Zero-install embedded training with Zephyr using Kasm and Docker

Golioth enables zero-install embedded training for Zephyr using Kasm and Docker to normalize development environments.

  • The MagTag default bootloader loads UF2 files when the device appears as a mass storage drive after a button sequence.
  • Debugging with Segger Ozone requires downloading the zephyr.elf file instead of the zephyr.bin file from the container.

Where it's used

Hugging Face does not say who downloads a model or with what. These are the proxies: API providers listing it, quantized builds, fine-tunes/adapters/merges, and Spaces that load it.

Served by 1 API provider; 37 quantized builds for local use; a big base for builders (658 fine-tunes, adapters and merges).

The story so far

Weights, every dated article, and repo commits on one rail.

Most coverage came in the first two weeks

Teal is the weights (2023-10-26), amber triangles are 5 dated articles (each links to it), grey ticks are repo commits.

Golioth enables zero-install embedded training for Zephyr using Kasm and Docker to normalize development environments. The solution runs on a pre-configured Ubuntu Focal image where users can compile binaries and flash devices like the Adafruit MagTag via UF2 files. While Kasm offers a free trial for up to 5 seats, the setup automates tool installation to bypass local OS variations and shared bandwidth limits.written, reviewed, cited
  • The MagTag default bootloader loads UF2 files when the device appears as a mass storage drive after a button sequence.
  • Debugging with Segger Ozone requires downloading the zephyr.elf file instead of the zephyr.bin file from the container.
  • Kasm Technologies switches to a per seat licensing model once users exceed the initial 5 trial seats.
