Custom Bootloader jump to application and vice-versa are failing

[Sridhar]

I am trying to develop a custom boot-loader on Nucleo-H743ZI2 evaluation board. But the boot-loader is not jumping to application code. I had referred to the other posts regarding the topic and adopted some code from those also. I had flashed the codes of application and boot-loader to the respective memory locations at 0x8020000 and 0x8000000.

Please do point me to the problem in the code provided.

Do the switch between user and bootlaoder as early after reset as possible. That works for me and many others.

Thank you, it had worked. I had changed the bootloader and application to maximum frequency.
