Adding OpenWrt support for Nokia Airscale AC400i

2in2 · February 3, 2023, 9:09pm

Not sure, if they would. A bunch of other devices also have it set (probably because of internal switches), but from what I can see, there really isn't a way around it, even in the OEM firmware it's broken.

This may explain why I could see no web interface with these, when using my ancient 100BASE-T USB Ethernet Adapter (the link is established successfully, but that just means talking to the PHY, not GMAC)...

So there might indeed be missing some wiring on the PCB if this never worked in OEM, similar to the microSD.

Just leave a short note about these in the PR, the rest should be fine

Adds support for the Nokia Airscale WI4A-AC400i Access Point. The device doesn'…t really exist outside of public infrastructure, so no public page about it exist. But can be looked up using the FCC ID: [2AD8UFZCWI4A1](https://fccid.io/2AD8UFZCWI4A1) Hardware: ``` SoC: Qualcomm IPQ8065 RAM: 512 MB DDR3 Flash: 256 MB NAND (Macronix MX30UF2G18AC) 4 MB SPI-NOR (Macronix MX25U3235F) WLAN: Qualcomm Atheros QCA9984 - 2.4Ghz Qualcomm Atheros QCA9984 - 5Ghz ETH: eth0 - POE (100Mbps in U-Boot, 1000Mbps in OpenWrt) eth1 - (1000Mbps in both) Auto-negotiation broken on both. USB: USB 2.0 LED: 5G, 2.4G, ETH1, ETH2, CTRL, PWR (All support green and red) BTN: Reset Other: SD card slot (non-functional) Serial: 115200bps, near the Ethernet transformers, labeled 9X. Connections from the arrow to the 9X text: [NC] - [TXD] - [GND] - [RXD] - [NC] ``` Install instructions are in the commit description and on the [forum](https://forum.openwrt.org/t/adding-openwrt-support-for-nokia-airscale-ac400i/78356/59?u=2in2). Notes: - Auto-negotiation is broken in U-Boot and OEM firmware, so both ports are forced to run at 1000Mbps. The POE port runs at 100Mbps in U-boot. - The SD card slot is also non-functional (just like in the OEM firmware). - The NAND chip is split into two partitions inside U-Boot (PartA and PartB), we are installing OpenWrt onto PartA and leaving PartB alone, so restoring the OEM firmware, is as easy switching the boot partition.

support have been added finaly! have someone done some further testing ?

2in2 · March 25, 2023, 8:29pm

I'm currently using the device.
It works about as well as I expected it to.
There are still some weird quirks, if you fiddle with the power for a bit too long,
but otherwise works very well.

What speed You have over 5GHz? 80 or 160MHz channel?

2in2 · March 25, 2023, 9:28pm

So, from what I tested around 300Mbps download, but if you use the NSS patchset you can probably get more.
Also 160Mhz doesn't work, but 80+80 should work.

to load image into ram is simple way

Transfer initramfs image to device
( nokia_ac400i-initramfs-fit-uImage.itb
Tested using TFTP and a FAT-formatted USB flash drive.
For USB run
usb start
fatload usb 0:1 0x44000000 nokia_ac400i-initramfs-fit-uImage.itb

after this type bootm and hit enter .

"The QCA9984 also supports 160MHz and 80+80MHz channels to double capacity at close range" this is writen on qualcom support site, i'll check it when i get back home.

2in2 · March 25, 2023, 11:14pm

The chipset itself does support it, yes.
But the device is only rated for VHT80+80 (looking at the FCC data).
And yeah, you can select 160Mhz, but the radio stops working.

On lastest snapshot this ap are running nicely, it links at 1300Mbps or sometimes more, 160MHz width works good but speeds are rather poor like 300Mbps tcp on one client with firewall disabled and packet stearing enabled.

2in2 · June 20, 2023, 11:00am

I got around 400Mbps.
And yeah, that's to be expected.
To get more out of it, we would need to make a NSS build.
I gave it a shot, but couldn't do it.
I only got 1 NIC to show up in the OS, but it refused to link up.
So, I gave up on it for now.
