Hi,

You could have a look at this unofficial sample - central SMP client DFU.

Best regards,

Hi,

I will be out of the office for the next 2 weeks. In case your issue needs urgent attention, please open a new ticket.

I am trying to implement a logic on nRF52840, to send image file over UART in bootloader mode.
Please can you suggest what needs to be taken care for this.

Note: I don't want to use dependencies like mcumgr.

Thank you

Hi,

You could try with this mcuboot.conf:

CONFIG_SIZE_OPTIMIZATIONS=y
CONFIG_SINGLE_APPLICATION_SLOT=y

# Enable MCUboot Serial Recovery
CONFIG_MCUBOOT_SERIAL=y
CONFIG_UART_CONSOLE=n

CONFIG_MCUBOOT_INDICATION_LED=y

dejans Yes that's correct MCUboot serial recovery works and only LED does not work.
Also I tried to add a UART handler in ncs\v2.4.0\bootloader\mcuboot\boot\zephyr\main.c', but also this did not work.

So any other configuration that I need to take care in order to reflect this changes in the application?
Thank you

Hi,

Is it that MCUboot serial recovery works as expected for you but LED indication does not work?

dejans I am using CONFIG_MCUBOOT_SERIAL from 'ncs\v2.4.0\bootloader\mcuboot\boot\zephyr\main.c' in the application running on nRF52840dk.

And the CONFIG_MCUBOOT_SERIAL is configured to use LED (as shown below)

Also included in mcuboot.conf file (see below)

But the LED doesn't go ON when this application is executed.
Please can you comment here, if something else needs to be taken care?

Thankyou

Hi,

With regard to updating firmware, there is an option for DFU over Bluetooth.

It is possible to send custom commands to SMP server. You would have to make your own command inside user-defined space for commands - please have a look at fmfu_mgmt.c and inside your command you would need to write to the secondary slot. In general, you would need to implement quite a lot, but maybe you could use something like dfu_target.c and stream_flash.c. In general, you would need to have accepting, potentially checking, and writing the data.

Best regards,
Dejan
