All,
It would be easier to build new u-boot if we can find the datasheet for the switch MV88E6171. My search has not been successful.

Hi
I installed the new kernel, built uImage using zImage and the .dtb and booted with the Dockstar u-boot.
Unfortunately it kernel-panics but it looks like a wrong address thing.
Excuse my ignorance, but why is the u-boot code from Linksys and the existing Linux support for the chip not sufficient to get a working u-boot? I understand that it may not be enough, I just don't understand why.
Personally you could give me the datasheet and I'd still be lost ;)

Excuse my ignorance, but why is the u-boot code from Linksys and the existing Linux support for the chip not sufficient to get a working u-boot? I understand that it may not be enough, I just don't understand why.
Personally you could give me the datasheet and I'd still be lost ;)

I think you're right! must be a wrong address. Let me post the DTS, and hopefully somebody will be able to spot my mistake.

Yes, it could be enough. However, as usually is the case, stock u-boot is quite a PITA to read because it is so old :) the old design has been gone from u-boot for many years. Datasheet has a formal format so useful info can be gleamed from there. If there is no datasheet, then we'll need to dig in the Linksys u-boot deeper.

Michael,
Which DTB are you using? did you try both version I've attached above?

Yes that should be the correct one. This PHY print is just for information logging and it caused a kernel panic!!!

NVM. I think I had found enough info for this switch chip. Probably just enough to initialize it to get ethernet working during boot.

Another version of the DTB to try with the test kernel. I also attached the DTS here.

FYI,
There is an ongoing re-architecture effort for DSA in the kernel. It will likely to be a significant change in kernel 4.6 or 4.7 about how we specify the DTS
So perhaps we should not spend too much time figuring out how to make the switch smarter. Using OpenWrt DTS, it is a dumb switch, but it's working. So let's not worry much about this.

Here is a test version for the new Linksys EA4500 u-boot.
I would like everybody who has this box to try this u-boot (it is not enough with one success, since I don't have this box yet, I will need all the info I can have).
Please try with kwboot:
Interrupt serial console at count down and:
- print the envs.
- ping the router or any node in your LAN
- Also observe the behavior of the LEDs during boot. How are they flashing? solid? ...
- And then let it boot all the way into Debian (the default envs will boot the Debian rootfs that is on an Ext3 partition which has been labeled rootfs)
Please post the entire serial console log here.

EDIT: Just tried booting this again with stock u-boot and it still kernel panics with the new .dtb :/

The LEDs are all off. The switch doesn't initialise and there's no link at any stage, in u-boot or in Debian
> - And then let it boot all the way into Debian
As you can see, we have the same issue as before. This is with the latest .dtb built into uImage and the latest test kernel (4.5.0) and the latest u-boot.
The obvious issue is "PHY reset timed out" just before egiga0 is "initialised"

Ah, sorry about that. I must have accidentally used the Dockstar one the 2nd time (when I pasted the logs) but the result is similar.
This is the output using the correct u-boot:

There is still one piece of information that I could not find: PHY_BASE_ADR. Not sure where the PHY base address of this switch. It could be 0x0A.

The new DTB can only be used with new kernel (tld-2.1), because it exposes the DSA switch with the added node, using the mv88e61xx driver. The OpenWrt DTS does not have DSA node (that's why the switch is a dumb switch). The new DTS was based on the Viper one that bobbafett posted.
In any case, the kernel panic in the "print" call made it impossible to verify if the new DTS is working or not. FWIW, your dmesg showed the normal probe output for DSA switch before this panic occured.

"root" is rarely if ever used in commercial routers, no common user knows what "root" is.
stock user is usually "admin" or "Admin"
and passwords are "admin" "1234" "0000" or similar.
according to wikidevi, that router's user/pwd is "admin" and "admin"

I'm out of luck! I think the previous owner has changed password. I'll have to wait to reset it in Debian.

I pulled the rootfs from a firmware image, but /etc/passwd and /etc/shadow both live in /tmp and I'm not sure how they're created. So unfortunately no luck there.
Amusingly, there are a number of comments in shell scripts like "TODO: Figure out what this does and why"
It's like they didn't even finish the product before it shipped :)

I've seen worse in other products, comments like "This would never work" :))
Re new u-boot:
The current problem I've found is the switch driver in main-line u-boot does not have full functionality! that why the test u-boot did not activate the ethernet PHY.

So far my current u-boot build works OK. The only thing remains not working is network during boot. This is uncharted territory, since we don't have a working Ethernet switch driver in main-line u-boot. I found a patch for the Marvell 6176 switch, but that is also not quite ready.

No it does not, if the switch is not active then everything is dead (at least that what it seems to me). We can't bring the PHY up since the PHY is in the switch (there is no separate network PHY like in a typical NAS, WAN port is one of the ports in the switch). It will need more works in u-boot to do what OpenWrt DTS does in the kernel for the driver to work.
Yes, I do agree we just need Ethernet, we could not care less if the switch is a dumb switch :) Once we can have that, the kernel will take care of the DSA part.

No it does not, if the switch is not active then everything is dead (at least that what it seems to me). We can't bring the PHY up since the PHY is in the switch (there is no separate network PHY like in a typical NAS, WAN port is one of the ports in the switch).

I'm looking for this MV88E6171 switch data sheet but can't find it! anybody has idea how to find?

best thing I find with some low-level info about these switches is the comments in this github https://github.com/mmilburn/marvell-switch
It seems to have more data than what I can see from linux mainline driver.
Backtracking the patch the guy talks about in his github (that is a broken link) I get here where the same guy is discussing the issue and posting more info with other devs. https://github.com/Chadster766/McWRT/issues/20

Looks like I've partially solved this Ethernet issue :) will do a little more testing to confirm. Yes, I've also read both threads above before.

I've adapted a driver patch that the author has tested on the mv88e6176 switch. And it partially works! The remaining issue is how to power up this mv88e6171 PHYs from a cold start.
Below is kwboot from a warm start, where stock u-boot has been used to boot the new kernel version 4.5.0-kirkwood-tld-1.1 (with the EA4500 DTS uploaded by Michael). The driver works in this warm start case, but when the box is cold started, there was no power to the PHY so the ports are all dead!
This is much similar to the NSA325 and NSA320s/310S problem with stock u-boot, where a PHY write sequence is needed to power it up. This was solved in the new u-boot for the network chip mv88e8138s.
Warm start with Ethernet cable on LAN 1 (port 0)
