E/TC:0 0xde039601
E/TC:0 0xde000340

After this kernel could not start? what is the issue?

Hi @stack_shailesh 

Please refer to How to debug OP-TEE - stm32mpu and particularly the "3.3 Stack unwind support" and related abort-dumps tool.

It will help you to narrowing the problem.
