WNDAP360 with current 22.03 trunk

For Developers
1

I have Netgear WNDAP360 access point with 19.07.10 and it works perfect. I understand that the 19.07 branch is already frozen and will no longer be developed. Therefore, I am testing trunk builds for this model. However, in the default version, everything is not so good there. At the moment I have 2 problems, one of which was solved. Tested trunk 20967.

  1. Natively, the device has a serial console with a default speed of 9600 baud. After loading and starting (tftpboot and bootm), the console starts working at a speed of 115200 from a certain moment (i think when bootconsole disabled) and you have to reconnect with a new speed, which is not very convenient.
    I found out that in 19.07 kernel options used MIPS_CMDLINE_FROM_BOOTLOADER, while current trunks use MIPS_CMDLINE_FROM_DTB.
    As a result, on 19.07, the kernel parameters look like this:
    board=WNDAP360 console=ttyS0,9600 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,7744k(firmware),64k(nvram)ro,64k(art)ro rootfstype= squashfs noinitrd
    For vanilla trunk 20967 like this:
    console=ttyS0,115200 rootfstype=squashfs,jffs2

After a little dirty hack in the form of setting a kernel parameter at 20967 MIPS_CMDLINE_BUILTIN_EXTEND i got this:
rootfstype=squashfs,jffs2 console=ttyS0,9600 rootfstype=squashfs root=31:03 init=/sbin/init mtdparts=ar7100-nor0:256k(u-boot),64k(u-boot-env),1024k(vmlinux.gz.uImage),6208k(rootfs),512k(var),64k(manufacturing-data),64k(ART)

And my 9600 speed working good from U-boot till root@OpenWrt:/#. Therefore, I have a question - is it possible to do the same more correctly through the config of the OpenWRT itself, and not the kernel. To make it easier to transfer between updates and new buildroots? I have suspicions that this is done through DTS, the question is how to include this in the OpenWRT config?

  1. After successfully winning at the speed of the console, a more serious problem arises. In principle, the console speed can be switched - it's okay and used rarely. There is a more serious problem - the ethernet port does not work. I successfully boot from tftpboot and bootm with kernel from 20967, everything looks fine. But at the same time, I cannot ping, ssh or access the web interface (I built with LuCI). For debugging, I added tcpdump-mini package - when pinging, it shows that arp requests are coming and arp responses are leaving, and that's it, nothing more:
ARP, Request who-has 192.168.1.1 tell 192.168.1.50, length 46
ARP, Reply 192.168.1.1 is-at 00:03:7f:e0:00:96, length 28

From the computer side, I receive messages about the unavailability of the host:

From 192.168.1.50 icmp_seq=1 Destination Host Unreachable
From 192.168.1.50 icmp_seq=2 Destination Host Unreachable

Perhaps the fact that the access point is connected through the POE-injector affects? The question then is - why does this not affect the tftpboot stage and on 19.07 branch? There may be a problem with the firewall or something like that - tell me how to temporarily disable it completely for debug. Perhaps the created br-lan bridge also affects? All settings are default. The same result occurs with images from the page https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=ath79%2Fgeneric&id=netgear_wndap360

you should be able to override the SOC wide *.dtsi include in ar7161_netgear_wndap360.dts, untested:

Tested, and it works! It would be cool to see this patch in the upcoming sources. I'm not a great git specialist, but I think the next git pull will give me a conflict with a manually patched file)

It remains to solve another problem with the Ethernet port, this is more important.

There is dmesg (with patched console speed and 20967 trunk), if it helps:

any news about gigabit ethernet? Iam facing now same issue, on gigabit poe (switch, injector) no network, on 100mbit works.

5

Wow, i changed on my PC speed to:
ethtool -s eth0 autoneg off speed 100 duplex full
and it start to works. But, gigabit eth is required option for 5GHz networks.

I also noticed, although I set full duplex on the computer, half duplex was set on the port of the access point itself. And no matter what speed - 10 or 100 megabits. It seems that with the new firmware, the access point does not know how to do full duplex? At the same time, when there is auto-detection of speed on the computer and point, it successfully sets 1000 full duplex:
[ 44.017303] eth0: link up (1000Mbps/Full duplex)
and this, when i put 100/10 full duplex on PC:

[  245.777198] eth0: link up (100Mbps/Half duplex)
[ 1070.577175] eth0: link up (10Mbps/Half duplex)

Perhaps we can solve this problem if we compare the DTS from another access point, which also has 1 port and is also on ar7161/ag71xx:

ok, btw, I noticed this one old topic, and there is mentioned about this issue and how to fix (something with pll for phy ?), I am not so familiar with the details, maybe as startpoint or doublecheck..

https://forum.archive.openwrt.org/viewtopic.php?id=43042&p=1
Post#18 + Post#19

Yes! Thanks for the tip! I fix it =)
I added
pll-data = <0x11110000 0x00001099 0x00991099>;
in eth0 section of file target/linux/ath79/dts/ar7161_netgear_wndap360.dts. Also i added fixed serial console speed 9600 in this file.
But now, i see no wireless interfaces, i keep digging =) Please check wifi availability on default openwrt builds (stable 22 and snapshot) - i tried both, but didnt see any ath9k wlans with ifconfig -a

I think DTS is fully incomplete, why 22.03 recommended for WNDAP360 with such failures?

8

huh, nice.
On my wndap360 with default install (frist time after stock fw), all ifaces are visible.
wlan0 and wlan1 are up and working, I can do wifi via 2.4g and 5g channels.
used this img:
https://downloads.openwrt.org/releases/22.03.2/targets/ath79/generic/openwrt-22.03.2-ath79-generic-netgear_wndap360-squashfs-sysupgrade.bin

only issue with eth0 (br-lan later) on gigabit-link at the moment.
Did wifi work, before your changes on pll->dts?

9

Hmm, strange.
I tried 19.07.10 my custom build (defconfing + some packages) - everything works.
Tried official 22.03.2 - serial and eth bug, but wifi works
Tried customize 22.03.2 via defconfig and selecting some packages - no wifi, weird console speed and no gig eth.
Tried customize 22.03.2 via openwrt default config with selecting ethtool+tcpdump+wpad_wolfssl - serial and eth bug, but wifi works.

Thats weird, defconfig produces fault .config which leads to not working wifi, or when im selecting WNDAP360 as single target i got not all needed packages?

Comparison of two modded configs: openwrt config.buildinfo and defconfig. In both of them, i select only single target device WNDAP360, LUCI, wpad-wolfssl (i need EAP), ethtool and tcpdump-mini:

We need to understand which of the options is necessary to include a device for a working Wi-Fi in the profile, since from my point of view, there are a lot of things that are not quite necessary in the config.buildinfo =)

BTW, i compiled new image with config.buildinfo where i select only WNDAP360 (no additional packages) + fixed DTS with serial 9600 and eth working:
first boot kernel image
sysupgrade to flash
patched dts

I checked this image and everything works: gigabit ethernet, console 9600 and wifi. So here the problem with a non-working wifi is not in DTS, but in the set of packages specified in the device profile WNDAP360.

Yep, i found that fcking bird - owl. In device profile of WNDAP360 there is DEFAULT_kmod-owl-loader=n, but it required to start wifi devices. I manually added CONFIG_PACKAGE_kmod-owl-loader=y and now everything works - gigabit eth, 9600 console and wifi! I dont know why, but in result config bin/targets/ath79/generic/config.buildinfo this option is not included. I would like to see all these changes in the next minor release, or at least in snapshots: DTS console/eth fixes, and CONFIG_PACKAGE_kmod-owl-loader=y in device profile.

Result images: first tftpboot image, image to flash
It seemed to me, but in my opinion these images works a little faster than the one that comes with the default config from config.buildinfo.

I would add one more tweak to get the power LED to go green for normal running in the DTS:
In target/linux/ath79/dts/ar7161_netgear_wndap360.dts
Replace the led-running variable with &led_power_green in the aliases section, and add this to the leds section:

led_power_green: power_green {
                        label = "green:power";
                        gpios = <&gpio 2 GPIO_ACTIVE_LOW>;
                };
