Openwrt 固件升级检查平台

发现

• 看起来openwrt会自己缓存一份hw，或者就在固件里，这和uboot里的关系不大

root@OpenWrt_SLboat_Mod:~# cd /tmp/
root@OpenWrt_SLboat_Mod:/tmp# sysupgrade openwrt-ar71xx-generic-tl-mr10u-v1-squashfs-sysupgrade.bin 
Invalid image, hardware ID mismatch, hw:07030101 image:00100101.
Image check 'platform_check_image' failed.

• 然后的当然了，你可以强制绕开它

root@OpenWrt_SLboat_Mod:/tmp# sysupgrade -F openwrt-ar71xx-generic-tl-mr10u-v1-squashfs-sysupgrade.b
in 
Invalid image, hardware ID mismatch, hw:07030101 image:00100101.
Image check 'platform_check_image' failed but --force given - will update anyway!
