WandboardQuad WIFI REV D1 - Recent kernel?

[sniffer]

Anybody got wifi working on the Rev 1d quad with debian on a recent kernel? I purchased two replacement boards for two dead C1 boards and received D1 boards and now wifi will not work.

The C1 boards were running using Robert Nelson's recipe at https://eewiki.net/display/linuxonarm/Wandboard but now, with the 4339 firmware installed, and a Rev D1 dtb, I get "brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50" and no wifi device.

Anybody any clues?

Cheers,
Mike.
