Title: A20 with DEBIAN and TOUCH PANNEL DON'T WORK
Post by: junetec on July 30, 2013, 01:40:06 AM
Hello,

I just write the debian image of the A20 on a SD and try it.
I had change the script file for a 1024x600 script to work with the 10"LCD+ Touch Screen.

It looks like almost everything works fine but the touch pannel don't work.

I need it.

It's something that can be change/install to enable the Touch Scrren ?

regards,

Enric

Was that the second release?  It was missing in the first release.
My 10" worked fine (after running ts_calibrate).  No changes needed.
Maybe the touchscreen connector isn't seated correctly?
Do you see something like this in the boot output:

Lurch: Same problem here. Where did you find ts_calibrate? It was not in my path. Saw it in libts-bin, so I apt-got that but when running ts_calibrate, it says "ts_open: No such file or directory". Thank you for your help.

My debian came on an usd-card from olimex. I have the A20-Olinuxino-micro with the A13-LCD10TS. The LCD works fine, just stuck on the touch screen.

And I don't see the "sunxi-ts ..." messages in dmesg, so I may have an old release without that module.
