git clone失败

因为网络环境的不同，很经常出现https不能clone,git可以clone通过https://git.openwrt.org/project/rpcd.git clone一直失败，改成gitpackage/system/rpcd/Makefile PKG_SOURCE_PROTO:=git-PKG_SOURCE_URL=$(OPENWRT_GIT)/project/rpcd.git+PKG_SOURCE_URL=git://git.openwrt.org/project/rpcd.git PKG_SOURCE_SUBDIR:=$(PKG_NAME) PKG_SOURCE_VERSION:=73aea9b8b621a1ce034bc6ee00c9d058a40c8a3d PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION)-$(PKG_SOURCE_VERSION).tar.gz

make成功却不生成openwrt-ramips-mt7628-mt7628-squashfs-sysupgrade.bin

查看openwrt-sdk/target/linux/ramips/image/Makefile 可知SDK可以支持最大32M的flash，默认选择的是8M的，因为增加了很多软件包导致image的大小超过8M，所以不能生成sysupgrade.bin。将默认的Default8M改成Default16M即可以了

Image/Build/Profile/MT7628=$(call BuildFirmware/Default8M/$(1),$(1),mt7628,MT7628)

改成

Image/Build/Profile/MT7628=$(call BuildFirmware/Default16M/$(1),$(1),mt7628,MT7628)

硬件改成8Mflash

最后把703N_8M.bin写入8M flash，再把这个flash焊在板上就可。分析：1.升级固件不会升级art和uboot2.固件不会有4M或者者8M之分，但假如固件大小超过了4M，必需使用8M的flash。3.uboot能够自动识别4M或者是8M flash。但要求：当使用4M flash时， art存在地址为0x3f0000，长度为64K连续空间中使用 8M flash，art存在0x7f0000，长度为64K连续空间中。4.不论是4M还是8M flash boot的起始地址相同
