[McuMgr] Error : NOT_SUPPORTED during DFU by BLE with MCUBoot

[Julien]

Hi

I am currently to add DFU function on my custom device.

So I had McuBoot, and i would like to make the DFU by BLE.

I follow this link in order to do that https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/smp/mcuboot_smp_ble.

It's works well on my nrf5340dk, i also try to report the DFU on peripheral_lbs samples and still working.

But when i am trying to do the same thing on my custom board, i got this error [McuMgr] Error : NOT_SUPPORTED

I am not using an external flash to do the DFU.

My environment are

-IDE : Visual Studio Code

-Zephyr: V2.4.1

-OS: Windows

-custom Board: nrf52833

Thanks,

Hi Julien,

A couple of questions here to start with as an attempt to narrow down what could be wrong

1. In your previous case you mention that you're testing with a nRF5340DK. Have you at any point tested and verified that you're able to add DFU support to a non-custom nRF52 based board such as the nRF52840DK?
2. You're mentioning 'Zephyr v2.4.1'. Could you clarify if you're referring to 'nRF Connect SDK v2.4.1' or if you're actually using a pure Zephyr environment? 
3. Are you able to compile, flash and run any other non-DFU based samples from the SDK to your custom board?
4. Do you get any warnings when compiling?
5. Are you able to add DFU to your custom board using other transports than BLE? For instance using the UART sample instead? github.com/.../mcuboot_smp_uart

Kind regards,
Andreas

Hi AHaug,

1. Currently my only board are nrf5340, i could test on other board tomorrow

2. Apologize, it is nRF Connect SDK v2.4.1

3. I have not try, but i'm able to communicate with i2c, enable bluetooth and connect to it or connect to other device

4. No warning

5. I have no uart available on my custom board

What meaning the error code 8 on McuMgr?

Regards,

[AHaug]

Noted, thank you for clarifying!

Based on what I see it is related to something that you receive that is not supported, my best current guess is that it's regarding reading the notification that you receive prior to the error message.

After examining the project configuration from https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/mgmt/mcumgr/smp_svr/prj.conf and it's BLE overlay file https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/mgmt/mcumgr/smp_svr/overlay-bt.conf with your configuration it looks like you've not included the following two configurations from the Zephyr smp_server sample. Does enabling these two change anything on your end?

CONFIG_MCUMGR_GRP_OS=y
CONFIG_MCUMGR_GRP_STAT=y

Kind regards,
Andreas

[Julien]

Hi

Trying to add

CONFIG_MCUMGR_GRP_OS=y
CONFIG_MCUMGR_GRP_STAT=y (need to add CONFIG_STATS=y because of depencies)

But still got the same issue.
