Summary: nano-x with tslib caused high CPU usage

Details:

 

Test nano-x with tslib support on BF548-EZKIT, by using the patch from:   blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=26343.

 

However, the nano-x CPU usage is about 99%.

tested on svn trunk: uclinux-dist: Revision: 6612, linux-kernel: R4658.

The CPU usage showed by top is normal, about 2% when running the nxlib demo
