Ipq5018: tri radio support for Zyxel SCR50AXE

For Developers
1

So I've got myself Zyxel SCR50AXE and I've flashed OpenWrt but there is no wifi visible in system and config/wireless is empty

OpenWrt bootlog

sharetext.io/3a9f4d5b

I'm using this branch to build my firmware github SCR50AXE
I've gained root access on OEM, grabbed logs and extracted required partitions.

OEM bootlog

sharetext.io/2561b8b7

Also extracted OEM .dtb

OEM dts extacted

sharetext.io/bcfc712b

My device is vanilla and not updated or registered to zyxel cloud
It seems there is no supported qualcommax device with three separate wireless chips yet. So this could be first one

Do you have your code somewhere around githubs?

Yes github link was posted in 1st post

In OEM fw looks like there are 2 pci wifis but three air interfaces. Is it DBDC?

6

WiFi devices are ipq5018 qcn6102 and qcn6122 for 6G. qcn6102 is visible as qcn6122 in OEM so two qcn6122 are logged
All current solutions for qualcommax are 2 radios or one + DBDC radio for 3-band support.

What do you get from iw phy and lspci -nn

my config is broken, so won't show anything. Looks like ath11k doesn't support triple radios in this configuration.
I will try to work out solution for 2.4 + 5 ghz for now.

Does "5ghz" gets to 6ghz channels (when it starts to work :wink: )

10

For now I've tested that 2.4+5Ghz or 2.4+6Ghz are fine after disabling 'q6_wcss_pd2' .In current config qcn6102 5Ghz got up then qcn6122 6Ghz stays down without own board-2.bin
