I bricked 2 of my XIAO nrf52840 non-sense already (bootloader not accessible) and want to unbrick them using my JLink.
I’ve read this thread here: Looking for Xiao BLE "official Bootloader/SoftDevice code/source - #3 by leroyle but am not quite sure if this is still the way to go - why can’t Seeed simply give us the original bootloader-file ready to flash?
Or is there another way to unbrick it via JLink?
Generally you would build a copy of blinky and use that during recovery as your .hex file, but I do agree stock flash files would be nicer.
wait, would that include the bootloader if I build blinky? I thought this would always only be the application?
Hi there,
So I think this is crossed up, They do provide the HEX…
the wiki, HAS a direct link here.
I use it often, Write it with the SWD connected and after write a blinky of your choice.
