From 3c0e2aa63ef040dbfbd7fe5f05bc9dfaf5ae9242 Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Tue, 9 Apr 2019 14:48:31 +0900 Subject: ramips: add support for I-O DATA WN-DX1167R MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit I-O DATA WN-DX1167R is a 2.4/5 GHz band 11ac rotuer, based on MediaTek MT7621A. Specification: - SoC : MediaTek MT7621A - RAM : DDR3 128 MiB - Flash : NAND 128 MiB - WLAN : MediaTek MT7615D (2.4/5 GHz, 2T2R) - Ethernet : 5x 10/100/1000 Mbps - Switch : MediaTek MT7621A (MT7530) - LEDs/Input : 2x/3x (2x buttons, 1x slide-switch) - UART : through-hole on PCB - J5: Vcc, TX, RX, NC, GND - 57600 bps Flash instruction using initramfs image: 1. Boot WN-DX1167R normally 2. Access to "http://192.168.0.1/" and open firmware update page ("ファームウェア") 3. Select the OpenWrt initramfs image and click update ("更新") button to perform firmware update 4. On the initramfs image, perform sysupgrade with squashfs-sysupgrade image 5. Wait ~120 seconds to complete flashing Notes: - configuration in DeviceTree of DBDC (Dual-Band-Dual-Concurrent) mode for MT7615D chip is not supported in mt76 driver - last 0x80000 (512 KiB) in NAND flash is not used on stock firmware - stock firmware requires "customized uImage header" by MSTC (MitraStar Technology Corp.), but U-Boot doesn't - uImage magic (0x0 - 0x3) : 0x434F4D43 (COMC) - header crc32 (0x4 - 0x7) : with data length and data crc32 - image name (0x20 - 0x37) : model ID and firmware versions - data length (0x38 - 0x3b): kernel + rootfs - data crc32 (0x3c - 0x3f) : kernel + rootfs Signed-off-by: INAGAKI Hiroshi Reviewed-by: Sungbo Eo --- .../ramips/mt7621/base-files/lib/upgrade/iodata.sh | 55 ++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 target/linux/ramips/mt7621/base-files/lib/upgrade/iodata.sh (limited to 'target/linux/ramips/mt7621/base-files/lib/upgrade/iodata.sh') diff --git a/target/linux/ramips/mt7621/base-files/lib/upgrade/iodata.sh b/target/linux/ramips/mt7621/base-files/lib/upgrade/iodata.sh new file mode 100644 index 0000000000..d7a3477f0a --- /dev/null +++ b/target/linux/ramips/mt7621/base-files/lib/upgrade/iodata.sh @@ -0,0 +1,55 @@ +# +# Copyright (C) 2019 OpenWrt.org +# + +. /lib/functions.sh + +iodata_mstc_prepare_fail() { + echo "failed to check and prepare the environment, rebooting..." + umount -a + reboot -f +} + +# I-O DATA devices manufactured by MSTC (MitraStar Technology Corp.) +# have two important flags: +# - bootnum: switch between two os images +# use 1st image in OpenWrt +# - debugflag: enable/disable debug +# users can interrupt Z-Loader for recovering the device if enabled +iodata_mstc_upgrade_prepare() { + local persist_mtd="$(find_mtd_part persist)" + local factory_mtd="$(find_mtd_part factory)" + + if [ -z "$persist_mtd" -o -z "$factory_mtd" ]; then + echo 'cannot find mtd partition(s), "factory" or "persist"' + iodata_mstc_prepare_fail + fi + + local bootnum=$(hexdump -s 4 -n 1 -e '"%x"' ${persist_mtd}) + local debugflag=$(hexdump -s 65141 -n 1 -e '"%x"' ${factory_mtd}) + + if [ "$bootnum" != "1" -a "$bootnum" != "2" ]; then + echo "failed to get bootnum, please check the value at 0x4 in ${persist_mtd}" + iodata_mstc_prepare_fail + fi + if [ "$debugflag" != "0" -a "$debugflag" != "1" ]; then + echo "failed to get debugflag, please check the value at 0xFE75 in ${factory_mtd}" + iodata_mstc_prepare_fail + fi + echo "current: bootnum => ${bootnum}, debugflag => ${debugflag}" + + if [ "$bootnum" = "2" ]; then + if !
