keil stop hardfault

[Nick]

I'm running example apps from the SDK on a PCA10028. When debugging in Keil uVision, I find that I can only stop the code once. The second time I try to stop the code I always end up at the HardFault handler.

Is this normal? What is causing the HardFault? Is there a way to stop the hardfaults from occuring so I can debug more effectively?

The softdevice interrupts are not handled when the program is being halted by the debugger, which will eventually break the real time requirements of the BLE stack and result in a hardfault. Please see this thread for more details.

ok, thanks
