TMS320F28069M: Change internal oscillator to external oscillator in motorware

Part Number:TMS320F28069M

Hi all,

I was recently trying to switch the internal oscillator to external oscillator in HAL_setupClks function. I needed to keep system clock 90Mhz as it is. I refereed few conversation in the forum regarding this. But did not worked.

So far I tried to mimic control suit XtalOscSel function in HAL_setupClks as below, 

CLK_enableCrystalOsc(obj->clkHandle);//enable

usDelay(1000);

CLK_disableClkIn(obj->clkHandle);

CLK_setOsc2Src(obj->clkHandle, CLK_Osc2Src_External);

CLK_setOscSrc(obj->clkHandle,CLK_OscSrc_External);

CLK_setLowSpdPreScaler(obj->clkHandle,CLK_LowSpdPreScaler_SysClkOut_by_1);

CLK_setClkOutPreScaler(obj->clkHandle,CLK_ClkOutPreScaler_SysClkOut_by_1);

But did not worked. Is there any example with external oscillator . Please help me to solve this.

Thanks.
