bootimg — Prepare a bootable image for the SiMa DevKit.

Full Help:

Usage:  [OPTIONS]

  Prepare a bootable image for the SiMa DevKit.

  This command downloads the specified firmware version and prepares a
  removable boot medium (SD card or USB) or configures a TFTP-based network
  boot environment. It supports both MLSoC- and Modalix-based DevKits, as well
  as Yocto and eLxr firmware types.

  Operations Performed:

    • Download the correct firmware bundle for the selected version

    • Build a bootable disk image (SD/USB) OR configure TFTP netboot

    • (Optional) Boot the DevKit over the network and flash internal eMMC
    storage (use `f` command)

    • Support for internal/testing rootfs overrides (`--rootfs`)

  Typical Use Cases:

      • Flashing a new firmware version to an SD card

      • Setting up a fast development loop using TFTP netboot

      • Preparing an eLxr-based bring-up image for Modalix DevKits

      • Automating eMMC flashing over the network

  Examples:

      # Write an SD card image for an MLSoC DevKit

      sima-cli bootimg -v 1.6.0 --boardtype mlsoc

      # Set up netboot for a Modalix DevKit

      sima-cli bootimg -v 1.6.0 --boardtype modalix --netboot

      # Prepare an eLxr netboot image for Modalix

      sima-cli bootimg -v 2.0.0 --boardtype modalix --fwtype elxr --netboot

Options:
  -v, --version TEXT              Firmware version to download and write
                                  (e.g., 1.6.0)  [required]
  -b, --boardtype [modalix|mlsoc]
                                  Target board type.  [default: mlsoc]
  -t, --fwtype [yocto|elxr]       Target firmware type.  [default: yocto]
  -n, --netboot                   Prepare image for network boot and launch
                                  TFTP server.
  -r, --rootfs TEXT               Custom root fs folders (internal use only)
  -a, --autoflash                 Net boot the DevKit and automatically flash
                                  the internal storage - TBD
