OpenWrt新机的固件编译/定制

OpenWrt新机的固件编译/定制

目录

背景

手里有一台QCA的IPQ4019的路由器，为TP-Link的Deco M9 Plus 2.0。

查了下OpenWrt已经支持这个CPU了，便打算刷机。

关于如何搭建OpenWrt的编译环境，请见：

OpenWrt编译环境搭建 - 付时凡 - 博客园 (cnblogs.com)

硬件参数

已知参数：

硬件参数 型号/规格 说明
CPU IPQ4019
Flash Nand Flash(128M) Winbond W29N01HV
RAM 512M
PHY QCA8072
无线 2.4G+5G band1：IPQ4019内置；5G4：QCA9886 规格AC2200
USB 2.0 1个
蓝牙 CSR8811 UART总线
Zigbee EFR32MG SPI总线

软件修改

新增profile

工作目录应该在openwrt/target/linux/ipq40xx。所以：

cd openwrt/target/linux/ipq40xx

目前软件为Deco M9 Plus V2，结合之前以后的Deco系列命名：

$ rg deco
base-files/etc/board.d/02_network
129:	tplink,deco-m4r-v4)

base-files/etc/board.d/01_leds
201:tplink,deco-m4r-v4)

应该定为tplink,deco-m9plus-v2。

然后参考其他新机的提交，应该在以下文件修改：

$ rg ac2200           
image/generic.mk
193:define Device/asus_map-ac2200
200:TARGET_DEVICES += asus_map-ac2200

5:	asus,map-ac2200)

base-files/lib/upgrade/platform.sh

参考修改即可：

其中，DEVICE_DTS_CONFIG这个参数，需要结合M9Plus的启动参数来判断，日志会输出这个信息。

最关键的文件是dts文件，即设备树。

设备树

因为都是ipq40xx，所以很多和同个目录下的机型，是可以共用的，即头部包含的dtsi文件。

但特别需要关注几个硬件参数：

  • 内存
  • Flash大小/分区表
  • 无线接口
  • 有线接口
  • GPIO（LED+Reset）

内存

相对简单，基本上找个512M机型的dts文件照抄即可；这里参考的是GL的B2000：

	memory {
		device_type = "memory";
		reg = <0x80000000 0x10000000>;
	};

Flash/分区表

首先需要知道原有的分区，根据启动日志：

可以根据自己的需求来调整。

通常情况下，不修改uboot之前的分区。

无线接口

根据同目录下其他 AC200规格的写法，这里参考的是GL.iNet GL-B2200：

&wifi0 {
	status = "okay";
	nvmem-cell-names = "pre-calibration";
	nvmem-cells = <&precal_art_1000>;
	qcom,ath10k-calibration-variant = "GL-B2200";
};

&wifi1 {
	status = "okay";
	nvmem-cell-names = "pre-calibration";
	nvmem-cells = <&precal_art_5000>;
	qcom,ath10k-calibration-variant = "GL-B2200";
	ieee80211-freq-limit = <5100000 5400000>;
};


&pcie0 {
	status = "okay";
	perst-gpio = <&tlmm 38 GPIO_ACTIVE_LOW>;
	wake-gpio = <&tlmm 50 GPIO_ACTIVE_LOW>;

	bridge@0,0 {
		reg = <0x00000000 0 0 0 0>;
		#address-cells = <3>;
		#size-cells = <2>;
		ranges;

		wifi2: wifi@1,0 {
			status = "okay";
			/* Bootlog shows this is a 168c:0056 - QCA 9888v2 */
			compatible = "qcom,ath10k";
			reg = <0x00010000 0 0 0 0>;
			nvmem-cell-names = "pre-calibration";
			nvmem-cells = <&precal_art_9000>;
			qcom,ath10k-calibration-variant = "GL-B2200";
			ieee80211-freq-limit = <5450000 5900000>;
		};
	};
};

有线接口

&swport4 {
	status = "okay";
	label = "eth2";
	nvmem-cell-names = "mac-address";
	nvmem-cells = <&macaddr_gmac1>;
};

&swport5 {
	status = "okay";
	label = "eth1";
	nvmem-cell-names = "mac-address";
	nvmem-cells = <&macaddr_gmac0>;
};

注意修改对应的MAC地址。

GPIO

两类：

  • LED

    	leds {
		compatible = "gpio-leds";
		power_red: red {
			label = "red:system";
			gpios = <&tlmm 0 GPIO_ACTIVE_LOW>;
		};

		power_green: green {
			label = "green:system";
			gpios = <&tlmm 1 GPIO_ACTIVE_LOW>;
		};

		power_blue: blue {
			label = "blue:system";
			gpios = <&tlmm 2 GPIO_ACTIVE_LOW>;
		};
	};

  • Reset Button

    	keys {
		compatible = "gpio-keys";

		reset {
			label = "reset";
			gpios = <&tlmm 18 GPIO_ACTIVE_LOW>;
			linux,code = <KEY_RESTART>;
			linux,input-type = <1>;
		};
	};

至此，便可以通过：

make menuconfig

选中tplink,deco-m9plus-v2机型，然后编译。

编译后的固件：

$ ls bin/targets/ipq40xx/generic/ |grep m9
openwrt-ipq40xx-generic-tplink_deco-m9plus-v2-initramfs-recovery.itb
openwrt-ipq40xx-generic-tplink_deco-m9plus-v2.manifest
openwrt-ipq40xx-generic-tplink_deco-m9plus-v2-squashfs-factory.ubi
openwrt-ipq40xx-generic-tplink_deco-m9plus-v2-squashfs-sysupgrade.bin

刷机

参考另一篇文章：

uboot相关指令 - 付时凡 - 博客园 (cnblogs.com)

这里只记录指令：

擦写root.ubi：

nand erase 0x900000 0x7680000 && setenv serverip 192.168.0.66 && setenv ipaddr 192.168.0.171 && tftpboot root.ubi
nand write 0x84000000 0x900000 0x1500000
re

改写bootcmd：

setenv bootargs 'ubi.mtd=ubi root=/dev/ubiblock0_1 rootfstype=squashfs,ubi'
setenv set_ubi 'set mtdids nand0=nand0; set mtdparts mtdparts=nand0:0x7680000@0x900000(fs); ubi part fs'
setenv bootkernel 'ubi read 0x84000000 kernel && bootm'
setenv my_boot 'run set_ubi; run bootkernel'
setenv bootcmd 'run my_boot'

问题修复

启动后QCA9886未正常启动，报错如下：

[   11.918714] ath10k_pci 0000:01:00.0: Failed to find firmware-N.bin (N between 2 and 6) from ath10k/QCA9888/hw2.0: -12

应该是需要选中QCA 9886相关的package：

CONFIG_PACKAGE_ath10k-firmware-qca9888=y
CONFIG_PACKAGE_ath10k-board-qca9888=y
