From 51fe956c4fbd6ea78f46a4aa835f142e94f32cee Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Mon, 24 Dec 2018 15:20:25 +0900 Subject: ipq806x: add support for Buffalo WXR-2533DHP Buffalo WXR-2533DHP is a 2.4/5 GHz band 11ac router, based on Qualcomm IPQ8064. The U-Boot on WXR-2533DHP employs a complicated dual firmware protection scheme against corruptions of the kernel and rootfs images. See the notes in buffalo.sh for details. specifications: - Qualcomm IPQ8064 (384 - 1,400 MHz, 2C2T) - 512 MB of RAM (DDR3) - 256 MB of Flash (NAND) - 4T4R 2.4/5 GHz Wlan (QCA9980) - 5x 10/100/1000 Mbps Ethernet - 10x LEDs, 8x keys (6x buttons, 2x slide-switches) - 2x USB 3.0 Type-A - 12VDC/4A AC Adapter - UART through-hole on PCB - J3: Vcc, GND, TX, RX from USB port side - 115200n8 Boot instructions for the initramfs image: 1. Prepare the TFTP server with the initramfs image renamed to "wxr2300dhp-initramfs.uImage" and IP address "192.168.11.10". 2. Press the "AOSS" button while powering on the WXR-2533DHP. 3. Wait until the "Wireless" LED flashes before releasing the AOSS button. The WXR-2533DHP will grab the image from TFTP server and will boot it. Flashing instructions: To persistently write the firmware, flash an openwrt sysupgrade image from inside the initramfs, for example transfer via `scp root@192.168.1.1:/tmp` and flash on the device with `sysupgrade -n /tmp/`. Then wait ~120 seconds to let it finish the flashing process.
