Great progress on #revxlp 10u now that batteries arrives. This time, even with pogo pins…

Hardware assembly almost done. Just got some software issues now - like always I try to get #miryoku on and did build the uf2 file already (the same way I did for the 12u version… hmm), copied over. Now a few keys seem to work but emitting very unexpected (not my miryoku colemak mod dh) keys… Do we need a special miryoku build?

    I checked connections from XIAO to the board and also took off the bottom plate, alu, just to be sure there is no shortcut. When plugging into usb-c and turning on, the green led charge indicator is on, seems to charge. I was previously able to connect via ble, too.

    All right, here is my build run, it is a success and should build a basic miryoku for revxlp - details here https://github.com/hansamann/miryoku_zmk/actions/runs/6761313214

    When I double press reset to have the USB storage of the XIAO appear, it will bring up an error "can’t complete operation because some data in …uf2 can’t be read or written. But I think it copies the 359KB of uf2 over correctly. Then Finder of course shows an error as the device resets into the keyboard mode… all expected, right?

    Unfortunately it still behaves weirdly. The outer three columns don’t do anything. the 4th column top is a ‘w’ then below r and then x… leaves me clueless. I used JLCPCB with the assembly service. On the back of the pcba, I can see some D’s are not places, for example DU D_U2 / D_U4 / D_U3 / D_U9 / D_U8 - but I assume that is all OK. I added the not swap sockets ONLY on the back as the assembly should do the rest on that side of the PCB.

    If you could point me to a ready made build for the XIAO-nRF52840 with a default keymap I am happy to try that out.
