#NRF52840 no CIRCUITPY
pallid rain
no, can't get to the REPL using a DELL 7530 Precision. I have SEED XIAO and RP2040 and Pico all working great for a long time now

odd -- did you try updating the bootloader?
pallid rain
I just saw that bootloader file, I dragged it to the MDK-DONGLE drive, nothing happend, is there another step?
native gale
no - try -- double tapping reset -- does the Boodlader Drive show up?
If so what is in the INFO_UF2.TXT file
My drive mounts as MDK840DONGL
in bootloader mode
Are you still able to get to the bootloader?
pallid rain
yes, just tried double tapping reset, that did nothing
native gale
what is in INFO-UF2.TXT
pallid rain
UF2 Bootloader 0.2.13-42-g82464f9-dirty lib/nrfx (v2.0.0) lib/tinyusb (legacy-1500-g23df777b) s140 6.1.1

so it did not update....
Model: MDK nRF52840 USB Dongle
Board-ID: nRF52840-Dongle-v1
Date: Dec 14 2021
SoftDevice: S140 6.1.1```I was just reading about using nrfutil is that what I need to do? I saw it starts a COM port in bootloader mode, should I be able to connect to that in some way
native gale
I'm not sure -- it's been a long time since I did that on mine. It may be worth updating to the bootloader here https://wiki.makerdiary.com/nrf52840-mdk-usb-dongle/programming/#upgrade-to-uf2-bootloader-from-open-bootloader since it is a bit newer than yours, then try updating to the latest.
I'm not quite sure how to get into the DFU Mode now that the UF2 bootloader is installed.
Mine boots to CircuitPython if I plug it in with the RESET button held then release.
I am not able to get nrfutil to connect to the board. I don't seem to be able to get it into OpenBootloader DFU mode.
pallid rain
I got nrfutil to connect and download, said it was succesful, but I think it
I think its the same firmware as before, it
it
it's behaving the same anyway
native gale
hmmm -- what if you now try to update to the newest bootloader -- just copy the uf2 to the board
pallid rain
I dragged it there, but it doesn't install, it just sits there in the drive, nothing happens
it should run the new uf2 file but it doesn't
native gale
what does info-uf2.txt have in it now
pallid rain
UF2 Bootloader 0.2.13-42-g82464f9-dirty lib/nrfx (v2.0.0) lib/tinyusb (legacy-1500-g23df777b) s140 6.1.1

native gale
that is still your original -- the one I think you tried to install vial nrfuil was 2.13.44
pallid rain
how do I get a newer one to install with nrfutil?
native gale
did you try instalting this one? https://wiki.makerdiary.com/nrf52840-mdk-usb-dongle/progralming/#upgrade-to-uf2-bootloader-from-open-bootloader -- nrfutil dfu usb-serial -pkg uf2_bootloader-0.2.13-44-gb2b4284-nosd_signed.zip -p <your-serial-port-name>
that should have updated from 2.13.42 to 2.13.44 but it does nott appear to have done that.
I don't know what is going on. Hopefully someone else will come online soon who knows more about this....
pallid rain
yeah, nrfutil says it's uploading
nrfutil --verbose dfu serial --package uf2_bootloader-0.2.13-44-gb2b4284-nosd.zip -p COM20 -b 115200 --singlebank

looks convincing -- hopefully info-uf2.txt is updated!

I wish I could be of more help -- I'm stumped
