I am currently developing a program for Xiao BLE nRF52 using PlatformIO.
I would like to send a dozen of boards to friends and am looking for a way to flash new boards without PlatformIO (so I can flash many boards in a row, and to let users re-flash without installing anything). I tried the following:
convert my bin program to UF2 with the UF2conv script
double tap RST on the Xiao
dropped the created UF2 file on the flash drive from my PC
this did not work (program was not launched on power-on) and bricked the device (no longer able to upload code from Arduino or PlatformIO)
I realize this might not be a Seeed Xiao specific issue but don’t know where to look.
Thanks in advance!
Thanks for the pointers I haven’t tried nRF connect yet.
I was thinking that for end-users, updating a UF2 would be the easiest. Actually any solution where I can provide a zip file and an script / batch file where they don’t have to install anything, that would be ideal.
Hi there, sure just know it’s adafruit so they have there softdevice and bootloader. also
nrf connect for desktop (free) the programmer can show visually the physical layout of the flash too.
They have a utility forked from it as well.
LOL, after you brick and revive your first one it’s all down hill from there.
