Tracking down regression - LED CF-E538AC

For Developers
1

I have created a set of patches against 19.07.4 to add support for a Comfast CF-E538AC.
When testing I could not see any issues, all functions are available.

I then ported the patches to master and cannot find out why the LED (and reset button) do not work.

The DTS file is an exact copy, but in master I get this error that does not pop up in 19.07.4

[    4.602000] kmodloader: loading kernel modules from /etc/modules-boot.d/*

Also the LED device is not being created

19.7.04:
/sys/class/leds
cf-e538ac:white:wifi
mt76-phy0                rt2800soc-phy1::quality
rt2800soc-phy1::assoc    rt2800soc-phy1::radio

Master:
/sys/class/leds
mt76-phy0                rt2800soc-phy1::quality
rt2800soc-phy1::assoc    rt2800soc-phy1::radio

Please pay attention that pinctrl syntax was changed.
So this code in openwrt 19.07

&pinctrl {
	state_default: pinctrl0 {
		gpio {
			ralink,group = "uartf", "nd_sd", "wled";
			ralink,function = "gpio";
		};
	};
};

need to be changed to

&state_default {
	gpio {
		groups = "uartf", "nd_sd", "wled";
		function = "gpio";
	};
};

for current master branch.

@123serge123 Thank you so very much! I compared the dts file with others from master but never noticed that mine still was using ralink, group.
All good - now I just have to confirm that I didn't mess up anything else while testing and can submit the patches to hopefully add that device to openWRT

Hello,

I'm interested in support this device too (I saw your patch just before the device arrived to me). Let me know if I can help you with something.

BR,
ValentĂ­n

@vk496 - If you feel adventurous, you can try the firmware, BUT please ensure that you have serial access to recover the firmware via u-boot.

I selected a random sharing platform to upload test.bin (link expires in 30 days - around 20/12/2020):

Stock firmware available here:


Direct download link (it was only single digits kb/s coming from china):

Hello,

Thank you. I could flash the firmware trough OEM webinterface without problems (rebooted to OpenWrt with LUCI).

Here are all the things I could test:

  • LED works correctly. However, there are multiple options (mt76-phy0, rt2800soc-phy1::asoc, rt2800soc-phy1::quality, rt2800soc-phy1::radio, white:wifi). The last one is associated to the whit LED

  • Not all space is used (should be 8MB, no?). Problem with the mtd layout definition?

Filesystem                Size      Used Available Use% Mounted on
/dev/root                 3.0M      3.0M         0 100% /rom
tmpfs                    28.7M    236.0K     28.5M   1% /tmp
tmpfs                    28.7M     56.0K     28.7M   0% /tmp/root
tmpfs                   512.0K         0    512.0K   0% /dev
/dev/mtdblock6            2.9M    176.0K      2.7M   6% /overlay
overlayfs:/overlay        2.9M    176.0K      2.7M   6% /

And half of the RAM is used for /tmp. I supose is the default behaviour

  • The default VLAN config is in the reverse order. Port 2 should be untagged for WAN instead for LAN

And LAN interface is bridged with eth0. I think it should be with eth0.1

  • Wifi works corretly. 2ghz and 5ghz seems to be stable.

  • A dmesg during all the tests. For the case

Things I couldn't test:

  • Gigabit speeds. I only could try with Fast Ethernet.
  • The button

@vk496
Thank you for testing this. Could you please check if the MAC address matches the sticker on your box/the stickers that were provided with the device?

I think I found out why the overlay system is only has 2.9MB free space. Looking at this ( https://openwrt.org/docs/techref/flash.layout ) the 8MB are split as:
Root filesystem (3MB)
Kernel (5.2MB[firmware size] - 3MB[root] =~ 2.2MB) - not shown in df command
Overlay 2.9MB

LED - I have not found a way to disable the automatic creation of the LEDs by the module/driver [mt76 + rt2800]

I have now swapped wan/lan in the file "/etc/board.b/02_network" to make the PoE port LAN. I will upload that firmware soon, I just want to make sure that I haven't missed anything.

PS: I also only have a Fast Ethernet PoE switch.

I selected a random sharing platform to upload "test.bin" (default filename for u-boot recovery) (link expires in 30 days - around 23/12/2020):

Only change was to make back port (PoE port) LAN and front port as WAN

Hello,

Ok, make sense for the storage. The snapshots/official builds should be less heavy.

I confirm MAC address corresponds to the device label & box (Wifi mac differs in last digit). Also, RJ45 front port is gigabit capable, as expected to be.

2 days in production and no strange logs or wifi issues. Hope it could be merged in master soon :slight_smile:

Br,
ValentĂ­n :slight_smile:

10

Thanks for sharing the build!

Why are you interested in using the back port as LAN and the front one as WAN?

11

The device will only work while powered via PoE and I have now changed it so the configuration is possible with only one Ethernet cable connected.

12

So in that case, I can still use the WAN port (front port) to connect to my network, right? I am planning to use it as an AP, just like I have it now, but I would like the front port to be available.

Have you already tried Gigabit Ethernet?

I will probably flash your firmware this weekend.

13

Maybe we should avoid setting WAN at all?

I read suggestions from a OpenWrt Telegram Group (some maintainers there) that for a specific case like this device (mainly for AP repetear/extender), using LAN for both ports would be fine.

Maybe just using a non default IP range (like 192.168.255.0/24) to avoid IP overlapping when it's connected to a OpenWrt with default LAN config...

Br,
ValentĂ­n :slight_smile:

14

Update: I flashed the firmware and apparently the Wireless emitters and the WAN (front) port seem to be capable of supporting Gigabit networks. However, the LAN port is limited to Fast ethernet, and it is bottlenecking the whole network.

ÂżAny ideas about how can I solve this? I can provide logs if they can help.

15

I have checked the configuration and so far cannot see anything that might be different between the front and back network connection.

Both use the same model Transceiver chip and both are connected to the two Gigabit ports of the internal switch of the SoC chip using the same protocol. I am not sure where that bug might come from.

Unfortunately, I cannot test it with my device since I only have a FastEthernet PoE switch available.

16

That is strange. I will try another cable as suggested in another post just to discard that problem...

17

Hello,

@polystera could you please share your last patch? I don't see your patch support in master branch and would really like to have this device officially supported.

Br,
ValentĂ­n

18

Btw, I bought a Gigabit POE inyector, but the device still report 100mbit over PoE. I hope this weekend I'll have time to inspect the issue.

Br,
ValentĂ­n

Hi ValentĂ­n,

I have tried to submit my patch set, but it still needs work. I was asked for a boot log, but just destroyed my device on that day. I only had a boot log from my patch against 19.07.
I have ordered a new device. Delivery from China... maybe end of January?

The latest I have done is to create the device page (I noticed that I haven't linked it yet in the table of hardware in the wiki - if you have time please fix that :slight_smile: )

I will still have to ask a couple of questions regarding some DTS settings and the wan/lan setup the devs would like to see in my patch.

20

Done, devicepage added to dataentry.
