I am in Belgium and we deal with Gleichmann & Co. Electronics in Germany 
to have their devkit (SMT-C-T10). I have signed a NDA with them to have 
MXT224 protocol guide but they never send me Protocol Guide.
I will try another distributor.

You are right, I already try this and test it again but this does not 
change anything.

So what can I do ? Maybe a problem with the embedded firmware that need 
an update (atmel_mxt_ts 0-004b: Family ID: 129 Variant ID: 1 
Major.Minor.Build: 2.0.AB)

When I do cat /proc/interrupts and I short-circuit /CHG to ground, 
number increases so low-level handling of interrupt is working.

Thanks,
