SMP DFU function by uart in NRF52820

[Treacy]

Hello guys,

I want to test SMP DFU function by uart. I use "E:\Spec\bluetooth\Nordic\nRF52820\ncs2.5.0\v2.5.0\zephyr\samples\subsys\mgmt\mcumgr\smp_svr" example and add below Macro in prj.conf.

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y

# Enable the serial MCUmgr transport.

CONFIG_BASE64=y

CONFIG_MCUMGR_TRANSPORT_UART=y

CONFIG_CONSOLE=y

But project cannot build successfully. See below problems. How can I solve this problem? Any operations I did wrong?

Hi,

Please check that the uart node is enabled "status="okay";" in your devicetree (overlay) and that CONFIG_SERIAL=y is defined in the prj.conf  file (you can check actual value of Kconfigs in file build/zephyr/.config).

The suggestions in this post might be useful to debug this kind of error.

Best regards,
Jørgen

Hi,

Thank you for your response. I've done all the things you metioned, but still cannot build successfully.

1. I checked the uart node, it is already "status="okay". See below screenshot

2.  CONFIG_SERIAL=y set too. But "CONFIG_SERIAL=y CONFIG_CONSOLE=y"  seems are different from other Macro.

3. when build finish, there is nRF52820/ncs2.5.0/v2.5.0/zephyr/drivers/console/uart_mcumgr.c:254: undefined reference to `__device_dts_ord_82' error. So I do the troubleshooting as "this post", add "status = "okay";  "in &flash0 part, but still cannot build success

4. I list all my changes based on the example. Please do a check

I'm really looking forward to your reply.

BR,
