I noticed that in the pin list of Jetson nano there is a SDMMC, I want to konw:
does this interface share the same physical interface with SD card on nano board?
If the answer of 1) is yes, When I use the production nano board(with eMMC), can I use SDMMC interface for other purpuse? such as connect to WIFI module.
Also a question about PCIE:
can the PCIe interface support 4x1 lane or 2x2lane? or only support 1 device? except use PCIe switch.
