F2812 sample codes not working/building error (BIOS.cpuFreq is undefined)

Other Parts Discussed in Thread: TMS320F2812, SYSBIOS

Hi!

CCS5.3 90 w xds100v2 and f2812 dev borad.

CCS example/c2000/281x/tms320f2812/genaric example/hello exmaple

step 1: import OK.

step 2: build notok

warning: ti.platforms.tms320x28.Platform: "C:/ti/CCS5.3/xdctools_3_24_05_48/packages/ti/platforms/tms320x28/Platform.xs", line 268: ti.platforms.tms320x28.Platform.Instance#0 : The PLL type is not assigned, so the Boot module will not configure the PLL.
error: ti.sysbios.BIOS: "C:/ti/CCS5.3/bios_6_34_02_18/packages/ti/sysbios/BIOS.xs", line 209: ti.sysbios.BIOS : BIOS.cpuFreq is undefined. You must define the CPU frequency in your application configuration. For example, if the PLL is being configured for 100MHz, add this to your application configuration script: BIOS.cpuFreq.lo = 100000000;

What is the problem?

In first i install 097/setup_DSP281x_v120.exe Header files.

I try all example, but all wrong.

Thanks,
