editing .uf2 file
hi, how would i edit the .uf2 bootloader file? i need to switch one of the pins (so that P0.09 does the same thing as P0.02) but from a brief search online (all i can do atm) i couldn’t find a web-based editor. help would be greatly appreciated!

Hello! You can't directly edit a
.uf2 file like a text document. The .uf2 file is the compiled firmware that gets flashed onto the nice!nano.
To change the pin assignments, you'll need to modify the source code for the ZMK firmware and then build a new .uf2 file.
We have template repositories for our Corne and Lily58 keyboards that you can use as a starting point. You can find them on the firmware page of the build guides:
* Corne Wireless Firmware: https://docs.typeractive.xyz/build-guides/corne-wireless/firmware
* Lily58 Wireless Firmware: https://docs.typeractive.xyz/build-guides/lily58-wireless/firmware
These guides explain how to use the template to set up your own ZMK config repository. Once you have your repository, you can edit the .dtsi files (which define the pin assignments) and the .keymap file (which defines your keymap layers).
After making your changes, GitHub Actions will automatically build a new .uf2 file for you. You can download this file from the "Actions" tab in your repository and then flash it to your nice!nano.

If you're not familiar, ZMK is a wireless-focused firmware, and it powers our Corne Wireless.

wait but what if all i want to do is modify a single pin
You're welcome!
Even if you only want to modify a single pin, you still need to go through the process of setting up your own ZMK config repository and building the firmware. The pin assignments are defined in the source code, not something you can change directly in the
.uf2 file.
The build guides I linked in the previous message will walk you through setting up the repository and making changes. It might seem like a lot for just one pin, but it's the standard way to customize ZMK firmware.
Let me know if you have any more questions as you go through the process!
