Hello, <br>
<br>
First I would like to thank you guys for your AR6001 patches, very
helpful. I'm trying to get this chip to work over SDIO on a
at91sam9260 dev board and was wondering if I could talk you gentlemen
into a little assistance. <br>
<br>
I took a vanilla 2.6.24 kernel, applied the at91 patches and then
applied the patches (minus the gta02 patch) found at:<br>
<a class="moz-txt-link-freetext" href="http://svn.openmoko.org/developers/sameo/patches/ar6k-atheros-2.0/2.6.24/">http://svn.openmoko.org/developers/sameo/patches/ar6k-atheros-2.0/2.6.24/</a><br>
<br>
Here are some of the .config entries. I tried to the match the
relevant parts to the defconfig at:<br>

The kernel compiles mostly cleanly (a few warnings). When I boot a
open-embedded minimal image and take a look at dmesg, this is what I
get (having MMC debug enabled):<br>

I don't think it's in there?? I do have an entry in sysfs
(sys/class/mmc_host/mmc0....)<br>
A regular SD flash card works just fine on the board, but AR6k wifi
cards obviously do not. <br>
<br>
Does anyone have an idea what is wrong with my current setup? <br>
<br>
Thanks!<br>
