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
