SATA HDD on Wandboard Quad with Fedora20

I'm install FC20 into WB-Quad by following URL.

https://fedoraproject.org/wiki/Architectures/ARM/F20/Installation#For_the_Wandboard_.28Freescale_i.MX6.29

But it's cannot see any SATA devices on board. I've found solution on following URL.

http://www.swissdutch.ch/sata.php

It's require imx6q-wandboard.dtb but URL on site are loss. But I've found new on URL.

http://less.cogeco.net/fedora/linux/development/rawhide/armhfp/os/images/pxeboot/dtb/

And I choose imx6q-wandboard-revb1.dtb (My board is rev B1). Put it into __boot/dtb/ on sd-card. Then I'm modify __boot/extlinux/extlinux.conf by changed

"ftd /dtb/imx6q-wandboard.dtb"

to

"fdt /dtb/imx6q-wandboard-revb1.dtb".

Then create /etc/modules-load.d/imx.conf. This is inside it.

# Load ahci imx at boot
ahci_platform
ahci_imx

When I'm create directory /hdd finished i'm put this line to __/etc/fstab

/dev/sda1   /hdd ext4 defaults 0 0

And Then reboot.

iMX6-Quad wandboard cannot load fedora linux kernel problem solve.

I've install Fedora20 into Wandboard Quad by following URL.

https://fedoraproject.org/wiki/Architectures/ARM/F20/Installation#For_the_Wandboard_.28Freescale_i.MX6.29

But it found problem about cannot load linux. This is my error message.

Wrong Image format for sysboot command
ERROR: can't get kernel image!

I think it cannot find image on SD-Card. But I'm found this page.

https://fedoraproject.org/wiki/User:Mrunge/Wandboard_quad

And I'm recheck __/etc/fstab. This result

[root@localhost etc]# cat fstab
UUID=67fd65e0-63d0-492d-bac9-f1a7702e30ca  / ext4    defaults,noatime 0 0

UUID=a6c693c6-99c1-4e79-b522-7cae47d96d38  swap swap    defaults,noatime 0 0

It's show root is mounted on UUID=67fd65e0-63d0-492d-bac9-f1a7702e30ca.

But when I'm cat __boot/extlinux/extlinux.conf it's show result.

        fdt /dtb/imx6q-wandboard.dtb
        initrd /initramfs-3.11.10-301.fc20.armv7hl.img

It's show root path is UUID=7ee85ed8-de4a-4779-8658-2daed0d35e97. Oh my god UUID is not correct. When i'm change UUID in __boot/extlinux/extlinux.conf to 67fd65e0-63d0-492d-bac9-f1a7702e30ca now it's boot correctly.

EMC2 Video card Problem solve.

if you have problem about glx and etc on start up emc2 software on ubuntu 10LTS. It's mean you have video card problem i think. My System have PIII 1.13GHz and Voodoo5 5500 AGP card. Now I can solve this problem by use the following solution.


press CTRL + ALT + F1
login and run following command

sudo service gdm stop




sudo apt-get build-dep xserver-xorg-video-tdfx
sudo apt-get source xserver-xorg-video-tdfx
sudo apt-get install libglide3
sudo ldconfig

cd ~/xserver-xorg-video-tdfx-1.4.3/
./configure
make
make install
cd /usr/local/lib/xorg/modules/drivers/
sudo cp *.* /usr/lib/xorg/modules/drivers/

sudo Xorg -configure
sudo mv ~/xorg.conf.new /etc/X11/xorg.conf

Add the following red line to /etc/X11/xorg.conf

Section "Device
            Identifier   "Configured Video Device"
            Driver "vesa" 

Section "Module"
            Load "glx"
            Load "dri" 
            Load "GLcore"
            Load "v4l"
