Adding Extreme AP3915i/AP7632i support

For Developers
1

Hi,

I have a lot of AP3915i-ROW and some AP7632i-RW APs, which are802.11ac Wave 2 2x2:2 APs based on Qualcomm IPQ4029 with 512MB of RAM and 512MB of flash. IPA4029 is already supported by OpenWRT for https://openwrt.org/toh/aruba/ap-303h

They have a single gigabit ethernet port and only needs 802.3af PoE (it can also take 12V DC). There's an RJ45 serial port which works with a normal cisco console cable at 115200bps (which is good because it has T8 security Torx screws), there's also what looks to be a 4 jumper serial header inside. One button, four LEDs. The bootloader can be stopped (it'll ask for the default credentials, admin/new2day) I'll attach a boot log in a reply.

I'm happy to post some to developers interested in adding support, or working remotely to test images.

This is the FCC version but it looks the same as the ROW:

Hi trs80

What Openwrt-image did you install on the AP3915i?
The Aruba AP-303H Image?

4

Nothing, that's the vendor firmware. The offer to post some APs to someone who can add support is still open.

Ok
I found a hint for the WS-AP3915 in the master image on github.

In package/firmware/ipq-wifi you find board-extreme-network_ws-ap3915i.qca4019.

Does that mean that openwrt basically works if you compile the github-master?

6

Yes, looks like support for it was added in September: https://github.com/openwrt/openwrt/commit/e16a0e7e8876df0a92ec4779fe766de1a943307a

7

I went to build it and it's been disabled because it's not converted to DSA:

I'm trying a build of 132545785bbbe50c4403640153b686c3b75b63a8 which is just before it was disabled.

8

My build failed with

ERROR: Input tree has errors, aborting (use -f to force output)

Looking at other patches that add DSA support, they're fairly simple (could just be adding some lines to the .dts file) but how do I tell which switchport is used for the single ethernet? Most others with a single port seem to use port 5 ... I made a patch, it compiles, let's see if it works.

10

I think the dts file for the 3915 is a little different.
I found two relevant dts files in openwrt that might be of interest. There are more, but from older devices.
target/linux/mpc85xx/files/arch/powerpc/boot/dts/ws-ap3825i.dts
target/linux/ath79/dts/qca9557_extreme-networks_ws-ap3805i.dts

I think much more interesting is the dts file from an AP3935i. This device has two network interfaces.

The first network interface is configured there like this:

&gmac0 {
	status = "okay";

	qcom,id = <0>;
	mdiobus = <&mdio1>;

	pinctrl-0 = <&rgmii0_pins>;
	pinctrl-names = "default";

	phy-mode = "rgmii";
	phy-handle = <&phy1>;
	
	fixed-link {
		speed = <1000>;
		full-duplex;
	};
};
11

Ethernet works fine with this (as confirmation, netbooting shows eth4 has link):

sysupgrade went ok, but it doesn't automatically boot, it does when I enter the commands manually though. I briefly saw the openwrt SSID after enabling it in /etc/config/wireless, but with very low power, and then not since. The wireless LEDs are on, but they flash occasionally, nothing in dmesg though. I'm rebuilding with luci enabled in the image.

12

LUCI lets me see that the radios are listening at least, the wireless scan page works. AP power is still weird, when I can see the OpenWrt SSID, it was at -86dBm despite my phone being less than 5cm from the AP. Oh, now that I think about it, this AP in particular I removed from service because it was faulty. So that explains that. The boot issue was because I had newlines in the env vars, I redid them as a single line and it boots fine now.

Anyway I'll test again with a different AP on Monday and submit the patch to the mailing list if it works OK.

Hi trs80

Thanks for the patch

Do you have a short step by step Guide how to get the openwrt image on the AP?

15

The commit adding support has the instructions, but the short version is download both the image and sysupgrade files (you'll have to get the snapshot since it hasn't made a release), tftpboot the image, run sysupgrade and you're good to go.

16

Thx
I'm surprised.

Do I understand correctly that I have to compile the image myself with the hash e16a0e7e8876df0a92ec4779fe766de1a943307a?

Is the initramfs generated automatically when compiling?

The second option is to wait for the release.

When can we expect a release?

17

You can download snapshot builds of both from https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=ipq40xx%2Fgeneric&id=extreme-networks_ws-ap3915i

I don't know when the next release will be, apart from probably this year.

Hi,is the AP7632i-RW AP the same as AP3915i-ROW as far as hardware specifications are concerned? I have a few of the AP7632i-RW here and would like to flash openwrt onto it - if same hw flashing AP3915i-ROW should be working, shouldn't it?

19

There is the AP391x target but AP7632i-RW isn't listed, only AP7662, but given AP7632 is the same form as AP3915 it's worth a shot.

I gave it a try and successfully flashed a AP7632i with the latest stable 23.05.4 AP3915i firmware - followed the instructions and was quite easy going without any issues - thank you.

Just picked up 15 of these 7632i models for a very good price. How has your experience been with them? Hoping they will make good mesh nodes.
