Convert RAK4631 to RAK4631-R (again)

WisBlock

Hi, I need some help converting RAK4631 to -R

Im confused after reading posts and “step 2” in following this tutorial (updating-rak4631-to-rui3) - https://docs.rakwireless.com/Product-Categories/WisBlock/RAK4631-R/DFU/#updating-rak4631-to-rui3

Iv managed to flash the boot loader ok but step 2 says that I should flash rui3_rak4631_latest.zip but it fails what ever I try.

log from latest try

$ adafruit-nrfutil dfu serial --package rui3_rak4631_latest.zip -p /dev/ttyACM0 -b 115200

TypeError: SoftdeviceBootloaderFirmware.__init__() got an unexpected keyword argument 'info_read_only_metadata'

Im running Linux, Ubuntu 22 and I also have the RAKDAP1 to go back to Arduino (and that works fine).

Any help much appreciated!

Welcome to the forum @tomas

After you flashed the RUI3 bootloader, you have to flash the application with the nrfutil.exe, not with the adafruit-nrfutil.exe:

Thanks for the welcome and info @beegee !!

Well I have tried this to (on linux) and will do it again to paste the outcome.

Last run, still a problem…

edit: is there a .hex file for RUI3 fimware?

Yes, there is a hex file.
I never tried it with DAPLink. I am always using JLink.

Downloads ==> RAK4631_latest_final.hex

Thanks!

Flashing seems Ok, but no response on USB port after flashing!?

Try a chip-erase.
If that doesn’t work either, try to flash this
RAK4631-RUI3-V4.1.1-Flash-Dump.hex (2.4 MB)

Solved after erasing !

14:18:28.815 -> AT+VER=RUI_4.1.1_RAK4631
14:18:28.815 -> OK
