Hi folks,
I've got a really strange booting problem on an phycore-imx6
based board (pretty much the same as mira):
* barebox v2017.06.1-phy2 comes up properly, but cant boot
the kernel (v4.13) - just hangs w/o any output (not even
uncompression message)
* putting the kernel manually into the factory-image (sdcard)
w/ old 2015 barebox boots the kernel
* w/ DEBUG_LL + earlyprintk it doesn't even does that, just
hangs like w/ new barebox
Here's the last output I've got: (added few more debug outputs)
> Loading ARM Linux zImage '/mnt/mmc/boot/zImage'
> Loading devicetree from '/mnt/mmc/boot/imx6q-phytec-mira-rdk-emmc.dtb'

My first suspicion was zero'ed DT memory node (which OTOH doesn't
explain why earlyprintk doesn't work), but fixing that didn't help.
Could there be any vital low-level init missing in the new bbx ?
Maybe the entry point correct ?
Any ideas where I could have a deeper look at ?
thx.
