[Update] GSLX680 Touch driver working!

[Manoj Gudi]

The last touch driver for Aakash is now working..

The driver and firmware provided here workout of the box:
https://gitorious.org/gslx680-for-sunxi/gslx680-for-sunxi.git

However I'd to play around with script.fex file to get the gslx680_ts.ko insert correctly in kernel. Here's the diff:

Why you want it in patch ?

These script.bin's are different for different machines, sometimes even the values in script.bin are wrong and misleading.

Hi, I suggest convert it into a patch so that it can be applied easily:

diff -u oldScript.fex newScript.fex > Modification.patch

Hello,

In wich path should the firmware file be located, to be correctly loaded by the module? Thanks!

[Manoj Gudi]

I think its /lib/firmware

[Rodolfo Bonnin]

Yes, I've read it's the normal location, and the firmware it's sitting there, but the module indicates that it wasn't found. BTW, I'm using a F20 root image. Thanks for your help anyway!

Hello Manoj, would you mind sharing the sd image or root filesystem wich you used to test the driver? Thanks!

I would definitely  share the sdcard image but there are two issues

1. I dont have it now :)

2. Its an image for Allwinner A13. Pretty sure wont work for A20

I am putting this email back into linux_on_aakash google group. Pretty sure Srikant has it, he will help you out soon..
