Android ICS for 4" screen

[Jason Freeman]

Hi

I am wanting to run ICS on a 4" screen. I would also like to attempt to get touch screen calibration working. If somebody could please give me a rundown of what I need to do to get this working, and assist with some technical support through the process, I am happy do do the legwork and submit the image once done.

Thanks

Any update on this topic?

Thanks!

1. Change kernel for your screen according to this: http://arm.mini-box.com/index.php?title=Kernel_changes_for_custom_hardware#How_to_compile_kernel_for_a_7.22_touchscreen

2. Write ICS image to a sdcard. Image is here:  http://arm.mini-box.com/releases/android-4.0.3-ics-kernel-3.1-2012-02-08.zip

3. Mount the sdcard and replace the uImage from the FAT16 partition with your kernel from step 1

4. If you are using resistive touchscreen connected to picoSAM9 copy: http://arm.mini-box.com/releases/Calibrate.apk to /system/app in the sdcard ext3 partition

You can also have usb keyboard/mouse on ics if you need to troubleshot

Thanks for the fast reply Nicu,

I did everything with respect to your instructions.

The only issue left is the impossibility to find the exact parameters for my display p/n: MI0500LT, Multi-Inno Technologies Co LTD.

The display is 4.3 inch and has resolution 480x272

Seems like all the issues with the touch screen calibration comes from this issue.

The Calibrate.apk does not appear in the apps after boot up the OS so I cannot use it.

If you have any Idea how to solve it, please let me know.

Regards and Thanks once again!

You can just replace the kernel with one from Android Gingerbread after you write the ICS image.

Thanks for the fast replay ,Nicu !

Unfortunately I`m not quite familiar about how to “replace the kernel with one from Android Gingerbread”.

 

It will be great if you can give me some advice here .

 

Thanks again !

Write the ICS image on a microSD. Replug the microSD on the card reader and mount the first partition which is FAT16. Replace the uImage with the one from here: http://arm.mini-box.com/releases/kernel_bootstrap/latest/uImage

Hello Nicu,

I`ve followed your instruction and now I have Android ICS. Thanks !

Now I have the following problem - there is a circle (which act like mouse pointer) and it is very difficult for me to navigate/slide up down etc. Is there any option to disable this circle and to navigate like Android 2.3.4 for example ?

[pico-fan]

i am working on this issue. Will share the fix soon.
