Ray,
> Does it also automagically set the bootcmd?
No it does not. Every other envs are OK. Except bootdelay.
I've finished the mtds and envs configuration setting in Debian, will post that set up shortly.

By the way,
The GPL source we have (link in this thread)
https://forum.doozan.com/read.php?2,78499,78654#msg-78654
https://opensource.actiontec.com/sg200.html)
can only build the SG200 u-boot. The build scripts were not set up properly to build the MI4242WR-I box. Even that, the result SG200 u-boot binary is not usable.
That with the fact that the stock u-boot name is uboot-revI-128MbFlash.bin, I think the GPL is not up-to-date for MI4242WR.
I could not find how any of the build script can be used to build a binary named uboot-revI-128MbFlash.bin.
So there must be a build script for MI4242WR-I , but it is not in the GPL source.

By the way, Verizon/Frontier used different firmware versions. Supposedly, Frontier had two Rev I units, one used 40.22.3.3 and the other used 52.0.7. The firmware were not interchangeable between the two units which suggests the use of slightly different hardware.

Cool! Thanks for the info. That makes more sense :) hopefully I can find more info about the Ethernet Switch in this GPL. Everything else is easy, but the GPL switch info is a musthave to figure out how to write DTS correctly.

Wow; I didn't know they had two revisions of the Rev. I! I bet that's why they skipped straight from I to K (the gpl source for the google fiber network box refers to it as mi424wr rev k)
This also explains why a month ago, when I built the all firmwares from the actiontec gpl site you linked, I couldn't get any 5x firmware to boot, but the 4x firmwares all worked as expected. I guess that reveals which model I have.

Also, the U-Boot source code and config is distributed only with the 4x firmwares. I can't UART boot yet, but once I have that set up, I'll see if I can get the U-Boot source code to build, and if their config is portable to the a modern U-Boot.

No, it is not. I've looked at the 5x FW briefly, it is the same as other Marvell u-boots. The information are valuable, though.

Here to recap our current envs settings to boot Debian on USB. And also set up mtd partitions to allow u-boot envs read/write acess in Debian.
Verify mtdparts in Debian:
# cat /proc/mtd
Set up envs area in Debian:
# cat /etc/fw_env.config

bodhi,
I've been looking as time permits, and wondering about a couple of things related to the "mvneta" driver issue. Bear with me, I'm not the embedded developer that you are.
I have found postings from years ago that suggest an issue with changes to the driver build. Those changes seemed centered around enabling or disabling buffer management in the driver. Apparently, all was good until somebody enabled it. Then the complaints rolled in, then it was backed out. That's one thing.
When I was using my MI424RW-Rev-I router with Verizon FiOS in front of my DD-WRT router, I was surprised that my DD-WRT upstream connection to the MI424RW was auto-negotiated to half-duplex. I could get a great speed-test result in that mode, but it was horrible when I forced DD-WRT to uplink using full-duplex. Unless I'm wrong, that suggests to me that the OpenRG-based firmware was operating with that driver set with buffer management disabled.
From a common-sense and performance perspective, disabling buffers and running half-duplex seems wrong, but it did work surprisingly well. And, with an older version of that driver than what's likely available now. What I don't know is if that can be set in the DTB. Thoughts?

Dave,
That error about buffer management was real. But it was a long time ago. Armada 370 does not have hardware buffer in the NIC, so there was a time when it was correct to remove it. In the latest kernel, it is not an issue anymore. Armada 370, 380, XP Socs all use the same BM code, and the lack of HW buffer for the a370 is taken into account. (Side notes: this might be a significant factor in lesser network performance comparing to the a380 or aXP).
Also, what you said above "MI424RW was auto-negotiated to half-duplex" should be relevant only for the SG200 model, because it has only 2 Ethernet ports. The MI424WR Rev I has a 4-port switch, so a different driver is used. The new Ethernet Switch driver is Marvell DSA (the old driver is obsolete and no longer usable). This was the reason I modified Claudio DTS to have the nodes for DSA.
I have not revisited this box since my last post above. So consider it still a work-in-progress regarding Ethernet. Wifi is working fine, though. So that's made it less urgent for me, since we can ssh into the box with Wifi connection.
Also, the IRQs workd differently in the the old kernel 2.6.x, so now with the new IRQ domain in the latest kernel, the lack of binding in the DTS seems to cause IRQs conflicts.
To summarize where my DTS version is:
- Need to implement nodes for pin controller. I suspect this is somehow relevant to IRQs assignments.
- Need to mach up the new DSA nodes in DTS with old switch driver settings in stock u-boot/kernel. But the pin controller must be done first before we can even debug this DSA switch.

All,
There was a request from one of our forum members to have the Aruba DTS. So that will be next on my todo task for this on this Avanta SoC.

bodhi,
Have you seen https://github.com/leitec/openwrt-staging/tree/avanta. In particular I believe some of the patches at https://github.com/leitec/openwrt-staging/tree/avanta/target/linux/avanta/patches-3.14 might be helpful.

bodhi,
I am winnt5 in earlier time. But I don't know what happens to my account.
I have a zte f660. That's the pon modem. I've tried Claudio's openwrt code and got two problems running it. One is ethernet problem and the other is serial console problem. The serial device's irq is disabled during booting. It make the console very laggy. But luckily, it boot successfully.

Thanks! that's definitely helpful. Looks like we use the same DTS/DTSI from Claudio Leite as a starting point already. However, seeing the whole patches might add more hints in figuring out some more details.
Unfortunately, OpenWrt is still on the same old switch driver, that's why they are at kernel 3.14. That driver has been removed from mainline long ago. This box right now has some unknowns: the MPP and pin controller, since Claudio did not have access to the datasheet back then.
Everything else is working, though. I can run the MI424WR-rev-I box and checked out Wifi, LEDs, MTD layout.... It is ffully functional as a NAS using Wifi connection.
So to recap what I mentioned before:
- Need to implement pin controller. I have not got enough free time to do this, but it should be doable just using what's in the DTSI. It might not be accurate, but we'll come to that. And perhaps I will be able to figure out this part.
- Need to mach up the new DSA nodes in DTS with old switch driver settings in stock u-boot/kernel.

I'm not sure I can help with OpenWrt. I've also been seeing the same IRQs problem, with Debian and the latest kernel 5.11.x. I hope to solve that after I implemented the pin controller.
The Ethernet problem is most likely because you are running a different hardware (with no switch chip). So the Aruba DTS that I just posted above (https://forum.doozan.com/read.php?2,78499,118759#msg-118759) might work better. The Aruba has 2 Ethernet ports.

bodhi,
Thank you, I will try that dts. Can I just replace avanta-mi424wr.dts with avanta-aruba-ap.dts? Which avanta.dtsi and avanta-6560.dtsi should I use? I am using 3.14 kernel, are later versions of dts compatible with older version of linux? I will try to update kernel version later.
I think drivers are all in the kernel. Openwrt may be similar to debian.

That might not work. Kernel 3.14 is too old. The DTS bindings are likely different. I compiled the aruba DTS using kernel 5.11.4-kirkwood-tld-1.

The same DTS will work on either Debian or OpenWrt. For your box and the Aruba, the Ethernet is simpler without the switch. The same avanta.dtsi and avanta-6560.dtsi are used for all Avanta boards.
However, I've also modified these 2 DTSI because of the old binding and some syntax will not work in new kernel.
Here is the latest for MI424WR-rev-I (I posted a while ago):

OK, I will try to update the kernel version. You said newer kernel version doesn't contain mvneta driver, but the newest dts are still using them. Will this cause any problem?
Do I need to modify any other code in kernel5.11 except dts?

The newest kernel does have mvneta.

Code change might be not be necessary. But I don't know yet since I have not read the whole OpenWrt patch (I was not aware that was fully intergrated until Ray pointed out above).

bodhi,
I noticed aruba dts don't define the phy number. It seemed to be necessary because I can't find any eth device using ifconfig when phy number is not defined in dts.
I don't know much about marvell's architecture. Is there many of phy on chip so that we should choose the right one connected to the rj45 port?

Yes. The Aruba DTS right now is only an initial version to see if you can boot the box. Ethernet need to be completed.

Definitely. It does need phy info. I will eventually add more to it after some one post the boot log.
Your zte f660 also need a different DTS. So let see if I can go back to the 1st post and see the specs for this box, and create a new DTS for it.

bodhi,
I packed all my f660 series boxes' information. Hope to give you some help.
I think f660 is using the internal switch of 88f6560. In official firmware, only when you plug the network cable into the gigabit port, the console will print this:

> Is it possible to try the phy number one by one?
Not a good idea. As I mentioned above, I'll try to create an initial DTS for this box. It should be simlilar to the MI424WR-rev-I DTS (since you identified that there is a Marvell switch 88f6560 inside). This made this more complicate than the Aruba.

The best way is understand the subject to learn by example. And I usually don't do tutorial for kernel or u-boot development (no time to do that). So when I post the DTS, you can read and see if you can get the idea how to modify it further.
The most important thing to do is to find the GPL source code for this box. The manufacturer must provide it when somebody requests, if it is not already available at their website. Without the GPL source, we would have to resorting to hacking each possible PHY, each possible GPIO.... take forever to do that!
