Hi,
i compiled the current yocto (2.4) for the wandboard. The LCD is working fine, but the touch is not working. I found, that the driver for an ADS7846 is loaded, but it's the wrong driver - I think!?
Bootlog snip:
{CODE]
ads7846 spi0.0: touchscreen, irq 140
input: ADS7846 Touchscreen as /devices/soc0/soc/2000000.aips-bus/2000000.spba-bus/2008000.ecspi/spi_master/spi0/spi0.0/input/input0
[/CODE]
So I searched in the sources from older android images and found there a kernel module for the Adapter Board for that LCD and the info that it's a Prism Touchscreen. But in the current Kernel 4.1.44 the driver is missing.
What is the best way to get the touch running with Yocto 2.4?
I tried also the Yocto 2.0 build from the wandboard FTP. It's the same problem.
The reason to compile a newer yocto is, that I need a newer Qt...
Best regards,
Michael
