In order to get it to work on a different board, you'll need to set up the script.bin to enable the mmc port it's attached to. On the CT, the chip is hooked up to mmc3, so its script.fex looks like this: [mmc3_para] sdc_used = 1 sdc_detmode = 4 sdc_buswidth = 4 sdc_cmd = port:PI04<2><1><2> sdc_clk = port:PI05<2><1><2> sdc_d0 = port:PI06<2><1><2> sdc_d1 = port:PI07<2><1><2> sdc_d2 = port:PI08<2><1><2> sdc_d3 = port:PI09<2><1><2> sdc_det = sdc_use_wp = 0 sdc_wp = sdc_isio = 1 sdc_regulator = "none" You'll also need to specify the gpio that's used for enabling it.

allwinner gpios to turn on the chip. Cubietech made some changes for that
to drivers/net/wireless/bcmdhd/dhd_custom_gpio.c, which is meant by
Broadcom to be customized to different boards (thus the "custom" in the
name). It could all be abstracted pretty easily in the 3.4 linux-sunxi
kernel, except for a few new calls to sunximmc_rescan_card made after power
off and power on (probably not needed after the power off).
The mainline kernel abstracts this stuff much better than 3.4, so
backporting might not be so easy.

Re: [linux-sunxi] Re: How to test wifi in A20.
Hi Puneet,
bcmdhd is currently not working in the sunxi-3.4 kernel; this is known.
We will try to backport the 3.14 patches to see if that makes it work.
The cubieboard kernel's patched some stuff in but I think there's a bug
somewhere as you mention with the gpio's. I did see this document
somewhere (mailing list or some wiki; i forgot)

Hi,
While tracing problem i found below issue.
i am getting error in log as:

Which means some gpio error:

ap6xxx_lpo = port:PI12<4>
For ap6xxx_wl_host_wake , i check by making high and low but error is same.
Can any one tell why that error is, Is it because of some gpio pins or
something else went wrong?
