Trying the last few commits of this repo to build images that support the clearfog variant of your board, but none are bootable. So far, I've tested SD1= 13/14/17/21 and all fail with the same error:

(boot logs from 14_5_2 build, which you seem to mention is tested in other tickets)

could you publish a known working image that demonstrates QSFP support? If the above issue is related to my build env, it would be helpful to have a working starting point...

Still digging in hopes of some functionality with anything other than 8_5_2. I find another user's report of the same issue, so following his hack, I can get one step further, but it doesn't seem clear where this requirement is coming from yet...

editing runme.sh I add a dirty hack to force the missing file to exist & add it to the image:

cp $ROOTDIR/images/tmp/boot/fsl-lx2160a-clearfog-cx.dtb $ROOTDIR/images/tmp/fsl-layerscape-lx2160a.dtb
... add to e2cp line

Cool. That gets one step closer... but...

so, 14_5_2 build still thinks there are 4x sfp ports to bring up (despite SD1 config for a single QSFP)... as well as apparently missing initial device nodes.

Does anyone else have this issue? Thoughts?
