Possible SIGTRAP in Softdevice S140

[patric]

Hello,

We are currently in the progress of porting a project from the nrf52840dk reference board to a custom board and are having some issues during initilization.

Setup is using Softdevice S140 7.2.0 and nRF52 SDK 17.1.0 using secure_bootloader

On the nrf52840dk we can flash and get RTT logs without issue but when flashing to the custom board we get a SIGTRAP before the bootloader main() that seems to be located in the softdevice.

Any advice or hints where to continue digging?

The reason seems to be that nrf_memobj_alloc() in nrf_log_frontend_dequeue() returns NULL

This happens because

if (p_pool->p_cb->p_stack_pointer > p_pool->p_stack_base)
in
nrf_balloc_alloc() fails

p_stack_pointer = 0x20002953

p_stack_base = 0x2000926c
