Summary: sport uart test case fails

Details:

sport uart fails to send file through /dev/ttySS0, host /dev/ttyS0 get nothing.

And if receive strings from host /dev/ttyS0, it isn't always getting the transmitted characters and would have unexpected character printed if the string is long.

Has been fixed yesterday,please update your code and have a try.

--- Cliff Cai 2008-02-20 22:13:01

Sorry ,a wrong post and action,this is for another bug...

--- Cliff Cai 2008-02-27 06:30:58

use timer to the bug caused by sport overrun,use timer to flip the tty buffer in

order to return from rx ISR quickly

--- Mingquan Pan 2008-02-28 02:18:33

Yes,fixed. Close.
