Switching from SuperWRT to OpenWrt


I am trying to replace superWRt by a proper OpenWrt image.
I can upload (using the superwrt boot web page) a squashfs image
I can access the device (AP143 platform) from UART

It looks like it boot at a weird address : 9f020000 instead of usual 9f050000 . I can not really change that (the superWrt loader seems locked)

Below the boot sequence

Any help welcome

You need to find or make a build that matches that board. Many TP-Link models have a 128k bootloader and thus boot to that address. In the ath79 system it is relatively easy to change the dts file to set the partition locations.

AP143 is ar71xx
Thatis the board : AP143
Not sure whan do you mean by "make a build that matches that board" ?

The "AP143" is suggested hardware design by Atheros, but manufacturers make slight changes with memory locations, LEDs, ports, etc.

ath79 is a new approach to AR71xx chips, so far it is found only in trunk and has not been ported to all the models in ar71xx but should be used when possible.

I'd make that even stronger, as, at least as far as I understand it, no submissions are being accepted for new ar71xx devices and the ar71xx platform will be deprecated at the next release with no further updates.

"Build that matches" the board means (among other things) that you've got the right devices on the chip enabled and attached to the proper lines, and drivers to match. That the partitioning is correct, cal data, MACs, and the like are properly extracted from the proper places, the kernel location, compression, and entry point all match the bootloader, and that bootloader args are ignored or modified when needed.


This is not really the point. I know ar71xx are not accepted, but once again, not the point here.

I am just trying to boot the device, a AP143 board, previsouly on superWRT

Then you either need a matching, functional mach file for ar71xx, or to port it to ath79. If you're going to take the time to do that, you might as well do it on ath79.

"AP143" is just an OEM reference design. Each manufacturer can and often does change it to meet their needs, both in hardware and in firmware. In some cases, the reference design itself is non-bootable.


@mk24 and @jeff,

Be advised, the OP's device has not yet been ported to OpenWrt: AP143 firmware spkg

This was covered in the previous thread. The OP doesn't [seem to] understand that a firmware has to be developed for OpenWrt; and despite this, will continue to insist you instruct on how to flash/boot it anyways.

It seems as if the OP believes you can just piecemeal a working image together from the /boot and root folder of another firmware. In the last thread, the OP insisted that I make a firmware; but never even provided information on the files. Perhaps you should ask the OP if they think this is possible; and if yes, why haven't those steps been undertaken themselves already.

(I directed my response to you; because he's requested I not speak to him again.)


@lleachii : your attitude is totally insane, please do not talk to me anymore

@ otehr : I finally managed to boot the device on AP143
Here the error I get from the boot log regarding the eth port:

[    0.837285] switch0: Atheros AR8229 rev. 1 switch registered on mdio-bus.0

@mk24 and @jeff

Feel free to inform him the OP this is because he booted from build from another board.

Now he has to fix the hardware problem.

@lleachii How to ban you from this site ?

  • You'll be banned first
  • I didn't talk to you (until you just addressed me)
  • I also answered what the PHY issue is, do you want help or not

@lleachii please focus on something else than my posts

@jeff Finally made it ! https://github.com/openwrt/openwrt/pull/2023
