Prebuilt Images

  1. Ubuntu Server 24.04.1 SD card image (2025-03-10)

  2. Ubuntu XFCE 24.04.1 SD card image (2025-03-10)

To create an SD card for booting SP7350 IO Boards, start by downloading the prebuilt image file, such as Ubuntu_Server_24.04.1_for_IOB_20250310.img.7z and unzip it. Once ready, write the image directly to the SD card using the dd command. For example:

dd if=Ubuntu_Server_24.04.1_for_IOB_20250310.img of=/dev/sda bs=1M; sync

Here, the SD card is accessed via a USB SD card reader and mounted at /dev/sda. Depending on your system, unmounting the SD card might be required after the writing process is complete.

umount /dev/sda

To boot from the SD card, set the boot switch to [1 1 0 0] as shown in the diagram below:
