Linux on Q7

[cchandel]

Hi,
To get Linux (partly) running on the Q7 with the root file system on a SD Card, you can do the following. Be aware that this method is mostly of little use since a number of things are not working as the kernel in use doesn't suppport this box completely.

Here are the steps :-

a) Download DNSounds Minix kernel stuff - https://www.dropbox.com/s/ozcmjgh08w...-Linux3188.rar

b) Download DNSounds latest 30101 kernel - https://www.dropbox.com/s/8nmtnog2i7...SD%201080p.img

c) Download RK3188Loader V2.10 or above

d) Download you favourite armhf rfs (I used http://archlinuxarm.org/os/ArchLinux...-latest.tar.gz). Create a SD Card with ext4 fs using mkfs.ext4 -F -L linuxroot /dev/sdX, and extract the files from the rfs tarball to this partition

e) unrar the file downloaded in step a)

f) Use ROM_Flash_Tool_137 (part of file in setp a) to erase NAND(IDB)

g) Then, use the ROM_Flash_Tool_137 from windows to flash the Q7 with the following selections :-

i) Loader - RK3188 Loader v2.10
ii) parameter - select parameter file from rar file
iii) kernel - downloaded in step b)
iv) boot - select boot.img from rar file

g) The device should reboot and start in linux

Not Working :-

a) NAND Access
b) Wifi
c) Ethernet
d) BT
f) Sound
e) .....

Partly Working :-
a) Teh display seems to be scaled smaller than a 1080 screen - looks ugly

Working :-
a) X windows using fbturbo drivers

Seems usable performance wise - but can do with a better kernel.

I've tried making a better kernel - but all my attempts with Omegamoon, thesawolf, Galland repos don't boot. I've been using the .config from DNSound's kernel - but no joy.

Hope some Kernel Dev can create a better one that supports more hardware. I would welcome pointers to :-
a) Kernel source git
b) Toolchain (I'm using linaro)
c) Changes / modifications to get the hardware working

Once a kernel is available that enables access to the NAND - the rfs can also be moved to the NAND.

Please help if you can.

Thanks.

Progress - working kernel

Hi,
I've got a 3.0.101 kernel working on the Q7. Files are here kernel and wlan.ko module for RTL8188EU.

Most things work - those that don't are :-

a) NAND access - I think the problem is with the new loader - but I've not been able to downgrade to 1.24 from 2.1
b) ethernet
c) Bluetooth - comes up - but not tested

Can someone throw a light on why I get these errors ?
