multitasks with DSP/BIOS

mohammed maktite

hello everybody,

i am trying to write a Matrix multiplication program with DSP/BIOS using a couple of tasks. I have created tasks within DSP/BIOS configuration, i linked them to functions, and i gave them different priorities . The program compiles correctly, but when i run it, no task is executed and the program does nothing. I left main funtion empty. The program contains no SWIs, no HWIs, just tasks. Someone can tell me what could be the problem? Should i define some kind of program entry or something? PLz help.

thanx in advance.

Mohammed,

Is the BIOS schedular started? BIOS_start() needs to be called in the main() to enable the schedular, which will then schedule the tasks.

Regards,

Nag

thank you Nagabushan,

in fact ,i had a printf() inside my program, which caused the problem. When i commented it, the program was fixed, and it runs now correctly even without the BIOS_start() instruction.

thank again for you for your reply.
