Other Parts Discussed in Thread: SYSBIOS
Tool/software: TI-RTOS
Hi, we developed DSP program based on HelloWorld example to use the NDK. In my program, we send and receive data to and from FPGA, each time we will send the test results to PC via Ethernet. Here, we encountered a very strange problem: sometimes after serveral hundreds times, sometimes after ten thousands times, the sys/bios has the following exception:

It seems the sys/bios executed abort() function and exit.
Since I am not very familiar with SYS/BIOS, can someone help me or give me some suggestions?
Thanks.
