Standard OpenWrt on Chinese device with custom build: Ralink MT7620a + MT7610e evaluation board

dbrb2 · February 9, 2019, 5:25pm

Hi,
I have two Chinese devices running openWRT:

BusyBox v1.24.1 (2016-12-28 10:25:05 HKT) built-in shell (ash)
DESIGNATED DRIVER (Bleeding Edge, r47745)

Some more hardware info on the unit is given below. I am finding that the LAN connection is stable, and with just one device on the network, so is the wifi connection.

However, as soon as two devices of this type connect to the same wifi network, both units start loosing connectivity over wifi - with ping times into the 100s or 1000s or mS

I have spoken to the guys in China, but it is new year celebrations there at present. Based on the below, and the fact that there seems to be an openWRT build that matches the hardware as identified at the terminal, I have been trying to get openWrt running on it....but without much luck so far (see some dmesg dumps below)

Any ideas...?

I think you maybe able to update the firmware and obtain the latest one. But I am not sure which one would that be and if upgraded, it may solve the problem. However looking at the log your device has 128 mb of ram so it's more than enough. I'm not sure about the flash size but you may want to head over to documentation at openwrt.org and look for something similar to Ralink MT7620a.

dbrb2 · February 9, 2019, 6:18pm

Thanks - I did try that, but found that it was hanging on boot. However, I can rescue it again from the serial console....I'll give it a go and post the results here

They are running some kind of OEM firmware based on OpenWrt, but, as far as I know, "DESIGNATED DRIVER" was never a release. Trying to determine if you have a supported device (or a clone/rebrand of one) would be a good start at getting onto a current release, as I believe @ahmar16 suggested.

As I understand it, there have been many improvements in MediaTek support over the last few years, certainly since Linux 3.18.23

dbrb2 · February 9, 2019, 7:19pm

Yep, thanks

I tried:

https://downloads.openwrt.org/releases/18.06.2/targets/ramips/mt7620/openwrt-18.06.2-ramips-mt7620-mt7620a_mt7610e-squashfs-sysupgrade.bin

Since, based on what cpuinfo showed, this appeared to be what I was running, unfortunately that didn't work out too well. I can recover via the serial console luckily

I think it's unable to find/register the flash maybe and also the console is not able to bring up and some other pci devices so it fails. It's possible you are trying to upgrade from a wrong image.

Edit: Have a look at this ToH. It shows some devices with MT7620A SoC having DDR2 ram as your device. You should see which device is similar to yours and then try to flash the firmware.

Comparing the above to a successful flash of the official, but old, firmware (see below)

On the successful flash, I have:

[    1.080000] VFS: Mounted root (squashfs filesystem) readonly on device 31:6.

Above, with the failure, I have:
type or paste code here

[ 0.766222] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6

In the case of flashing to the openWrt formware, I was flashing the image:

https://downloads.openwrt.org/releases/18.06.2/targets/ramips/mt7620/openwrt-18.06.2-ramips-mt7620-mt7620a_mt7610e-squashfs-sysupgrade.bin

Which sounded like the correct image, but may in fact not be!

The 18.06 kernel never found the SPI port thus it was unable to do anything related to the flash.

slh · February 9, 2019, 7:41pm

I realize that you first need to get a working (real) OpenWrt version running on your device, but also make sure that both devices use unique MAC addresses for all their interfaces.

dbrb2 · February 9, 2019, 7:42pm

Cheers - good advice - I had checked that already actually, but it would have given many of the symptoms I was seeing. Unfortunately they were not the same

Trying a few other kernels, all of the 17.x releases gave the apparently even less successful below, at which point they hung as below.

...which do not have the slightest hint of OEM / Manufacturer / Model-number printed on the case?

Nothing that obviously relates to anything I have yet managed to tie down to an openwrt release

The issue I am seeing looks very similar to that reported here:

https://bugs.openwrt.org/index.php?do=details&task_id=1515&opened=1266&status[0]=

THough this is for slightly different firmware...

ahmar16 · February 10, 2019, 5:11pm

Have you tried this one? https://downloads.openwrt.org/releases/18.06.2/targets/ramips/mt7620/openwrt-18.06.2-ramips-mt7620-mt7620a-squashfs-sysupgrade.bin
I am not sure if this one works but since you dont know if your device is similar to any other device as I provided the link above, you will have to use the trial and error method here.

I am sure your device would be a Chinese-remake of some other device, you just have no idea which one. I suggest to look for similarities of your device with other ones having the same SoC and board. Look for flash size and type, number of ports, Wi-Fi etc.

Back in the day my ISP gave me a Dlink DSL-2750U (I dont remember the hardware version) but after a while that one apparently got fried somehow so ISP offered me a used router which apparently did not exist in the market and also ISP was using its own firmware, same one, as in Dlink. So as I wanted to change the firmware of the device I couldnt find any because the company existed only for hardware but they did not have any firmware for their products. I decided to flash it with Dlink DSL-2750 because the bootloader had a recovery mode enabled. I flashed it with a couple of DSL-2750 versions but none worked because the bootloader said illegal image and finally T3 worked, the router booted up normally and the router still works with that firmware. Only that DSL light does not work but all the other stuff just works fine.

dbrb2 · February 10, 2019, 5:19pm

Thanks - yes, I did give that one a go, as well as the version which explicitly mentions mt7610e - as you noticed, based on its name, and on what the board /thinks/ it is, we should be good to go.

However, the bug report linked to above, for a very similar sounding problem, was for a similar, but not identical problem. I have raised a ticket to see whether the patch that fixed the above might also be relevant here

dbrb2 · February 11, 2019, 6:35pm

A little more progress:

Though no more success booting

mk24 · February 12, 2019, 1:10am

There's no MT7610 chip on that board. Not that that would matter much, since the MT7610 is only a second radio for 5 GHz that attaches via the PCIe bus; you'd still be able to boot without it.

The other chip is a SI3226 analog phone adapter for the two VoIP lines. There appears to be no open driver for it.

Did you try the plain MT7620 firmware as @ahmar16 suggested? I think that is for the evaluation board that is basically only the MT7620 and some RAM and flash on a board.

dbrb2 · February 12, 2019, 6:29am

Hi,
Yes, I tried a few variations on the MT7620 firmware

Each gave me the below:

The partitioning is different. The stock firmware loads and boots from 0x60000. The OpenWrt firmware expects to be loaded at 0x50000. This apparently causes the OpenWrt routine which scans the firmware to find the root file system and dynamically add the rootfs partition to fail.

To use the OpenWrt build, you'd need to load it at 0x5000 in the flash instead of 0x6000. That may be possible by changing u-boot environment variables, or manually load and boot (to prove that it's going to work) or as a last resort replace the bootloader.

Dumping the 'factory' partition at 0x4000 (using md.b) and saving it to a safe place would be a good idea. Likely only the first 1k contains any data, but it is important to make wifi work properly.

Ok...I changed the partitions defined in the DTS file for the openWrt firmware to start at 00006 - and this then loaded fine:
