UsbHost reference clock

I'm developing an application on the beagleboard for educational purposes.
I would like to know what is the USB Host reference clock, in order to study deeper the USB Host bus.

Does anyone know anything about it ?

Thanks in advance !



When i did “bitbake libgles-omap3”, the OMAP35x_Graphics_SDK_3_00_00_09 package was installed. but i am getting the below error. looks like pdsasm file alone is generated for x86. Because of which the package is not being built properly.
Can someone suggest where to look into to fix this issue ?
