Hi ,

I am working on STM32F415RG, I recently wrote a bootloader program, which is doing its job of jumping to a specified location. 

Now my bootloader(at addr

0x08000000

) is able to jump to my main application(at addr

0x0800C000

 ), but when I see my main application getting executed I noticed it doesn't execute completely. It stops at the very first HAL_Delay(10) statement and hangs rest of my main application. 

Can anyone please help what went wrong?

Make sure you set up the vector table (SCB->VTOR) to point to the new table base.

Don't call the application code from within an IRQ Handler, or interrupt state.
