Hello: Just getting started with the i.MX 8M Quad Eval kit. I'm interested in running Linux from the sdcard. To start with I have downloaded a pre-built example from the knowledge base L4.14.98_2.0.0_ga_images_MX8MQEVK. From here I reference the i.MX Linux guide, chapter 4.3.2 "Copying the Full SD Card Image". Issuing the command sudo dd if=fsl-image-validation-imx-imx8mqevk.sdcard of=/dev/sdb bs-1M && sync this yields 2 partitions on the SD Card a Boot imx8mq and a 2.0 GB Volume.
Install the sdcard and change SW801 to 1100 and I get no activity. is the .sdcard file intended to be all that you need to boot from the sdcard, or is there another step?
Thanks for the help, in the end I discovered a utility (balenaEtcher - Home ) to be a good & faster alternative.
Hi, Richard Earle
Please use below commands to flash the images, you will be able to get the board boot,

Hello, in referencing your suggested link i.MX6qp Sabre AI cannot boot the validation sdcard image, it states the dd command can't be used and you must use the universal update utility.
1. if the dd command can be used, can you explain further, by providing an example?
I have attempted to follow the suggested link with uuu and this results in failure, with the associated debug output from the evk.
I assumed from the suggested link example you provide the boot image followed by the .sdcard image, and from the L4.14.98_2.0.0_ga_images_MX8MQEVK example these are the correct files.
Hi Richard,
The dd command is more intended for flashing a SD card after generating the .sdcard file when compiling Linux from source code.
On the recent versions of the Demo images, it will be required to additionally flash the specific U-Boot, in order to ensure proper boot for a specific platform.
You could refer to the following Community thread:
i.MX6qp Sabre AI cannot boot the validation sdcard image
As a detail, if you already have all the SD card flashed, you would only require downloading the proper U-Boot, and this could be done with UUU or with dd command.
Hope this will be useful for you.
Best regards!
