BeMicro SDK Simple Socket Server example problem semaphore

Hi,

I'm using the Arrow BeMicro SDK and we develop our application based on the Simple Socket Server example. We now need to port our application from SUPERLOOP to MicroC/OS-II version. While in DEBUG mode I have isolate that the program fail to create the 20th semaphore in targnios.c. (when I==19 in code below:

for (i = 0; i < GLOBWAKE_SZ; i++)

{

global_TCPwakeup_set.ctick = 0;

global_tcpwakeup_set.soc_event = NULL;

global_TCPwakeup_set.semaphore = ossemcreate(0);

if (!global_tcpwakeup_set.semaphore)

panic("globwake_semaphore create err");

}

ERROR MESSAGE ON JTAG UART:

panic: globwake_semaphore create err

dtrap - needs breakpoint

thanks for your help
