[fedora-arm] F23 on Wandboard Quad -- kernel doesn't start?

[Derek Atkins]

Hi,

I'm trying to run F23 on a Wandboard Quad, but it's not booting. It
hangs after the "Starting kernel" output.

I followed the instructions at
https://fedoraproject.org/wiki/Architectures/ARM/F23/Installation#For_the_Wandboard_.28Freescale_i.MX6.29
starting from Fedora-Minimal-armhfp-23-10-sda.raw.xz I installed the
image, then copied in the SPL and u-boot.img. But when I try to boot my
wandboard I get:

U-Boot SPL 2015.07 (Sep 12 2015 - 11:53:19)

Starting kernel ...

And then the system just sits and hangs.. Is this a known problem?
I tried with two different SD cards and both fail.

I could certainly revert back to F22, but why start 6-months behind?

If you are on serial you might need to add console=ttymxc0,115200 to the
kernel bootlinux in extlinux.conf
I never tried to boot using hdmi output, so I usually need to add console
there.

Recent arm-image-installer has a --addconsole option to do that for you.

I guess it serves me right for not updating that script. I'm still
using 0.06 (plus some changes to support wandboard on f23). But it
still would've been nice to have at least a one-liner on the wiki :)

The wiki is just that -- a wiki. if you think something needs to be added
to it, do it!

That implies having a FAS account, which I don't. Faster for me to
suggest a change than get one set up.

Aha. Thank you. This is exactly what I needed.

I didn't see this anywhere on the F23 wiki page, and I didn't need it
for F22, 21, or 20, so this IS a change in default behavior. Perhaps
this suggestion should be added somewhere on the wiki:
