Running Two Threads

Running Two Threads

[Raghu]

Hi All, 

I wanted a minimal command line interface in eCOS. So
I took the "Redboot" parser and command interface and
implemented some commands. I have a IXP425 based
board.

When I use the call "cyg_user_start" within which I
have all my command line processing, the application
works fine. 

But within "cyg_user_start" if I spawn a thread and 
due the command line processing within this thread, it
does not give any o/p on the console and the thread
seems to be suspended. 

But I have spawn a "dummy" thread, the dummy thread
runs fine. 

The "cyg_io_read" & "cyg_io_write" are documented to
be "blocking calls" but I tried with setting the
option, CYGOPT_IO_SERIAL_SUPPORT_NONBLOCKING in
ecos.ecc and also "cyg_io_set_config" but with no
significance. 

Any clues please ? TIA.
Regards,
Raghu
