P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion headers. Currently, due to U-Boot's level of support for Tegra186, the only features supported by U-Boot are the console UART and the on-board eMMC. Additional features will be added over time. U-Boot has so far been tested by replacing the kernel image on the device with a U-Boot binary. It is anticipated that U-Boot will eventually replace the CCPLEX bootloader binary, as on previous chips. This hasn't yet been tested.
