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,
