DFU with nrf connect 2.4

[lvh831]

Hi Team,

I followed the DFU tutorial from https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#other_dfu_samples using ncs 2.3 and it works fine. When I switch over to ncs 2.4, I got errors for missing symbols:

warning: attempt to assign the value 'y' to the undefined symbol MCUMGR_CMD_IMG_MGMT

warning: attempt to assign the value 'y' to the undefined symbol MCUMGR_CMD_OS_MGMT

warning: attempt to assign the value 'y' to the undefined symbol MCUMGR_SMP_BT

warning: attempt to assign the value 'n' to the undefined symbol MCUMGR_SMP_BT_AUTHEN

Are these symbols removed in ncs2.4? Is there an update document for DFU using ncs2.4? Thank you so much.

Hi,

Yes, MCUmgr Kconfig option names have been standardised in this release. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/releases/release-notes-3.3.html#libraries-subsystems

MCUMGR_CMD_IMG_MGMT -> MCUMGR_GRP_IMG

MCUMGR_CMD_OS_MGMT -> MCUMGR_GRP_OS

MCUMGR_SMP_BT -> MCUMGR_TRANSPORT_BT

MCUMGR_SMP_BT_AUTHEN -> MCUMGR_TRANSPORT_BT_AUTHEN
