Microchip EV23X71A is a LAN9696 based EVB. Specifications: * CPU: Microchip LAN9696 switch SoC * DRAM: 1GB DDR4 * Storage: * 2MB QSPI NOR * 4GB eMMC * Networking: * 24 x 10/100/1000 RJ45 via LAN8814 Quad PHY-s over QSGMII * 4 x 100/1000/2500/5000/10000 SFP+ ports * 1 x 10/100/1000 management RJ45 via LAN8840 PHY over RGMII (U-Boot too) * USB: 1 x USB2.0 Type-A * Management via USB-C (MCP2200): * UART @ 115200 baud * GPIO-s for bootstrap, reset and clock selection * DIP switch for boostrap configuration * LED-s: * 2 per networking port (Green and Yellow) * Green status LED * Yellow reset LED * Hard reset button * Power: * 12V DC barrel jack * 48/56V DC screw terminal * Selectable via toggle switch * PTP support: * Sync-E DPLL ZL30732B to generate the board required clocks * Two SMAs for PTP and two for Station clock inputs and outputs * Two ITU-T G.8275-compliant RS-422 interfaces for PTP applications * External PoE: * Option for PoE add-on, like EV14Y36A (IEEE 802.3af/at/bt Type 4 standard com-pliant) * Option for external CPU control via SPI and PCIe Installation instructions: 1. Connect to UART via the USB-C port 2. Connect the management port 3. Boot and interrupt U-Boot 4. TFTP the OpenWrt initramfs image and boot it 5. SCP the OpenWrt eMMC GPT image to a running OpenWrt initramfs to /tmp openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img.gz And decompress it via: gzip -d /tmp/openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img.gz 6. Wipe eMMC with: dd if=/dev/zero of=/dev/mmcblk0 bs=1M 7. Flash OpenWrt eMMC image with: dd if=/tmp/openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img of=/dev/mmcblk0 After a restart OpenWrt will boot, and then regular sysupgrade can be used for upgrades.
