IPQ807x SoC Investigation / Status [WIP]

Hello all,

Im making this thread to make a central location for IPQ807x SoC information / status outside of the AX3600 thread. I have been working on the Xiaomi AX3600 device alongside @gmzhu , the current status of the HW is

Working

  • Linux Boot
  • Nand
  • LED's
  • Ethernet Ports (lots of thanks to @gmzhuo for getting this working)
  • Q6 firmware loading
  • ath11k loads / inits OK

Not Working / Not Done

  • PCIe (tho this could be just the AX3600)
  • Switch / VLAN setup
  • WiFi caldata extract from ART
  • Wifi AP (bss channel survey timed out)
  • NSS clocks (no idea why these fail to come online)

My staging branch is :

Yes this need a lot of clean up / improvement, but the core hardware is (seemingly) working.

I replace gcc-ipq8074.c to gcc-ipq807x.c
On my side, sometimes the remoteproc is not stable with gcc-ipq8074.c.

But there is still no packet with WiFi.

I also added WiFi caldata extract from ART.

Dose the ath11k support 802.11ax?
Why there's no HE Capabilities with iw list?

Are you able to get the AP enabled at all or even do an STA mode scan and get results ?

Yeah ath11k should support AX but im not convinced that either the firmware or ath11k itself is working properly with our SoC :confused:

Still can't get AP enabled or station scan.
Yes, I checked the code in mac.c, ath11k should support 11ax, but don't know why there's no HE capability.

I guess it's getting it's HT capabilities list from the Q6 side with a wmi call ?.

But as we can't get AP or a scan I think something more fundamental is wrong. I guess this is why ath11k isn't enabled yet on 8074 on mainline or QCOM staging tree.

Any one can help me?
What's this means?

ath11k solved. It's because of board info. I can sleep now.

Can you post the changes needed to get ath11k running. I have had no time to look at it over the weekend (DIY work around the house :smiley: )

I have already pushed.https://github.com/gmzhuo/openwrt

What bdwlan file did you use. In your tree it seems to be a symlink to board.bin ?

It’s from WiFi-ax-feed,and it’s the author of WiFi-ax-feed told me the issue should be the board file or cal file.

So your using board-sercomm-wallaby.bin.IPQ8074 as bdwlan ?

If so that's a little confusing as to why the one from stock fails.

Tested your latest changes, can confirm WiFi works AP and station scan.

But still no VHT or 160mhz capabilities showing, I am assuming that is a ath11k issue

I think it’s because of firmware.

Possible, but then it would be the same for all IPQ807X devices. I guess we need to find out whats actually supported in FW.

It could also be the board config file still not being 100% correct

FYI I have tested your branch with bdwlan.b292 (hash 131dcb827df00c0af5685d1e003a213f) on your branch and it works in the same was as the board file from the AX feed.

Which version are you get from?

From : miwifi_r3600_firmware_f7f3e_1.0.67.bin

I have extracted the firmware DIR and uploaded it here : https://drive.google.com/file/d/1ZnxXSdXFTzM7DnnRExOD0PYCxbarqkEe/view?usp=sharing

@Apache14 How did you get rid of the USB clock warning?

I finally got my AX3600 and have started working on it.
I have started from scratch and only using the upstream drivers, unfortunately I get the USB clock warnings and cant get into the shell despite NAND not throwing any warnings or errors.
