sd_softdevice_enable hardfault

[Fabien Comte]

Hello,

sd_softdevice_enable falls in hardfault. I have no 32.768 KHz crystal but is set lfclk with NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM.

I'm running my application on a custom board with a nRF52, S132 SD 2.0.0 alpha 7, jling debug over nRF52 DK.

What can i check please ?

you cannot call softdevice SVC function calls from the interrupt priority higher than SVC.

See this thread for more info.

My GPIOTE_CONFIG_IRQ_PRIORITY is already configured with APP_IRQ_PRIORITY_LOW

Can i test / check anything else ?

.. but you're calling it from an interrupt handler? Check the actual value of the IRQ priority you are running at when you call sd_softdevice_enable(), remembering that the IRQ available priority values are different on the nRF52 than the nRF51. You should be able to see that in one of the status registers.

If that doesn't give you the answer, then you look at the stack and figure out exactly where you came from.

No it's in my main. I have a breakpoint later but never gone there. When i do a pause with segger debugger it says that i'm in HardFault_Handler in sd_softdevice_enable.
