Default Jumper and Pin Settings of the BOC for PCIe link

Hi,

in order to do a PCIe link between 2 EVMs (DSPC6678), i need to configure also the jumpers of the BOC.

So in my plate forme, each board has :

- its own Power supply,

- its own Emulator

- its own reference Clock

so i made the Jumper and Pin Settings by default, and i need to know the position ON is denoted by 0 or 1???

I assume you are talking about the Dual EVM BoC as follows:

The data manual (link below) mentions that "An on indication is denoted as “0” " on page 9.

The default jumper and pin settings should be fine for PCIe link, as there is a shunt installed on JP3 to disable the common clock. So the PCIe module on each EVM will use its own reference clock.

You can use common clock for both PCIe modules as well. Please refer to the BOC and EVM data manuals to see the details.
