Adding OpenWrt support for Xiaomi AX3600 (Part 1)

robimarko · 2022-01-30T11:46:28.768Z

I personally don't see a point in that until networking without offloading fully works.
But that's my view, as always anybody is free to do whatever they want.

vit0r · 2022-01-30T12:46:45.863Z

We really need it to work properly without NSS/ECM offloading if we want to have any chance of upstreaming the AX3600 (or others) into OpenWRT. This is the moment that long term thinking must kick in, but I do admit it's not my call to make (i.e., I'm not pulling any weight here), and am generally biased towards having things merged into the upstream as soon as feasible for that long term support.

Just a quick follow up: it's working fine with builds from https://github.com/ns2switch/ipq807x-openwrt-builder (thanks @lokisp), so I'm definitely building it wrong.

Is there any needed specific configuration? I'm currently only changing "Target System" and "Target Profile" from default to match my device.

ronison · 2022-01-30T14:20:38.991Z

You have to set NSS-DP.

lokisp · 2022-01-30T14:23:54.971Z

You can find https://github.com/ns2switch/ipq807x-openwrt-builder/releases/download/ipq807x-latest%40v2/config.buildinfo the config used in the compilation

So some observations, and consolidation of info from across this thread that seems to be going well for me that this point, on my AX3600, running the latest (as of Jan 29th) Robi K5.15.15 codebase. It is acting as the main router against a Cable Modem which is bridged:

Memory seems to be behaving much better now with the 512MB patch in place.at 13 hours uptime, the device is sitting at 128MB free out of 407.75MB total.
I was having the issue where some wireless clients couldn't connect/transition/use the internet. I had forgottent hat I had read about this in another thread, and completely missed that you need "qca-ssdk-shell to workaround the issue. I have included my build config below.

-- I have Included in the startup->local startup the below which automatically creates the appropriate shell script in /tmp and sends it to background on startup. So far since adding, the wireless inability to connect to internet issue appears worked-around:

echo '#!/bin/ash' > /tmp/wifi_transition_workaround.sh
echo 'function flush() {' >> /tmp/wifi_transition_workaround.sh
echo 'ssdk_sh fdb entry flush 1' >> /tmp/wifi_transition_workaround.sh
echo '}' >> /tmp/wifi_transition_workaround.sh
echo "IFS=$'\n'" >> /tmp/wifi_transition_workaround.sh
echo 'logread -f | while read line; do'  >> /tmp/wifi_transition_workaround.sh
echo 'if [[ "$line" == *"AP-STA-"* ]]; then' >> /tmp/wifi_transition_workaround.sh
echo 'flush </dev/null >/dev/null 2>&1' >> /tmp/wifi_transition_workaround.sh
echo 'fi'  >> /tmp/wifi_transition_workaround.sh
echo 'done'  >> /tmp/wifi_transition_workaround.sh
echo 'exit 0'  >> /tmp/wifi_transition_workaround.sh
chmod 777 /tmp/wifi_transition_workaround.sh

 /tmp/wifi_transition_workaround.sh &

Again, the above will require qca-ssdk-shell to be included in the build.

In /etc/config/wireless make have manually added to radio 1 and radio 2 (I have 802.11r set via Luci, so just noting what I've added manually):

I answer myself. After verifying the packages, it was by selecting the kmod-dm kernel option in network. Now I was able to compile 5.15 for testing.

MAG · 2022-01-31T08:09:37.609Z

Good afternoon. Tell me, where can I get the openwrt_core files for the 5.15.15 kernel, otherwise I find it only under 5.15.13, they do not fit.

andreacasarin · 2022-01-31T12:04:26.839Z

It's working! Thanks a lot.

I'm a dev myself, albeit I have no embedded device experience. Is there something I can do to help here? I'd love to see this merged.

thorsten97 · 2022-02-01T11:10:05.568Z

@robimarko I installed your current 5.15, it runs very good. One thing I noticed is that the ethernet ports are connected with 100mbits only. Is there anything in the config I need to tweak to get gigabit enabled?

robimarko · 2022-02-01T11:13:40.482Z

Not really, it should just work.
There are others using it on AX3600/AX6 so they can confirm this as bug or not

Edrikk · 2022-02-01T11:56:42.135Z

My AX3600 works out of the box. I have the WAN port connected as well as one of the LAN ports (which goes to a Gigabit switch).

If needed my .config is above.

dspalu32 · 2022-02-01T12:23:39.477Z

AX3600 ethernet auto negotiation is working OK for me on 5.15: 1000 on some ports, 100 on others; always appropriate for the connected devices.

thorsten97 · 2022-02-01T13:49:01.967Z

It was only a cheap usb-ethernet adapter that is misdetected as 100mbit instead of 1 gig. False alarm from my side! Thanks for the great work!!!

csharper2005 · 2022-02-01T19:32:40.924Z

Hi guys!

First of all - WiFi is great, thanks!

Is it possible to make 96 Mbit max speed instead of 72 Mbit for 2.4 802.11n clients without MIMO? This was possible on stock. Something like qam256 if I am not mistaken. May be some kind of patch is necessary?

mapB · 2022-02-01T22:06:05.592Z

Could someone of the AX9000 owners do some "quick" tests removing NSS packages from 5.10 branch except NSS-DP and check if the wired networking issue appears? or.. get the 5.15 @psi-c attempt to include NSS-DRV and see if wired networking issue is fixed? This would be a try to discard that the issue is related with other NSS packages by some kind of black magic.

I have an AX3600 and cannot try it by myself. @kirdes if you do not mind... (I do not want to robi get mad )

I have a different device that has the same issue as the AX9000. Using nss-dp only works fine on 5.10.

rid · 2022-02-02T07:33:09.563Z

In my case, having 1Gb/300Mb connection I get half of the speed.

plikmuny · 2022-02-02T07:50:51.847Z

I flashed the largest firmware Openwrt from Robimarko. There i have only 12mb space for software installation which i feel very less.
Is there anything i can do to increase this space to around 100mb atleast??

snoova · 2022-02-02T11:49:09.992Z

Hey guys,

today is the day, i want to flash my AX3600 with the last @robimarko release (15 Dec 2021).
I followed the instructions from https://openwrt.org/inbox/toh/xiaomi/xiaomi_ax3600.

downgraded
got ssh access
copied the "openwrt-ipq807x-generic-xiaomi_ax3600-squashfs-nand-factory.ubi" to tmp.

I'm stuck within the flashing part:

nvram get flag_boot_rootfs

returns 0 (so in my understanding I have to flash mtd13 first).

ubiformat /dev/mtd13 -f /tmp/openwrt-ipq807x-generic-xiaomi_ax
3600-squashfs-nand-factory.ubi -s 2048 -O 204

returns: "ubiformat: error!: VID header offset has to be multiple of min. I/O unit size"

Any ideas to help me out.
