Hi, a new/noob openwrt user here.

Could anyone tell me how hot AX300T normally runs with openwrt?

I flashed mine with the snapshot version and I configured it to be a "dumb AP" with an ethernet backhaul. It consistently hovers around 65 degrees while its CPU usage around 0-2%. Around that temperature over a long period of time (12+ hours), the Wifi (any bands) will become erratic and all clients connected to it experiences drastic slowdowns dropping internet speeds from hundreds of megabits per seconds to a hundred kilobits per second.

I honestly suspect its the heat that causes this or has anyone experienced this as well?

P.S. My Ax3000T lays on a flat table by itself without any other things around it. My other AP works fine in the same network. I also tested and confirmed that my Ethernet cable (between the APs) are fine.

Tested. I can confirm that it works!

Could you please run the following? (just to confirm the hardware of your router)

dmesg | grep -i an8855

dmesg | grep nand

HSNP · October 12, 2024, 2:16pm

Hi,

I recently flashed RD23 with ESMT chip, Openwrt ran fine until I rebooted it and it went to bootloop. I could restore it with Mifiwi repair tool.

Is there a way to fix this issue without changing the stock bootloader?

Thanks

Lexeyko · October 12, 2024, 2:26pm

It works. Thanks for your work! I look forward to official support for openWrt!!!

an8855 mdio-bus:01: configuring for fixed/2500base-x link mode

How should I understand this correctly?
Are all these ports 2.5G?

alexq · October 12, 2024, 3:08pm

No, ports in the AX3000T are 1Gb only.
The 2.5 Gbps is related to internal bus or interfaces between the AN8855 switch and the Filogic 820 CPU.

Previous versions of the AX3000T returns the same output:

root@OpenWrt:~# dmesg | grep -i mt7530
[    1.242411] mt7530-mdio mdio-bus:1f: configuring for fixed/2500base-x link mode

alexq · October 12, 2024, 3:45pm

So, there are 2 confirmations that AX8855 switch support works

@remittor , could you please create a PR with AN8855 support into the official OpenWrt repository?
So that it starts appearing in the official Snapshot images.

Lexeyko · October 12, 2024, 4:00pm

And finally, please, official repair of xmir-patcher, so that it could make backup copies...

Linaro · October 12, 2024, 4:15pm

It won't be accepted in its current form, otherwise I would have made this PR myself.

amnesia · October 12, 2024, 4:47pm

Hello @all ,

I'm currently at the

Change to OpenWrt U-Boot

point, but I couldn't found the uboot binary at https://firmware-selector.openwrt.org/?version=23.05.5&target=mediatek%2Ffilogic&id=xiaomi_mi-router-ax3000t .

Is there a stable version or only the unstable version from the snapshot version?

Regards

xury · October 12, 2024, 5:18pm

I confirmed its work with te AN8855 switch, but after few restart its switchet to bot from system1 partition and caused bootloop.
I tried use:

sed -i '/exit 0/i sleep 5\nfw_setenv flag_try_sys1_failed 0' /etc/rc.local

but it not helped. How to set bootloader flag? how to read them?

xury · October 12, 2024, 7:08pm

I found that in this version of uboot the flags flag_try_sys1_failed and flag_try_sys2_failed cannot be 0, so I set to 2:

sed -i '/exit 0/i sleep 5\nfw_setenv flag_try_sys1_failed 2' /etc/rc.local

and now after ten rebbots still is OK

Ser9ei · October 12, 2024, 8:22pm

About the bootloop issue with the new version of the stock firmware
(bootloader)

I have the script (bootcount + platforms.sh) in my build to properly update the boot flags (from boot env), but missed info about the issue from SNAPSHOT (absent in the 23.5 branch):
"mediatek: filogic: Update bootcount init script permissions" - https://github.com/openwrt/openwrt/commit/cb86e313d3ad6faf894b626bdd311fb106223ddf

I have uploaded:

fixed scripts (bootcount + platforms.sh)
https://drive.google.com/drive/folders/1eVqXs6FaiF8CJnyBST1wKLRs1Ym8jvAg?hl=en
fixed firmware
https://drive.google.com/drive/folders/1lyGyOxhoqlRwYa5ABKRrNvQh1oUl-ydP?hl=en

and update info repository about permissions (see step 5 in the README.md file)

Attention!
My build include fix for anti-bootloop & Winbond chip only, no changes for the ‘an8855 driver.

Feedback
Test passed for:

RD03 + ESMT
RD23 + ESMT
RD03 + Windbond

alexq · October 12, 2024, 9:26pm

It's not enough information to suggest something.

Before reboot, run the following to gain better insight into what is going on:

ubus call system board
fw_printenv

xury · October 12, 2024, 10:44pm

I know something more. After every boot even boot was successful causing flag_try_sys1_failed being increased. When flag value is 6 or 12 etc. bootloader trying boot from another partition and bootloop started.

Ser9ei · October 12, 2024, 10:45pm

FYI:
This build has the same issue, the script does not run when the router is booted (no execution rights).

And the script is different from mine, I haven't tested it.

xury · October 12, 2024, 10:47pm
