I am not seeing any errors in "dmesg" or "logread", but the wifi is not working on OpenWRT. @kraj Could you please let me know, what are all the configurations required to bring up the wifi on OpenWRT.

[danielfdickinson]

Are you including netifd and using it or are you using hostapd directly?

What processes are running?

How are you trying to bring up the wireless? This layer is relatively experimental, so things like wireless may not 'automagically' work. Part of that may be because regular OpenWrt uses a modified wireless-next tree, hostapd, etc (though thing should still mostly work AIUI).

Is your wireless supported on OE without OpenWrt? I seem to recall some discussion around the Pi 3 wireless module support.

Daniel

if you use latest master meta-raspberrypi layer it uses right firmware blobs to bringup on-board wifi I have not tried to bring up wifi on pi3 myself with openwrt layer but it works fine with OE in general

@cshoredaniel , I am replying on behalf of Satish Naidu, we work together. We are including netifd and using it.
when we try apply the wifi config and try bringing up wlan0 is shown up in ifconfig -a but wlan0 link is not ready. Please suggest how to get it work on yocto with openwrt layer.

Ah, I though you were doing AP mode. Do you have wpa_supplicant? (I'm not sure if that's enough or if a recipe doing OpenWRT-like multi-call wapd is necessary for client mode).

Does the client attempt to make a connection but fail (i.e. when you watch wireless traffic)? Do you have busybox's udhcpcd included? (netifd doesn't grok dhcp-client from ISC).

Hi @cshoredaniel ,

Please find the below observations: Do you have wpa_supplicant? we are not using any wpa_supplicant file explicitly in the conf/local.conf file. OpenWRT-like multi-call wapd is necessary for client mode: I tried to include wpad in OpenWRT through Yocto, but there is no recipe available. ( I assume we don't need this module, because we are not doing anything complex just simple wifi client)

Does the client attempt to make a connection but fail : In the logread we are not seeing any errors, the connection itself is not established so not getting any errors. the netifd is not eveing loading the wan interface when we specify ifname as wlan0.

But when we configure ifname as eth0 instead of wlan0 in , /etc/config/network

config interface 'wan' option ifname 'eth0' option proto 'dhcp'

In the logread, netifd is trying to loading the wan interface but not getting any ip address.

You need at least one of wpa_supplicant or wpad to do wireless with netifd.

If you don't have a wired connection then that is understandable. This should, however, work with a wired connection.

With netifd eth0 will be associated with the physical ethernet port.

Hi @cshoredaniel,

As per your suggestion, I have added wpa_supplicant in local.conf file able to bring up the wifi on OpenWRT. The steps I have followed is as follows:

1. ifconfig wlan0 up
2. wpa_passphrase 'SSID' 'Password' > /etc/wpa_supplicant.conf
3. wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
4. dhclient wlan0 or
5. iwconfig wlan0 'SSID' ( For WEP encryption)
6. dhclient wlan0

Now my question is, if we configure the wifi details through wpa_supplicant file, what is the purpose of /etc/config/wireless file. If we want to change the wifi details through "uci command", is there a way to update this wpa_supplicant file?

[danielfdickinson]

There should be a script that netifid uses to bring up client wifi 'automagically'. If that script was missed (i.e. in the netifd or wpa_supplicant 'tweak' recipe), that could explain why netifd isn't bringing the wifi. I'm thinking client mode may not have been included in the work on meta-openwrt so far (in terms of making sure all the needed openwrtisms are present).

[iuncuim]

@cshoredaniel @kraj I think that iwinfo with this bb don't include nl80211 API. Maybe this is the problem?

[danielfdickinson]

@iuncuim that would make sense...best thing to do is look at https://git.openwrt.org/openwrt/openwrt.git I guess.

As far as I understood, the issue comes from brcmfmac. Every time you restart hostapd using UCI, it grabs HT capabilities from iw list, which in turn gets it from the driver. If you set up 80211n=0 (so basically Legacy mode) it will work, because HT is then disabled. Driver reports SHORT-GI-HT40 is supported, but it can't bring up the interface with this option, because it requires falling back to mimo_bw_cap, but driver doesn't do it (patch available in the open). Using wl binary from cypress website and setting mimo_bw_cap manually helps. I am looking on the ways how it can be fixed now.
