Hi folks,
I am trying to get mainline Linux running on my Wink Hub v1 (imx28 with
Broadcom 4334 via SDIO). I am using the nvram.conf that the vendor shipped
with back in 2014, and brcmfmac driver.
I experienced the below panics at some point during the night, printed to
the serial console. The device was idle, but obviously receiving broadcast
traffic from the rest of the network. This is a near mainline kernel,
running an OpenWrt mainline userland. The interface is configured as a
station to my AP.
# iw dev phy0-sta0 info
Interface phy0-sta0
ifindex 2
wdev 0x1
addr 34:23:ba:eb:14:5f
ssid Dawes
type managed
wiphy 0
channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz
txpower 31.00 dBm
#
I know absolutely nothing about WiFi drivers, so would need to be walked
through collecting any information that will help to fix this.
# iw dev phy0-sta0 info
Interface phy0-sta0

channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz
txpower 31.00 dBm
FWIW, the performance of the WiFi interface is pretty poor. It seems to
hang periodically, and when it is running, the best throughput I get is
around 1.4MB/s copying an unpacked tarball from a local computer to
/dev/null over wifi. This does seem to be a problem with the vendor kernel
as well, as I have seen comments to the effect of "Poke the wifi interface
to keep it awake" while reviewing their firmware update scripts! FWIW, the
vendor firmware constrains the radio to only connect to 2.4GHz AP's, even
though it is apparently 5GHz capable too.
Please let me know if I can provide any more information.
Regards,
Rogan
