It shows me a layout named "Vim for Trebisky".
A button at the bottom says "Save to my keyboard". Below that it says "Teensy chip detected". I try the "Save to my keyboard". It tells me to use a paperclip to press the reset button, then connect -- but it doesn't seem to work.
A link says download firmware. This yields ergodox_ez_shine_vim-for-trebisky_4Jbyn_pMR5d.hex in /home/tom/Downloads and is exactly the same as a file with the same name from October of 2021.
At top right is an orange field that says "firmware v20.0" and when I hover over it, it says "this layout is based on outdated firmware, recompile to update.
To recompile, I need to go to the "My Layouts" page, select my keyboard, click Modify and make changes, then click the Compile button.
I do a trivial change, labeling an undefined button as "Test". After this the button at the bottom center now says "Compile this layout". I click it -- now I see "firmware v25.0" at the upper right. I use the "download firmware" button to save the hex file.
zsa_ergodox_ez_m32u4_shine_4Jbyn_9DBAGL_vim-for-trebisky.hexThey have made a couple of nice changes. The "zsa" prefix puts this at the end of my "ls" listings. And putting the checksum like code in the middle is nice too.
I use "Wally" to flash this. It takes only 2 seconds or so. The lights under the keyboard come on. Now I launch "keymapp" from the command line and it works (it did not work prior to me flashing the new firmware).
