Nano-X issues

Hello,

I'm running uClinux on the NEEK controlling an external touch screen display (Elo Touch) with Nano-X included in the kernel config.

Everything works fine. I set Nano-X configuration to use tslib for touchscreen device.

Set the right parameters on uClinux for TSLIB and performing calibration (ts_calibrate) works well.

Now starting Nano-X, my touch events won't get recognized.

Does the Nano-X windowing environment need extra Elo touch screen drivers to support touch handling?

Can someone provide advices on that problem?

Thank you in advance.

D.

    Of course the MMU enable full Linux system prevernts overriding of Kernel space by userland applications and thus is a lot safer. Moreover only the MMU enabled distribution decently supports threaded applications.

    So if you have enough FPGA resources for the MMU and are not too tight with CPU performance, you maybe should convert.
