Standalone keyboard not registering keystrokes

MNT Reform
1

Hello there,

I received my standalone keyboard last week. I received it without switches, I installed Kailh Choc v1 Purpz in it.
It doesn’t register any keystroke.

I tried:

  • on a Windows PC
  • on a Linux PC
  • with the included USB-C cable
  • with another USB-C cable from another keyboard

But so far, I only see the MNT RE logo on the OLED screen and the lightings below the switches.

I’ve looked so far:

  • in the community forum
  • in the gitlab server
  • in the handbook

but I didn’t find where to start debugging this.

Thank you for any help!

Can you post what appears in sudo dmesg -w when you plug the keyboard in? Kinda sounds like it may be stuck in firmware update mode.

Thank you.

The process hang after that so I stopped (Ctrl-c)

That looks how I would expect. Have you tried flashing the latest firmware yet?

5

Yes, I followed the instructions of Paul from MNT.
Same result , still not working…

Could it be hardware?
I received it without switches and I put switches inside, hotswap. I checked that the pins were straight everytime but maybe I missed something else to do?

@vkoskiv I didn’t realise that I needed to solder the switches :man_facepalming:. I’ll keep you posted. Thanks for taking the time to answer my questions.

That was going to be my next question :smile:

Glad you got it figured out!

I didn’t figured it out, I got help from MNT’s Paul :grin: . I am just a humble beginner in this kind of field…

All soldered
