Re: [Ltib] Xfbdev

Hi paolo,

I don't know your board, but I think that this driver is correct. You can load this driver without errors?
I think that the touchscreen be in event0 is not a problem. Did you tried to execute evtest to check if your touchscreen is returning some data?
You can execute:
evtest /dev/input/event1

If the touch is working, when you press the screen, this command must to return some data to you.

Hi Rogerio,
thanks for your suggestion, I try it but without good results.
I'm using an lpc32xx TS, then I have used the module lpc32xx_ts, instead
mxc_ts. Is this correct? Is it normal that there is
the /dev/input /event1 but NOT /dev/input/event0 ?

Best regards,
Paolo
