Flashing a prebuilt AutoSD image on Texas Instruments (TI) SK-AM69 Jacinto

Follow this procedure to flash the prebuilt AutoSD image onto the SK-AM69 Jacinto board.

Prerequisites

• An AArch64 system with internet access
• An SD card
• A TI SK-AM69 board

Procedure

1. Identify the name of the latest nightly image and store the value in a variable called AUTOSD_IMAGE_NAME.

   export AUTOSD_IMAGE_NAME="$(curl https://autosd.sig.centos.org/AutoSD-9/nightly/TI/ | grep -oE 'auto-osbuild-am69sk-autosd9-qa-regular-aarch64-[0-9]+\.[A-Za-z0-9]+\.raw\.xz' | head -n 1)"
   

2. Download the image.

   wget -O auto-osbuild-am69sk-autosd9-qa-regular.raw.xz http://autosd.sig.centos.org/AutoSD-9/nightly/TI/$AUTOSD_IMAGE_NAME
   

3. Uncompress the compressed .xz image file:

   xz -d auto-osbuild-am69sk-autosd9-qa-regular.raw.xz
   

4. To flash the uncompressed image onto an SD card, replace </dev/sdX> with your block device.

   dd if=auto-osbuild-am69sk-autosd9-qa-regular.raw of=</dev/sdX> status=progress bs=4M
   

5. Set the onboard DIP switches to SD boot mode SW11[1-8] = 1000 0010 SW7[1-8] = 0000 0000.

6. Plug in the SD card, and then start the system.
