Imx8qmmek Sdcard Image Support

[abossert]

Problem

I need help getting a bootable sdcard for the imx8qmmek. The software from the release site here contains a .sdcard image. If I write that to an sdcard the system boots. What I want to be able to do is build that image. When I try to build an image with the steps outlined in the fsl-community-bsp-platform repo I do not get the .sdcard image as an output.

A solution would be to get the steps to build the sdcard image.

Things I've Tried

I have tried the .wic file output but it does not boot board. When I inspect the wic file with fdisk it doens't match the .sdcard image in the release. This leads me to believe the wic isn't being created correctly or its not the image I need to create a bootable .sdcard.

.wic image:

.sdcard image:

I'v also tired adding sdcard to IMAGE_FSTYPES in my local.conf. I get the following build error when I attempt this.

Any support is appreciated.

Following up; I was able to build the .sdcard image. What I was doing wrong was using this setup command from the fsl Community BSP.

 source ./setup-environment build

This will no pull in the layer needed to build the .sdcard file. The .sdcard file support comes from meta-fsl-bsp-release, specifically the image_type_fsl.bbclass. In order to get that layer use the setup command in the Linux L4.14.98_2.0.0 Documentation. 

$ DISTRO=<distro name> MACHINE=<machine name> source fsl-setup-release.sh -b <build dir>

Also which url is used to repo init is important too. The manifests here will pull in the meta-fsl-bsp-release layer but the FSL Community manifest will not.

Hey igor,

Thanks for your quick response. Is there a specific command or script, like a bitbake recipe, you can point me to to recreate the .sdcard image or are these manual steps the best way to create a bootable sdcard for the Multisensory Enablement Kit?
