Using Yocto with IMX6ULL 14x14 EVK

[mitchgaines0]

I'm trying to build a yocto image for my IMX6ULL 14x14 EVK board by following this set of instructions:
https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf 

However, when building an image, only u-boot seems to start. U-boot then never seems to get to an autoboot step or allow access to the console. So, the kernel never starts. 

Here is my build configuration:

I have attempted to build core-image-minimal, imx-image-core, and imx-image-multimedia. All of these result in the same problem. Here is the console output from u-boot:

After that, it seems to just hang with no access to the uboot console

When the system boots from the emmc (with what was shipped on the board), a kernel seems to start.

Any indication on what I need to do here?

Hi @mitchgaines0 ,

Sorry for the late response. Please help me with the following questions to pinpoint the root of your problem:

1. What BSP version are you trying to build?

2.What process are you following to flash your created image? 

3. To what device are you flashing to? 

4. From which OS are you flashing from?

Thank you.

Best regards,
Hector.

Hi,

I build yocto image follow the URL

https://github.com/nxp-imx/meta-matter#how-to-build-the-yocto-image-with-integrated-openthread-borde...

It boots success. Maybe you can check the differences with yocto user guide, just for your reference.
