Hi Vidar,

Thank You for pointing out the clock source and the linker settings. I have double checked both and it turns out that it was due to misalignment in the linker script.

The values that worked for me are:
FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x2018

Hi,

Seems like you have updated the linker settings since it's only the BLE examples that don't work. The development boards have an external 32Khz mounted, but this is optional. Maybe you don't have this on your board? In that case, you need to change the clock source to the internal RC oscillator, see nrf_clock_lf_cfg_t in ble_stack_init().
