Hi,
I have wifi working on cubietruck, but after several minutes of operation
it stops work. The kernel was compiled from the latest sunxi-devel branch
of linux-sunxi repo.
Ifconfig says that wlan1 is running, but all operation fails by timeout.
# iwlist wlan1 scan
wlan1 Interface doesn't support scanning : Connection timed out
# time iwconfig wlan1
wlan1 IEEE 802.11bgn ESSID:off/any

Each second two messages appears in dmesg:
brcmfmac: brcmf_sdiod_regrw_helper: failed to read data F1@0x0a020, err:
-110
brcmfmac: brcmf_sdio_dpc: failed backplane access over SDIO, halting
operation
More related messages:

brcmfmac: brcmf_cfg80211_scan: scan error (-110)
The command rmmod brcmfmac never finishes.
Also, when wifi stops work, mmc error messages repeat in dmesg:
[ 245.780430] sunxi-mmc 1c12000.mmc: smc 1 err, cmd 53, RD SBE !!
Right, this is the infamous SBE error, a known issue, for which I've been
unable to find a fix. Any help with fixing this is very much welcome.
After the first SBE error any commands reading data from the device
will fail with a DTO error. But it is the first SBE error which seems
to kill things. I've reviewed the sunxi-mmc code countless times and tried
various approaches (such as resetting the entire mmc controller) to work
around this, but all without success.
Does Broadcom know what this is, or do they have a better way to debug it?
Where can I find the linux-sunxi repo? github?

When wifi module is unloaded there are not any mmc errors.
I use dd if=/dev/zero bs=64k command via ssh to test wifi.
I can also check other versions of kernel.
Best,

Those are "normal" this is the brcmfmac driver trying to enable some
features which are not supported on this model wifi chip.
