How to debug App + Bootloader

[parco]

Hi all,

I have sent an application ZIP OTA and performed DFU, the log:

...

<debug> app: All flash operations have completed.

<debug> app: Starting reset timer.

<debug> app: Attempting to reset the device.

<debug> nrf_sdh_soc: In nrf_dfu_transports_close

<debug> nrf_sdh_soc: num transports: 1

<debug> nrf_sdh_soc: Shutting down BLE transport.

<debug> nrf_sdh_soc: Disconnecting.

<debug> nrf_sdh_soc: BLE transport shut down.

<debug> app: Reset.

<debug> nrf_sdh_soc: Initializing the clock.

<debug> nrf_sdh_soc: Enter nrf_dfu_continue

<debug> nrf_sdh_soc: Valid App

<debug> nrf_sdh_soc: Enter nrf_dfu_app_is_valid

<debug> nrf_sdh_soc: Return true. App was valid

<debug> dfq_req_handling: Erasing settings page additional data.

<debug> nrf_sdh_soc: Enter nrf_dfu_app_is_valid

But I do not see the device advertising.

I'm wondering at this point how do I debug the device?

Please note I have tested the application with only softdevice and it works perfectly.

Any other suggestions as to why it might not be working when the bootloader is involved?

I have debugged it by merging the application.hex with the settings.hex, and overwriting the debug's target hex with that merged file. Then simply started debugging.

Also, I have narrowed the problem down to sd_ble_uuid_vs_add returning error 4.

0x00000004 is NRF_ERROR_NO_MEM.

You can try to increase NRF_SDH_BLE_VS_UUID_COUNT. This may give you a new error, because the SoftDevice will require more RAM. Have a look at nrf_sdh_ble_enable().
