3 weeks ago I have also attempted to flash the device using nRF Connect.
If plugging it in in non-DFU mode it never finishes mapping memory for the device:
If plugging it in with DFU enabled, it cannot flash it, as it errors with No operation possible:

3 weeks ago I have attempted to flash it with nrfutil:
$ sudo nrfutil dfu usb-serial -pkg ot-cli-ftd-dfu.zip -p /dev/ttyACM0
[------------------------------------] 0%2024-11-02 04:29:22,398 No Libusb1 context found, but is required to use DFU trigger. This likely happens because the libusb1-0 binaries are missing from your system, or Python is unable to locate them.

3 weeks ago Okay, figured it out. It has to be converted to a hex file first, then a uf2. Can just drag the file as is into the uf2boot drive, doesn't need renaming.
I have a
Makerdiary nRF52840 MDK USB Dongle.Info.txt:
I'm trying to set it up for Thread by installing: https://github.com/openthread/ot-nrf528xx/blob/main/src/nrf52840/README.md on it.
Steps (in Docker):
On Windows 11:
CURRENT.UF2,INDEX.HTMandINFO_UF2.TXTDrag and drop the UF2 file onto the UF2BOOT volume.. Do I need to rename it toCURRENT.UF2, or just leave it asot-cli-ftd.uf2? Either way I've attempted both. I drag the file into the folder for the nRF52840 device and I see the light is rapidly flashing red. It takes about 1 minute to finish copying over, with the light flashing red the entire time.CURRENT.UF2and alsoot-cli-ftd.uf2. If I unplug the device and plug it back in with bootloader mode enabled, the originalCURRENT.UF2file is there. I have tried compiling the binaries with -DOT_BOOTLOADER=USB set and not set.
