Are you also doing a RESET Try putting in a delay before the first read, eg 500ms. It may be that the chip is not ready, it takes some time to settle after power on. > I saw a lot of patches from you on this driver, which are not there in > mainline yet. Are you using any local patches also? Daniel does have some other stuff that hasn't been merged yet. You will also find some official atmel kernel updates, and some useful utilities here: https://github.com/atmel-maxtouch It would be desirable to push this work upstream, I don't know of any manufacturer which is shipping the unchanged mainline kernel, most of them have diverged considerably. > Is it possible for you to share your touchscreen configuration > parameters as there might be some parameters which I might be > configuring wrong? > > Any pointer on above point will be really helpful. I don't know what platform you are working on, but if you contact your Atmel sales representatives they can provide you with the protocol guide documentation on the tuning parameters. It generally requires an NDA. cheers -- Nick Dyer Software Engineer, ITDev Ltd Hardware and Software Development Consultancy Website: http://www.itdev.co.uk -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
