What is error ?

[Giang]

Hi all , when I run and debug my code , I frequently encounter error :

I think it's related RAM configuration on KeilC . Please show me what is error ? And how to solve it . Thank very much !!!

debug my code

Once the softdevice (SD) is enabled, you cannot use breakpoints (or watchpoints) any longer, since these will halt the CPU core. This triggers internal timeouts in the SD - the error condition ends up in the app_error_fault_handler() function. The id and pc arguments may hold some information.

You may want to check the call stack - with a wrong RAM configuration this might get called early and not always from within the SD.
