Adding OpenWrt support for Xiaomi AX3600 (Part 1)

Yes, I'm sure the problem is in qcom_q6v5_wcss, but you know, it's very complicated, I'm not sure if a working qcom_q6v5_wcss from qsdk could support the ath11k, right?

Do you have any datasheet for these chips?

Nope, just the kernel source from QSDK.

If you apply my qcom_q6v5_wcss.c file able and also enable

+CONFIG_QRTR=y
+CONFIG_QRTR_SMD=y
+CONFIG_QCOM_APCS_IPC=y

You sould get

Looks like scm is broken on mainline ipq8074 :confused: i guess we are stuck (i cant think of anything other than porting the qca drivers for the FW load and Q6 init)

No these messages.
I think you could push your code.
I'm not sure how many different between my code and yours.

Pushed my changes and ath11k FW package

I have ath11k starting, will push my changes tomorrow AM (getting late for me)

However it does hard reset the device after loading caldata.bin extracted from a QSDK build.

Great job!

All changed pushed to https://github.com/BuzzBumbleBee/openwrt/commits/ax3600

Should get you to the following point without caldata, but I get a crash as soon as the caldata is loaded.....

But Q6 is booted and working as expected and can now talk to ath11k via qmi / glink

Id get an MTD backup of ART 1st tho

Just wanted to say a massive thank you to @Apache14 , @gmzhuo , @efsg et al. for all of their hard work. It's looking really good, very much appreciated.

These chip id, socid looks strange.

And i'm still curious why we should use the address 0xd000000.

I have patched the wcss so you can try the lower region. Feel free to try move it back. I wont have chance to test that until after work.

I have started a general IPQ807x thread here now we have a lot more of the HW working :

Should help get others with IPQ807x based HW startes :+1:

Hi!
I managed to recompile the latest firmware (v67) using windows 10 linux subsystem.
I didn't lost SSH but I think the "phone home" stuff didn't work...

I don't see any changes in hosts, and I'm able to ping the sites that should be blocked.
Also the root password that I had set in v17 didn't change.

Could you help me? Can I run parts of the repack-squashfs.sh script in the router through SSH?

EDIT:
I was "following" the script line by line and cheking in the router if the changes were made, and besides roots password not changed (not a problem) I think this last step didn't work:

# as a last-ditch effort, change the *.miwifi.com hostnames to localhost
sed -i 's@\w\+.miwifi.com@localhost@g' $FSDIR/etc/config/miwifi

The current content of the file "/etc/config/miwifi" in the router is:

config miwifi 'server'
        option API api.miwifi.com
        option LOG log.miwifi.com
        option S s.miwifi.com
        option APP app.miwifi.com
        option STUN stun.miwifi.com
        option BROKER broker.miwifi.com
