For the Joule module, it's advertised to have a PCIe-x1 interface multiplexed with USB3, Port1. Has this interface been tested, and is it supported? It is not mentioned in the expansion board design guide.
We would like to use a PCIe Packet Switch to two downstream PCIe devices: GbE and SATA. Since the diff pairs are multiplexed, how do you set it for PCIe?
Thank you for your interest in the Joule platform.
Yes, there’s a PCIe slot in the Joule, however, the current BIOS doesn’t enable the connector so it would be necessary a new BIOS which is currently not available and there’s no ETA for it yet. If I’m not mistaken some months ago another user used a custom carrier board along with the Joule and apparently was able to edit the BIOS to enable the PCIe connector.
