mcuboot enter with button

[William.wei]

hi support team，

i was testing smp_svr, i want to add button to my application that once i press the button and reset, the device will stay in mcuboot (serial port mode)and i can program my device with serial port, liking our old sdk bootloader----examples\dfu\secure_bootloader\pca10040_uart , how can i accieve this function?

it it more like how our thingy53 works.

 i don't know how to add button or gpio to my project.

Thanks!

Regards,

William.

Hi,

Sorry Siguard,

i was testing nrfutil device program --firmware command. for now i am able to upgrade thingy91 as documents described.

the documents is : One tool to rule them all: nRF Util becomes a unified command line utility 

but, when i was testing 52840 peripheral uart, i am not able to upgrade 52840 with serial_recovery mode in mcuboot, or smp over uart in application. i don't know if it was code problem  or our tool is only supporting thingy91?

however for the mcumgr, i can upgrade successfully. i don;t know the difference.

Regards,

William.

nrfutil is searching for VID and PID of the device to match a pre-set number of PIDs.
So you have three alternatives

• Use another tool for the programming. See here for a list
• add PID and VID to your nRF52840
• nrfutil device x-execute -o program --args 'firmware[file]=./dfu_application.zip' --device-filter 'serialNumber=4254EFB4D8746FF6' --override-traits mcuBoot --inject 'mcuBoot[vcom]=0

Hi Sigurd,

 i was still not able to program device as below: however mcumgr is working after nrfutil device program fails

C:\Users\William>nrfutil device x-execute -o program --args 'firmware=C:\ncs\v2.6.0\test\peripheral_uart\build\zephyr\dfu_application.zip' --device-filter 'serialNumber=683014854' --override-traits mcuBoot --inject 'mcuBoot[COM23]=0'

it is really hard to findout what's wrong in my command.

snr 683014854 should be correct as i can select this jlink to program:

C:\ncs\v2.6.0\test\peripheral_uart>west flash --recover --snr 683014854
-- west flash: rebuilding

If the command does not work, i think I will just suggest that you use one of the other tools for now.

I spoke to our nrfutil developers, and it does not officially support SMP yet

Hi Sigurd,

it doesn't make any sense.

For assert_tracker_v2, with borad thingy91 it is working now. 

how does this command work?

C:\Users\William>nrfutil device program --firmware C:\ncs\v2.6.0\nrf\applications\asset_tracker_v2\build\zephyr\app_signed.hex --traits mcuBoot
[00:00:01] ###### 100% [5/5 THINGY91_F6ABB02220E9] Programmed

and it is clear that we can program device with mcuBoot:

The Thingys has the PID and VID set correctly. See here.

The sentence means that we support MCUboot programming with nrfutil, but only for a subset of our devices (which have specific VIDs and PIDs).
We do not yet support detecting other devices with SMP enabled. I asked about this in https://nordicsemi.atlassian.net/browse/NCSIDB-969, and got to know that it was not supported yet.
