1. Downloading the Debian image

Download the Debian image by running the following command on your Linux/Windows PC:

1 wget https://solid-run-images.sos-de-fra-1.exo.io/8040/Debian/sr-8040-debian-buster-20190616-cfgt-sdhc.img.xz
  • For more Debian releases, Download a pre-built snapshot image from SolidRun Images

2. Writing the image to the SD card

Use the following commands for writing the image to an SD card:

1 xz -dc sr-8040-debian-buster-20190616-cfgt-sdhc.img.xz | dd of=/dev/sdX bs=4k conv=fdatasync

Note: Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

3. SD card insertion

Please Insert the SD card into your device.

4. Power connection

Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.

5. Serial Connection

Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.
