Can't run modified nrf51-DK example on custom board

[M]

Hi. I took the ble_central/experimental/ble_app_blinky_c example and modified it for my needs. It works on the nrf51-DK. Now I want to use it on a custom board with nrf51822qfab. I modified the Makefile in the following way:

changed LINKER_SCRIPT to nrf51_xxab.ld, changed the flags to -DNRF51822.

Run make flash_softdevice, and then make flash. And it doesn't work. (The simple blinky example does work) After hours of trying to understand the problem (this is my first time with Nordic), I found this thread . Now I know that the program gets stuck on

SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);

I tried to make the same change in clock settings (like in the thread) but it didn't help... Please help.

Hi. Didn't want to open a new thread, because I have the same issue with a different example. This time it's the "BLE Services, a beginner's tutorial". The code runs on the nrf51-DK but gets stuck (reset?) on the same SOFTDEVICE_HANDLER_INIT line. I use the same linker script as was suggested here and the clock is set to NRF_CLOCK_LF_SRC_RC. What is the problem this time? Thanks.

Did you also changed the size of the FLASH and RAM? The RAM should be 0x4000 (16K) less and the FLASH should be 0x20000 (128K) less (compared to this):

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x5000
  RAM (rwx) :  ORIGIN = 0x20002080, LENGTH = 0x1f80
}

Did you also set the .rc_ctiv and .rc_temp_ctiv in addition to NRF_CLOCK_LF_SRC_RC?
