ucos2 watchdog
hello frends,
I have some questions about ucos .. I have a little problems ..
I have Ucos book & source version 2.52 and arm port for ver 2.61 .. strange but can't download anywhere source 2.61 so .. works ..
but works with problems .. maybe the problem is b/c source is not
version 2.61 .. the problem is:
- two tasks: first blinks with the led, the second waits on semaphore if the new uart caracter came.
- two interupts: Tx witch handles tx circular buffer ..
- Rx which receives input char put it in in circ. buff. and post count semaphore ... the task which waits on sempahore pend that semaphore pick up the income char and put to the out tx buffer.
When i typing char's by hand everything is ok .. i give echo everything I typed, BUT when I send a big asci file the echo task
sometimes die , not evertimes but it can hapens... WHY ? can
any1 with arguments tell me why ?
best regards Keen
