change processor speed in DSP/BIOS config tool - ajs_edwards_uk - Feb 25 14:44:00 2002

Hi, I am trying to change the DSP speed in the DSP/BIOS config tool to 40MHz from 100MHz. When I save the change, it writes its config files, then when compiling it brings up errors about the syntax of the .s54 file which the DSP/BIOS config tool writes (improperly). How can I change the speed? I suspect it is making my program behave very erratically. |

Hi, Its easy to change the CPU clock easily using the internal PLL. You'll need to write the code for same however. Its also a good idea to verify the speed using a timer ISR just for surety. Refer to section 8 or reference set 1 on details about how to program the PLL.
