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_SERIAL=y

CONFIG_CONSOLE=y

And do below addings

I release and download the .hex to device, but device didn't print "Starting mcuboot\n" in the UART. I'm sure the UART config and hardware part is no problem because when I run direction_finding_connectionless_tx example, it print well. But smp_svr didn't. Now I cannot figure out if the device running well or not because no debug information. Any suggestions for the uart print? Any wrong setting in my above things.

Hi Dejan,

I remove the existing build folder and rebuild again. Yes, I got the updated release .hex. But device still didn't run which means cannot output logs via uart.

It seems that the build process was successful. Could you confirm?

Was flashing also successful? Did you get any errors during the process?

The build process and flash program are all successful. The only problem is that I can't judge if the FW can run normally, because I think it should output logs when device start but unfortunatelly, no any logs print in UART

Hi,

You could try to remove hci_rpmsg and add CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y to your child_image\mcuboot.conf file, and rebuild your project.

Best regards,
