[LeshaK]

Add support LCD - 320x240, 640x480, 800x480

Now working:
- ethernet cs89x0. Boot kernel, rootfs (nfs).
- USB (usb hid, mass storage, usb to serial etc.)
- MMC/SD/SDHC. I've tested SDHC KINGSTON 32GB (SD4).
- LCD. Support: 320x240, 640x480, 800x480. I've tested only 640x480 (I have only 5.6" LCD 640x480)
- RTC

Current patch for 2.6.28.8 (config include)

Nice job done!

I am thinking to have other customers of QQ2440 to make some test and comments on that. Do you agree?

[LeshaK]

yes ,
May be check LCD resolution 320x240 etc...
I don't have such lcd, only 640x480...

I saw your video on Youtube. It is really cool!
BTW, What kind of graphics system used on board?

[LeshaK]

On video - I use this Opie (qt)
download Angstrom rootfs with Opie Desktop Environment rootfs. Extract/copy to SDHC and use as root filesystem.
Work (I tested):
- Video
- Ethernet
- Touchscreen
- SD
- USB (on video I connect usb flash and open jpg file)
- Bluetooth (bad video quality and I didn't include on youtube), but used usb bluetooth, and found some bluetooth devices
Now I use u-boot in NAND
u-boot load kernel from NAND in RAM, and rootfs on SDHC 32GB (I tested rootfs on USB flash - ok, rootfs on nfs - ok too.

I didn't test audio and power managment yet.

Today I installed Debian (lenny) on qq2440, it was simple and fast
Later, I will write how to install Debian to QQ2440 or mini2440 or any arm devboard (on SD card).
