Hi,
Did you get a chance to check if your touch driver reports
BTN_TOUCH with a valid value for touch-down and BTN_TOUCH with 0 as
value for touch-up events?
Regarding the issue with tslib execution, the
--enable-static option passed to the configure command-line may not
link the libc statically. Hence you might want interfere with the
final stage of the linking and ensure "-static" option is passed to
the linker. Basically you need a pure static linking (all libraries
including libc must be linked statically).
Hope this resolves the issue,
Warm Regards,
Anil
