Then, back in the uboot prompt, we run: tftp 0x82000000 firmware.bin 0x1000000. Note the file has 0 size and is read/write by everyone. cd /srv/tftp sudo touch firmware.bin sudo chmod 666 firmware.bin.

#U boot tftp serial

I'm not confident enough to test scenarios myself on my Archer C7, I do not have a serial connection to it and it's still under warranty (well, sort of.). The easiest way to resolve this is to create an empty file on the server, and let it be overwritten. This is all theoretically speaking, of course.

#U boot tftp update

There should be a step that requires to update to a stock TP-Link firmware version before starting the LEDE flash, just to ensure that the U-Boot is updated to include the updated TFTP recovery service (With TP-Link soft-region lock, that could pose more problems actually if there is no region-coded LEDE firmware).

There should be a mention about the version of U-Boot that it's available from.

This should be fixed in the documentation.Has the U-Boot TFTP recovery procedure been updated by TP-Link to have the ability to differentiate between firmwares containing U-Boot or not ? If that's the case, IMHO: What I'm pointing out is that the documentation tells us to use a stripped firmware (when U-Boot partition is present in it) when I found evidence that you can flash an unmodified stock firmware anyway. I'm just trying to understand how it works and maybe help in the documentation. I'm not looking to go back to stock TP-Link firmware. Is the TFTP recovery procedure able to detect that the downloaded firmware includes or not the U-Boot partition and deals with it accordingly since TP-Link includes it but not LEDE ? Is the documentation wrong about TFTP recovery ?Įdit (): Video was deleted on Youtube so I replaced by another copy of the same video. Through the serial connection we can see that the firmware downloaded via TFTP is 16384512 bytes, which correspond to the size of the unmodified recovery firmware he was using, the Archer C7 V2 v151014 so it does include U-Boot after all. I've seen a tutorial that uses TFTP to flash a firmware that does include the U-Boot partition.

To flash an original TP-Link firmware using TFTP, you need to strip the U-Boot section from it first, if it is included in the binary image.

To flash a version of LEDE using TFTP, you simply use the *factory.bin image.

The TFTP recovery service is provided by U-Boot, thus is third party firmware independent (only TP-Link officially modifies U-Boot).

Here are my actual understandings on TFTP recovery: I own an Archer C7 V2 currently running LEDE and I'm a little bit puzzled about TFTP recovery after reading the documentation on OpenWrt's Wiki.
