Comment (by mikebrady@…):
So, I redid the experiment and it seems to confirm the breakage at r41441.
Maybe I'm doing something stupid – it wouldn't be the first time... I
believe it shows that the breakage occurs between r41440 and r41441 on a
standard build of OpenWrt for a Raspberry Pi (Model B FWIW) adding what I
think is the minimum to the build to be able to drive the RT5370 and
associate with a WPA Personal network. This post is a bit long, BTW:
Get trunk and go back to r41440:
{{{
git clone git://git.openwrt.org/openwrt.git rpi
cd rpi
# go back to r41440
git checkout 0f766540674b26a82d14310da237aa86e777109b
./scripts/feeds update -a
make menuconfig
#Target System > Broadcom BCM2708/BCM2835
#Kernel modules > Wireless Drivers > kmod-rt2800-usb
#Network > wpa-supplicant
}}}
Here is the diffconfig:

Build and install.
Edit the wireless configuration so that it looks like this:
{{{
root@OpenWrt:/# cat /etc/config/wireless
config wifi-device radio0
option type mac80211
option channel 11
option hwmode 11g
option path 'platform/bcm2708_usb/usb1/1-1/1-1.2/1-1.2:1.0'
option htmode HT20
config wifi-iface
option device radio0
option network wlan
option mode sta
option ssid '<<My Network>>'
option encryption psk2+aes
option key '<<My Password>>'
}}}
Reload the wifi configuration:
{{{
wifi reload
}}}
At this point, the RA5370 associates with the network (a little blue LED
lights up). Running ifconfig:
{{{

After editing /etc/config/network to read:
{{{

ifconfig reads as follows:
{{{

So, IMHO, everything is in order.
Now,moving to r41441...
{{{
git checkout master
git checkout bfbbb266bb4b37eae02d565b8a66fac28344c3a4
make clean
make menuconfig
}}}
Here is the diffconfig, which is the same as before, I think:
{{{
mike@ubuntu:~/openwrt/rpi$ ./scripts/diffconfig.sh
CONFIG_TARGET_brcm2708=y
CONFIG_TARGET_brcm2708_RaspberryPi=y
CONFIG_TARGET_BOARD="brcm2708"
CONFIG_DRIVER_11N_SUPPORT=y
CONFIG_PACKAGE_MAC80211_DEBUGFS=y
CONFIG_PACKAGE_MAC80211_MESH=y
CONFIG_PACKAGE_hostapd-common=y
CONFIG_PACKAGE_iw=y
CONFIG_PACKAGE_kmod-cfg80211=y
CONFIG_PACKAGE_kmod-crypto-aes=y
CONFIG_PACKAGE_kmod-crypto-arc4=y
CONFIG_PACKAGE_kmod-crypto-core=y
CONFIG_PACKAGE_kmod-lib-crc-itu-t=y
CONFIG_PACKAGE_kmod-mac80211=y
CONFIG_PACKAGE_kmod-rt2800-lib=y
CONFIG_PACKAGE_kmod-rt2800-usb=y
CONFIG_PACKAGE_kmod-rt2x00-lib=y
CONFIG_PACKAGE_kmod-rt2x00-usb=y
CONFIG_PACKAGE_wpa-supplicant=y
CONFIG_WPA_SUPPLICANT_INTERNAL=y
mike@ubuntu:~/openwrt/rpi$
}}}
Using the same /etc/config/wireless, when the wifi configuration is
loaded:
{{{
wifi reload
<<nothing seems to happen >>
}}}
Sure enough, ifconfig reads:
{{{
root@OpenWrt:/# ifconfig -a
eth0 Link encap:Ethernet HWaddr B8:27:EB:FF:9F:74
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

RX bytes:41478 (40.5 KiB) TX bytes:47585 (46.4 KiB)
lo Link encap:Local Loopback

RX bytes:97920 (95.6 KiB) TX bytes:97920 (95.6 KiB)
}}}
In conclusion, this is completely repeatable. To answer a previous
question, if I build an up-to-date trunk (as of last night – can't
remember the rev number) but revert r41441 and r41442, the RA5370 works as
expected.
