Hello there,
I’m currently using RAK 4630 5005 Wislock. When I want to connect them to PC through USB, it always showed USB malfunctions unknown devices.
I have tried 3 USB cables, 2 PC, and 3 boards. All showed USB malfunctions.
And when I write s140 hex files into boards, it will show JLINK cannot power on CPU (error -1). I don’t know if it leads to the problem.
The board can operate properly on making ble connections and sending data. But just cannot use USB connections. Thank you.
Hello @zzxxcv, welcome to the forum.
this could be a Windows Driver system (You didn’t mention which OS and which OS version you are using, I am just guessing).
Maybe you can try to run [this driver installation app adafruit_drivers_2.5.0.0.exe and see if it helps.
Hello @beegee !
Thank you for your reply. I use windows. I have just tried the .exe file you sent and restarted. But it still shows unknown USB Devices.
Strange.
Which Windows version are you using?
Can you try the following:
I’m using Win 10 Home 20H2 with Os build 19042.1052
I have tried all the actions you suggested. I tried to press reset twice when I saw your reply to previous post. When I pressed twice, the unknown USB drive page will disappear. Then when I reconnect USB, it still shows unknown USB.
Windows cannot identify it as a normal USB, just an unknown.
That is strange, I am running Windows 10 as well and it installed the drivers automatically.
It uses the build in usbser.sys driver:
I didn’t experience your problem and I have 6 WisBlock Core RAK4631 here. As you have the problem with 3 different WisBlock Base boards, I don’t think it is a HW problem on the Base boards.
Can you send me an image of the WisBlock Base board like this:
Hello @zzxxcv ,
To check your USB drivers please install zadig:
https://zadig.akeo.ie
On zadig menu click on Options-> List All Devices.
This is the correct driver for RAK4630
Hi there,
I am new here, and I am having similar issues. My RAK4630 was working for a little bit, and now the USB connection is not recognized by the PC. It gets detected when i press the reset button twice and it connects as a drive to the PC (FTHR840BOOT). I tested three different cables, and tried on two PCs and one Linux machine. Anyone seen similar issues?
Thanks. N
Do you have any other modules plugged to the RAK5005-O base board?
It could be you need to update the bootloader => Updated bootloader for RAK4631 - #3 by jpmeijers
I had the 1906 enviro sensor, and it is the same after removing it. I will try to update the boot loader. Looks like i have a version from June 2020:
UF2 Bootloader 0.3.2-109-gd6b28e6-dirty lib/nrfx (v2.0.0) lib/tinyusb (0.6.0-272-g4e6aa0d8) lib/uf2 (heads/master)
Model: Adafruit Feather nRF52840 Express
Board-ID: nRF52840-Feather-revD
SoftDevice: S140 version 6.1.1
Date: Jun 16 2020
The upgrade with BLE OTA DFU worked. Thanks!
Good. The bootloader was an old one and had a problem with the USB.
When did you buy the board. All RAK4631 should have the new bootloader already since June this year.
They are still coming out with the original bootloader @beegee, or at least they were four weeks ago
@billr
Thank you for the information. I think I have to step on some toes then.
Sorry for that. They should all be updated already.
@beegee
I bought the Helium dev kit few weeks ago. It will be good if they can ship them with the updated bootloader. Thanks.
