Dear all

I made ​​sure that 10 inches lcd (HSD100PXN1) that work well against the Touch from i.mx6q cpu board.

So when you connect the 7 inches LVDS LMS700JF01-001 not touch the image is well Scary . The touch IC, MAX11801.

When the touch panel interrupt and I2C operation are good . However, this operation is not on the screen. The MAX11801 logo message appears that connection . Of course, X +, X-, Y +, Y- been brought up signal is properly connected.

Please comment why the touch no operation .

Hi kim

for touch test one can try ts_test (tslib package in ltib)

also it makes sense on other examples:

imx6 sabre-sdb and LCD touchscreen MAX11801

Touchscreen support on IMX6 Evaluation Kit

Configuring i.MX6 boards for different screens
