• ​noble-catalina.img.gz Ubuntu 24.04 (Noble) based root filesystem image with the default ​Gateworks kernel
  • To update the firmware on the eMMC see catalina/firmware
  • To update the firmware on a microSD card see linux/blockdev
• ​linux-catalina.tar.xz - Compressed TAR archive of pre-built Linux kernel

Login Information (default)

• Ubuntu aarch64 core (created via BSP)

  • Filesystem tools: e2fstools parted
• first-boot script to grow root filesystem partition and filesystem (useful when putting disk images on removable storage devices)
• use ifupdown tools instead of netplan (we find them easier to understand and configure)

To install the kernel and root filesystem on a removable block storage device see below.

Notes:

• By default root ssh access is disabled for security. See This link for info on enabling it

BSP

To build a complete Ubuntu image, including all the boot firmware, start with the Catalina BSP page as the easiest option.

Root Filesystem

Building a Bootable Disk Image

You will want to build your own Ubuntu disk image if you want control over any of the following:

• Contents of root filesystem (packages and configuration) (see [#debootstrap debootsrap below)
• Configuration of the Linux kernel (see catalina/bsp/kernel)

See catalina/firmware/disk-images for detailed instructions.
