Openwrt Uboot Burn Write

Openwrt burning uboot need to be cautious, generally buy a uboot with immortal router again toss will be more safe, because

The Uboot partition is protected by the OPENWRT firmware, and routers with an undead uboot can be brushed firmware through the Web interface.

The legendary immortal Uboot can be found at the following URL:

So how did the Uboot burn? I summed up:

Here is a summary of the 4 methods, the first two methods are OpenWrt can open up, the latter two ways is openwrt hang off when used.

Of course, if even uboot are hung up, then only through other methods to brush the openwrt (such as the removal of Flash direct brush), the following is an example:

The 1th method is to use an SSH connection to put the firmware into a writable file system and brush it with a command.

Because SSH supports the transfer of files, it can be done with Winscp+putty.

The 2nd method by building an HTTP server on the computer, with the SSH command to let OpenWrt from the computer to firmware to the board writable file system,

and use the command to brush the person.

The 3rd method requires the router to be torn down, with a command to get the router to take uboot from the computer via the TTL line, and to use the command to swipe into the Uboot

The 4th method is the method of undead uboot, where the meaning of "immortal" is actually not to dismantle the machine to restore the OpenWrt,

This greatly facilitates the process of Daoteng. This uboot typically comes with a friendly web interface that uploads the Uboot file to the router via HTTP.

If you have doubts about the filesystem above the router, look at OpenWrt's official documentation:

I'm just here to introduce some general concepts, specific brush uboot operation can be seen here:
