program not stable

Started by Yong Yang April 19, 2004
Hi, all

I am using TI DM642 to develop a video codec. I need to communicate with PC to
read/write encoded or decoded video stream via USB JTAG or TCP/IP Ethernet.
Sometimes my program runs very well. But sometimes it does not run correctly,
with problems such as TCP connection fails, or the encoded file written to PC
hard disc via JTAG can not be decoded. I always spend lots of time to reset the
DSP board, restart the PC or reload the program to get it run correctly. It
seems my program on DSP is not stable at all. However, my codec has no problem
at all on Windows Visual C++ platform before ported to DSP. Any possible reasons
for it? Hope someone can answer.

Thank you
Yong
