Hello My name is Tomasz, I have to make a connection between two DSP. I have to do it on two DSK C6711 , EVM 6701 or between EVM and DSK. I know that the easiest way to do it is by McBSP, but I think better solution is by using HPI and EMIF. Have someone done something like that? Could someone help me how to connect it or show me where can I look for information or examples how to do it? ...

Hello: Is there a way to tell using any registers if the DM642 internal PLL is locked, and if it is, at what frequency? There is a problem with the input clock causing unexpected behaviour of the EMIF (which runs off the PLL) - and I am wondering if this can be caught using any registers. Thanks ~ka
