Re: mx6sx kobs-ng

peterbärtsch — Wed, 02 Dec 2015 13:45:42 GMT

I add only imx-kobs in my IMAGE_INSTALL_append config. Is that wrong? Need imx-kobs other packages to run correctly?

Kernel is linux-fslc-mx6_3.14-1.0. I have to fix this week :smileyshocked:

Can someone help me?

Hi,

It is great news you found the problem. I wonder if you can share the solution?

That would be very appreciated.

Peter,

I have the same problem.

Can you share what was the h/w issue, bad NAND chip, wrong pin muxing?

Hello,

You should use version 5.4 from 'meta-fsl-bsp-release' instead of version 5.1 from 'meta-fsl-arm' Just in case is the issue.
