nRF5 SDK 16 BLE startup, failing nrf_atfifo_item_alloc

[Jed Marti]

During BLE startup call to nrf_sdh_enable_request(), nrf_atfifo_item_alloc fails and returns NULL causing a hard fault.

This sounds like an sdk_config.h problem but I don't know where to start looking.

I assumed you were working with a standalone application with everything running on the nRF52 device, not a  "serialized setup" with the app code running on a different CPU. Has the application been ported to a different platform (ie not a nordic nRF device)? The atfifo assembly is written for the Cortex m4 architecture.

This is running on an nRF52832 standalone. I'm running the SEGGER IDE (Linux version) JLINK base programmer talking to the board. I don't have a BLE application (phone based) yet, just using nrfconnect but if I can't get bluetooth started, the app is  meaningless. Is the 52832 not an M4 device?

Am I using the wrong bluetooth code? This was setup to use softdevice S112.

I see. Your project is not set up correctly then. Some of the function calls you listed in your previous response are only used for serialization (ser_app_hal_hw_init, ser_sd_transport_open,..) so that is why I got confused.  I suggest you start with an existing SDK example such as ble_app_blinky and verify that it runs on your board.
