[bingyuderizi]

the TouchScreen problem has solved, the i2c is not configured right,.

but I still don't know the reason of the exception

[tarterkit_ru]

Hello, please tell me where You get the driver?

I find some variants, but i can't make it with 3.0.35 kernel ...

hadess/gt9xx · GitHub

lolet/gt911_ts · GitHub

[jansirani]

Hai  Pavel,

have you got drivers for GT911 Touch IC for 3.0.35 kernel (Kitkat 4.4.2)?

if you got please share the  drivers .

[jimmychan]

You need to get the driver from goodix.

[jansirani]

hi jimmychan

we are unable to get the drivers from the Goodix thats why we posted in the community.

[WeiWeiBo]

Hi Guo bing

hi... I meet the same question with you... I am Victor

what chip do you use... maybe we use the same chip(GT911)

i also meet the GTP i2c test failed always and then show I2C read error like below

so, i saw you change the I2C configured... could you confer with me what setting you did then become workable  : )

really thx...

Hello

Have You try this patch ?

Re: [PATCH] Input: driver for the Goodix touchpanel -- Linux Input

[bingyuderizi]

I use GT928.  my problem is the IO of i2c which used for touchscreen is changed, but one place I forget to edit,

you can look the IO of i2c which used for touchscreen is right or not, and where the i2c is used is right or not.
