Zephyr basic program is not running after flashing on STM32H563ZI

[AravindS-Danlaw]

Hello,
I'm trying to build blinky program and flash it to STM32H563ZI , were build is done using west build -p always -b nucleo_h563zi samples/basic/blinky command and flash is done using west flash. Looks like flash is successful but no LED is blinking. The flash status is attached below for reference.

Also tried building hello world program and flash it, Similarly build and flash is successful but no prints were seen in UART serial.

Any idea on what to do next or how to debug.

FYI, tried west debug and got no luck.

If you're building from arm64 host i encoutered an issue with picolib included in sdk. Try adding CONFIG_PICOLIBC_USE_MODULE=y. Solved the issue for me.

The above issue was solved when the clock source was changed as highlighted in below image,

But the blinky code still exits here in the highlighted place

Does this requires any configuration updation in the dts file.
