Package: firmware-brcm80211
Version: 20160110-1
Severity: normal

On an Asus X205T, dmesg says:

brcmfmac_sdio mmc1:0001:1: firmware: direct-loading firmware brcm/brcmfmac43340-sdio.bin
brcmfmac_sdio mmc1:0001:1: firmware: failed to load brcm/brcmfmac43340-sdio.txt (-2)
brcmfmac_sdio mmc1:0001:1: firmware: Direct firmware load for brcm/brcmfmac43340-sdio.txt failed with error -2
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50

and no network interface appears for the device.

It looks to me like the brcmfmac_sdio kernel module is expecting this
.txt file is supposed to be shipped alongside the .bin, but it isn't
present.

        --dkg

hm, https://wiki.debian.org/InstallingDebianOn/Asus/X205TA#WiFi
suggests:

   cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt

and indeed, after doing that, and then removing and re-loading the
kernel module with:

 modprobe -v -r brcmfmac
 modprobe -v brcmfmac

then the device is found correctly.

     --dkg
