Hello all,

I am trying the fido branch linux-congatec kernel for MACHINE=cgtqmx6.

More specifically, this DTB and kernel

uImage--3.10.53-r0-cgtqmx6-20150519142407.bin
uImage--3.10.53-r0-imx6q-qmx6-20150519142407.dtb

for the P/N 0161103 (Quad-Core)

Question on the side: I noticed the Congatec pre-flashed setup does not seem to load a FDT DTB from eMMC? Shouldn't these platforms always load a FDT DTB?

I am sure the error is on my side, what did I miss?

Thanks, Leon.

I have recently built and booted an image build with fido on Qmx6 with success. One difference is that I did not netboot but used an SD card attached to the Q7 module.

Your question regarding load of DTB from eMMC, if I remember correct the default script for u-boot-congatec (version 2013.04) will search for kernel and device-tree in mmc device 0,1 and 2 which are 'SD card on module', 'SD card on carrier board' and eMMC. It will use the first found. Could you check the version of your u-boot on the target? Probably you have 2009.x or something that doesn't have support for DTB. In that case you must upgrade your u-boot to 2013.xx in order to boot kernel with device-tree.
