Interrupt vector reuse

[bobobo]

I have some problem with Interrupt vector,details as below.

I design a bootloader code,and in the bootloader,i use timer0 interrupt.Then in the app code,i use the timer0 interrupt again,but when debug the app code,some problem happened when the app code call the timer0 interrupt irq handler. I guess maybe the right timer0 interrupt irq handler is in the bootloader,but how can i reuse the timer0 interrupt in the app code again. Thanks for reply!

Are you by any chance using a Softdevice in your application? Timer0 is blocked by the Softdevice and if you use it your app will crash. Here is a list of blocked peripherals: System on Chip resource requirements.

I use bootloader without softdevice, it was designed by myself,and i'm use nrf51822.The bootloader start from address 0x00000000, and the application start from 0x00002000.In the bootloader,i use timer0 interrupt,and in the application, i also use timer0 interrupt.

What exactly is the problem that happens when the app code call the timer0 interrupt irq handler?
