Notes & Tips

Flashing Firmware From Linux

I’ve found that the web serial driver, even when using official Chrome, doesn’t install from the manufacturers website when running Ubuntu 25.10. I believe this is due to newer Kernel and Kernel header source location. I’ve had to use the CLI to flash all 3 devices so far.

Flashing from the CLI is pretty straight forward. Follow the instructions in the following link: https://meshtastic.org/docs/getting-started/flashing-firmware/esp32/cli-script/. I’ve had very good success using USB-C to USB-C cables that came with my Samsung phone. You need to ensure the cable can pass data, not just charge.
