application stops at sd_nvic_EnableIRQ(SWI2_IRQn)

[Tarik]

Hi, My application always stops at the end of ble_stack_init() exactly at:

return sd_nvic_EnableIRQ(SWI2_IRQn);

of the function softdevice_handler_init.

My board does not have a low frequency external oscillator this is why my clock source is set to "NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION"

What SDK and SoftDevice version are you using?

[Tarik]

SDK v 6 and s110

If you see here, someone had the same problem as you with sdk 6 and s110, they solved problem with upgrading to a newer version of SDK/SD. Do you use sdk v6.1 and S110 v7?

[Tarik]

Newer versions of the code are always bigger than the 32Kb limit of free Keil, and it never works when I compile them using GNU on eclipse and I never managed to get debugging to work on eclipse.
