Hello,
We have a C5515 EVM board and an EZDSP C5515 board. The same software that runs at a normal speed in the C5515 board when loaded in the EZDSP runs at a much lower speed. What could be causing this to happen? Is there anything that needs to be done in the EZDSP to run at a normal speed? When the sample software that came with the Code Composer for the EZDSP is loaded it also seems to run much slower than the original software that came alredy loaded in the EZDSP. Thank you. Regards, Eduardo
Hi Eduardo,When running code from CCS, the GEL file that is loaded with your target configuration typically initializes the PLL and system clock.You can verify this by modifying your target configuration (.ccxml) file so that it does not have a GEL file associated with it. Then see how quickly the program runs.During initialization of your code, you probably need to configure the PLL to provide faster system clock.See the CSL_PLL_Example from the C55x Chip Support Library.It is located under C55 Low Power Chip Support Library v2.50.00 CCS4\c55xx_csl\ccs_v4.0_examples\pll\CSL_PLL_ExampleHope this helps,Mark
