Testing support for newer A320 with ILI9331 LCD controller

I finished disassemblying the .DL hardware initialization code of the newer A320 with ILI9331 LCD controller and modified the code in the kernel framebuffer driver. Since I don't have one of the newer A320 (soon to be fixed, thanks again for your donations) there's no way I can test it, so I need help here. Download the zImage (mediafire, I don't want to upload untested stuff to google code), try it and let me know if the framebuffer works.

If it works, I'll do some minor modifications in the kernel code to allow selecction of LCD initialization sequence and commit it to the subversion repository on google code. I'll be releasing two kernel images until I get one of the newer A320 units so I can work on autodetecting the LCD type.

UPDATE 1 (WRONG): at least one user has reported that the new driver doesn't work. It might be a silly detail but I'm blind and there's absolutely no way I can go any further until I get one of the newer A320. There's enough money in the donation pool (thanks again!) so I'll be ordering it in short (I'm trying to contact CraigX to see if he can make sure of shipping a newer model if I purchase it from him). Please be patient.

UPDATE 2: looks like that was a false alarm. It works. Read this entry.

  1. Hello, Booboo! Thank you for your work.

    I've just got my Dingoo with ILI9331, so I've tried a new zImage for it.
    Under Ubuntu_x64 usbtool successfully loads hwinit but loading of zImage fails with "bulk write error", so I've tried USB_Boot on Windows.
    Unfortunately, after executing of "go 0x80600000 0" it just stays with white screen (nothing else displays on Dingoo's LCD) and usb device disappears.
    There is a log below:

    D:\dingoo\usbboot1.4b-tools>USB_Boot.exe

  2. Hello,

    What is your Linux distribution?
    I still get a error message while loading zImage to device on Ubuntu_8.04_x64 and Ubuntu_8.10_x86.
    And YES: I have files named usbtool, hwinit.bin, zImage in the same directory; I'm root; I'm loading hwinit.bin first (successfully); I've also tried latest version of usbtool compiled from sources.

    There is a thread about this problem [1], but it seems that no solution were found yet.

  5. I use Archlinux 32bit, I used usbtool precompiled of google code, zImage off this post and hwinit off google code. The commands I used are the ones in my post.

  7. I changed system to Ubuntu 9.04 and now kernel loads, boots and works ok. Thanks to all!
