Change register on action (run, stop, breakpoint) hook

godmode · Oct 12th 2017, 3:39pm

Is it possible to execute a script on specific action like breakpoint, stop and run?
I'm writting soft for nRF52832 using Nordic Semiconductor nRF52 SDK.
The chip is programmed with so called softdevice a closed-source software which uses interrupts and co-exists with my appliacation.
Every time I need to break I need to change register PRIMASK (Cortex-M4) to 1 to suppress interrupts just before the breakpoint.
That is the only way to debug without hardfault - one step after the breakpoint.

So is it possible in Segger Embedded Studio to configure a hook to execute change in a register on a breakpoint?

Hello Maciej,

Sorry for the delay in response.
Thank you for your inquiry.

This is currently not possible.

In such a case you can use the monitor debug mode that Nordic devices support.
