Can't copy vector table to RAM when using softdevice

[MBRT]

I am using IAR workbench and working with the nrf52 DK, using the S132 v.3.0 softdevice. I used the blinky example code to connect the nrf52 with my android phone over BLE. To configure interrupts @ runtime I copy the vector table to RAM. When I do this I can't connect with the nrf52 anymore. Every time I try to connect the application crashes and the stack pointer goes to address 0. I thought the "sd_softdevice_vector_table_base_set" function could offer a solution but it doesn't work. The vector table is also still available in program memory.

In a previous project, using the nRF51, it wasn't a problem copying the interrupt vector table to RAM and using the softdevice.

Hi,

How to you try to forward the vector table when it does not work? And to which address?

Thanks for the fast response but I already solved the problem. I use the AppTimer module which uses SWI0. I didn't copy the interrupt handler for SWI0 to RAM. This results in an infinite loop of recursive calls and by consequence a stack overflow.

I see. Thank you for letting us know.
