编译新版Q20路由器固件
2023-09-01 |Nonni | Digi

q20ttl.jpg

得到了一块JCG-Q20的板子,通电可用,不过直接编译Q20的固件刷入后无法启动,将本身的uboot换成pboot,还是不行,这种问题一般是交换机配置或者分区配置不对,研究了一下,更改了分区,成功启动。
准备nand分区表参考

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00080000 00020000 "Bootloader"
mtd1: 00080000 00020000 "Config"
mtd2: 00080000 00020000 "Factory"
mtd3: 00040000 00020000 "crash"
mtd4: 00040000 00020000 "crash_log"
mtd5: 00400000 00020000 "kernel"
mtd6: 07980000 00020000 "ubi"

新固件编译方法
新建型号

vi /target/linux/ramips/image/mt7621.mk

增加新设备定义

define Device/NonniWiFi
  $(Device/dsa-migration)
  BLOCKSIZE := 128k
  PAGESIZE := 2048
  UBINIZE_OPTS := -E 5
  KERNEL_SIZE := 4096k
  IMAGE_SIZE := 91136k
  IMAGES += factory.bin
  IMAGE/sysupgrade.bin := sysupgrade-tar | append-metadata
  IMAGE/factory.bin := append-kernel | pad-to $$(KERNEL_SIZE) | append-ubi | \
    check-size
  DEVICE_VENDOR := NONNIX.COM
  DEVICE_MODEL := NonniWiFi
  DEVICE_PACKAGES := kmod-mt7915e uboot-envtools
endef
TARGET_DEVICES += NonniWiFi

新建dts

vi /target/linux/ramips/dts/mt7621_NonniWiFi.dts

增加设备硬件定义,通过16进制计算分区,划分新分区布局

增加新设备网络配置

vi /target/linux/ramips/mt7621/base-files/etc/board.d/02_network

添加

NONNIX.COM,NonniWiFi|\

运行菜单配置,选择设备 NONNIX.COM-NonniWiFi,配置应用

make menuconfig

开始单线程啰嗦模式编译

make V=s -j1

编译好的固件,适合pboot刷入

openwrt-ramips-mt7621-NonniWiFi-squashfs-factory.bin
默认IP 10.20.30.40/16
默认密码 password
