    154154The U-Boot Bootloader by convention provides a {{{hwconfig}}} environment variable which is used by the firmware (before U-Boot is loaded and executed) to configure board options at power-up. These options can include things such as:
    155  * miniPCIe socket functions (ie PCIe vs mSATA vs USB 3.0)
     155 * miniPCIe socket functions (ie PCIe vs mSATA vs USB3.0)
    156156 * serial configuration (ie RS232 vs RS485)
    157157
     
    162162   - J9: PCIe
    163163   - J10: PCIe or SATA
    164    - J11: PCIe or USB 3.0
     164   - J11: PCIe or USB3.0
     165
     166Note that USB2.0 is routed to all three miniPCIe sockets always but as USB3.0 shares signals with PCIe you must choose between PCIe and USB3 on sockets that support USB3.
    165167
    166168You can get/set the {{{hwconfig}}} variable within the U-Boot bootloader but you must reboot the board for it to take effect as the variable is acted upon in the Secondary Program Loader (SPL).
