IMX6ULLEVK startup sequence ... how can reproduce it?

[fabio_poiatti]

The IMX6ULLEVK came with an sd card preinstalled ... the startup sequence is listed in the file attached.

The questions is ... I'm having some problem regards new BSP with test tools to upgrade my EVK ... so the question is: knoving the startup sequence is it possible to understand how to reproduce the same sd card image? I mean:

1) git repo

2) distro

3) machine

4) bitbake target

with my command ...

1) repo init -u https://source.codeaurora.org/external/imx/meta-fsl-bsp-release/log/?h=sumo-4.14.78-1.0.0_ga

2) both poky and fslx-x11

3) im6ullevk

4) target core-image-base

I'm able to create a BSP working but without imx-test.... with imx-test the build action failed

So I'm thinking to reproduce the original one

Thanks

Fabio

Hello Fabio Mario Poiatti,

The image on the SD that is included with the i.MX6ULL EVK is one of the images from the Linux BSP. There are two options: downloading the prebuilt images, or building the image trough Yocto.

You may download the prebuilt images for the i.MX6ULL EVK 4.14.78_1.0.0 Linux BSP on the link below (you may need to login to download this file)

https://www.nxp.com/webapp/Download?colCode=L4.14.78_1.0.0_MX6UL7D&appType=license

If you would prefer building the image please download the L4.14.78_1.0.0 BSP documentation bundle containing the i.MX Yocto User’s Guide, which will guide you through this process (link below, you may need to login to download this file)

https://www.nxp.com/webapp/Download?colCode=L4.14.78_1.0.0_LINUX_DOCS

The steps are very similar to what you followed but these instructions will lead you to using the right configuration for this BSP. You would want to build one of the more robust images, either fsl-image-validation-imx or fsl-image-qt5-validation-imx, as these are the images often included on the SDs that come with the boards.

I hope this helps!

Thanks a lot

I've already builded the same repo with core-image-base .... I will try the other you suggested

Thanks

Fabio
