Xenon bootloader update from 0.5.0 to 0.6.1 not working?

ScruffR commented 3 years ago

Set up

Particle Xenon
Windows 10 (21H1 Build 19043-1202)

SW on the device (bootloader mode)

UF2 Bootloader 0.5.0 lib/nrfx (v2.0.0) lib/tinyusb (0.9.0-22-g7cdeed54) lib/uf2 (remotes/origin/configupdate-9-gadbb8c7)
Model: Particle Xenon
Board-ID: nRF52840-Xenon-v1
SoftDevice: S140 version 6.1.1
Date: Apr  4 2021

Describe the bug

I did expect that I can replace the current bootloader by putting the device in bootloader mode and copying the update-particle_xenon_bootloader-0.6.1_nosd.uf2 file to the device. However when the device comes back ist still reports bootloader 0.5.0

Is it not supposed to work as UF2 upload or is that file incompatible with the Xenon?

it should work as other boards, but I don't have a xenon to test with.

@hathach , thanks for the reply :+1:

So you also think that my process was correct and should work?

plug in device
put device into bootloader mode (i.e. press/hold MODE button and tap RESET)
wait for device's onboard LED to turn green and expose BOOT drive (i.e. XENONBOOT) on host computer
copy .UF2 file to BOOT drive
wait for device to restart

Yes, your procedure is correct
