Hi,
1) Can any one help me out to know , what clock frequency is used ?
> 200MHz
2) what is the minimum count in ns?
> 5ns
If we use a AM3359 timer what will be maximum frequency 24MHZ or 100MHZ?
>Its 24MHz if crystal used is 24MHz
You can use the BIOS timestamp API for DMTimer, details here - rtsc.eclipse.org/docs-tip/Using_xdc.runtime_Timestamps
