I made a custom board
And I am running the segger example ble_app_blinky_pca10056_s140
But
Even if I run log_init();, it returns error code 5
And even if I run timers_init();, it returns error code 5
If I comment out all the codes and only control the GPIO toggle, it works without any problem
I am using the sdk version nrf5_sdk_17.1.0, I am using nrf52840 revision 3
Can you tell me what is causing this problem?
Thank you
