sd_softdevice_enable() Hanging on Custom Board

[phipi]

I'm trying develop on a custom board based on the nRF52832 and am running into some issues. When I run the blinky application (with no SD) the application executes fine. However when I try to run the ble_app_blinky application it hangs (no return) when trying to execute the below line:

ret_code = sd_softdevice_enable(&clock_lf_cfg, app_error_fault_handler);

I am using custom hardware with no external LF clock and have made the changes to the application (though I've left the original bootloader) as described here:

I'm not 100% sure I have the IROM and IRAM settings correct. Could a hardware issue cause the sd_softdevice_enable to hang? If no, what else can cause it to. If yes, then what should I be looking for?

My setup is as follows:

nRF52832 QFAAB0

SDK14.2

SD S132 V5.0.0

IROM Start = 0x23000 Size = 0x5D000

IRAM Start = 0x20002180 Size = 0xDE80
