CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU doesn't work with SPI NOR

[Rbouteiller]

Hi,
The Kconfig fragment  CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU is awesome to quickly get BLE OTA working.
However, when going in depth, we can see that it's implying:

imply NORDIC_QSPI_NOR if $(dt_chosen_enabled,$(DT_CHOSEN_EXT_FLASH))

This make the kconfig not works with external simple spi.

The fix is to manually put all lines of the fragment (except the QSPI one) in prj.conf

CONFIG_MCUMGR=y
CONFIG_NET_BUF=y
CONFIG_ZCBOR=y
CONFIG_CRC=y
CONFIG_MCUMGR_TRANSPORT_BT=y
CONFIG_MCUMGR_TRANSPORT_BT_CONN_PARAM_CONTROL=y
CONFIG_MCUMGR_TRANSPORT_BT_AUTHEN=n
CONFIG_IMG_MANAGER=y
CONFIG_STREAM_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_FLASH=y
CONFIG_MCUMGR_GRP_IMG=y
CONFIG_MCUMGR_GRP_OS=y
CONFIG_MCUMGR_GRP_OS_BOOTLOADER_INFO=y
CONFIG_MCUMGR_TRANSPORT_BT_REASSEMBLY=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=y

Maybe it's possible to change the QSPI inclusion ?

Thanks

Hi,

This is a bug, unfortunately. I have reported it internally, and I hope it can be addressed in time for the next SDK release. I do not see a clean way to override the NORDIC_QSPI_NOR symbol from the parent image.

Best regards,

Vidar

hello, I experienced the same issue. In which SDK version was this bug fixed?

[Vidar Berg]

Hello, 

This line was removed in SDK v2.8.0: https://github.com/nrfconnect/sdk-nrf/commit/318644b2dcc2aa67aefd35a2738c59b304be7e3f

I'm currently using SDK v2.7.0 and have no plans to update it yet. So, can this be resolved by simply commenting out the line imply NORDIC_QSPI_NOR if $(dt_chosen_enabled,$(DT_CHOSEN_EXT_FLASH)) ?

[Vidar Berg]

Yes that, or configure FOTA support without using the CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU symbol like OP did.

Alright, Vidar, thank you for your help.

Best regards,
