RTOS/DRA71: BIOS cfg file

Part Number:DRA71

Tool/software: TI-RTOS

Hi

We meet a probleam aboout the timer.

(1) In the Uboot , the timer 2 was used .

(2) In the DSP(C66) project , the timer 2 was configured in the C66.cfg.

Some times , the modules use the timer2 would be timeout , we doubt that it confilect with the timer 2  in the C66.cfg.

I hav teh questions :

(1)What the timer configure in c66. cfg ued for?

(2)As in our project ,we also develop ipu ,why there are no timers configure in IPU.cfg?

(3) I had try to change the timer id in the c66.cfg, errors would happen during building. (.Instance#1 : Timer device unavailable.)

(4) Do you have some materials about the SYS/BIOS cfg files?
