[openwrt] sysupgrade 명령어 사용

기본적으로 openwrt를 바로 다운받아 이미지를 만들었다면 방화벽 설정이 되어있다.

iptables 명령어로확인가능

iptables -F
tftp -g 192.168.100.10 -r openwrt-ramips-rt305x-r9dj202-squashfs-sysupgrade.bin -l /tmp/sysupgrade.bin
sysupgrade -v /tmp/sysupgrade.bin

이미지파일을 플래쉬에 직접 write 할 수도 있는데

mtd -r write /tmp/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin firmware

이것은 firmware block에 바로 write하므로 config가 저장되지 않는다.

sysupgrade로 업그레이드 하면 자동으로 config파일들을 백업하고 복원한다.

보드 config 는 UCI 를 이용해서 관리.

git clone git://nbd.name/uci.git
