Subject: Input: atmel_mxt_ts - don't always download device config?
Date: Mon, 12 Jan 2015 10:50:11 +0100	[thread overview]
Message-ID: <54B398D3.7010803@de.bosch.com> (raw)

Hi Nick,

being new to the atmel_mxt_ts and starting to work with it, we wonder if 
it's really necessary to download the device config [1] at each driver 
start up?

I've been told that technically each device config download does mean 
the configuration data is flashed to the device. I.e. it's stored 
persistently, even at power loss.

This would mean that it would be sufficient to check for the device 
config already existing/flashed to the device. And only doing the 
download in case this isn't done already.

Is this understanding correct? What do you think?

Many thanks and best regards

Dirk
