DSP/BIOS not initialized, why?

Hello,

everybody!


I am working on dm6437 platform, and there's something wrong about my application.

I create an application project to receive data from UART0, which works in interrupt mode, and  UART0 interrupt is set up with DSP/BIOS.
When there are only tasks, such as TSK_idle and TSK_LedBlink, the program goes well, and can receive data correctly. When I remove the TSK_LedBlink, add a new task "TSK_Jpeg_Decoder",
then I run program, but the UART0 interrupt does not occur, and can not receive the data.

I halt the program, and open the DSP/BIOS Kernel Object Viewer (KOV). I find the DSP/BIOS is not initialized, such as follows:


I don't know why?
Would you give me some suggestions?

Best Regards,
Michael Lee
