Hi all
I am running a custom build of Openwrt x86_64 EFI on a z83ii which is an Atom based miniPC.
This device has an internal eMMC and AP6255 WiFi which are detected ok, if I enable the ACPI SDIO support in kernel.
But this device has also a SDIO slot, which seems that does not work. If I plug a SD card in it, it is not detected.
What can be the problem? Peraphs it is required some user space action upon SD plugin?
Bye
checked lsusb ?
You probably need to load some additional modules.
It is not a USB based SDIO adapter. It is an internal PCIe one
so lspci then 
This is what I get, which is somehow strange:

I mean, apparently there is no SDHCI controller but:
root@MenionRouter:~# cd /sys/class/mmc_host/
root@MenionRouter:/sys/class/mmc_host# ls
mmc0 mmc1
root@MenionRouter:/sys/class/mmc_host#
Where mmc0 is the eMMC, and mmc1 is the broadcom AP6225
once booted, put a SD card in, and then run dmesg.
SD cards usually pop up as regular drives /dev/sdX, via the scsi driver.
There is no activity in dmesg.
Also the mmc pop us as /dev/sdX only if the MMC adaptor is USB. For the real SDHCI adapter you get mmcblkx device.
It was working perfectly in UBuntu. In openwrt the SDHCI subsystem is disable by default for some reason in x86 build (need to enable it in kernel_menuconfig), but the result is partial, since as said, only eMMC and WiFi pop up
It's not PCIe.
It must be SDIO coming out of the SoC or something. It's a newer Atom.
Try checking dmesg in Ubuntu and seeing if you can identify when udev sets the device up.
Hi, may i have the firmware? I have the device and want to try it.
Hello all, can anyone help how to enabled the wifi AP6255 on z83ii ? Thanks you
dmesg and lspci would probably help.
hello frollic, thanks for fast replay. this is my result dmesg and lspci.

is this correct brcmfmac 43340? do you have any further instructions or tutorials?
thanks you
Do you have the matching firmware package installed?
last night i try to build x86_64 from ROOter, and i try to add bcmfmac package, but im forgot about detail. and now i got trouble on my ssd to using ubuntu.
do you mean this package?

For R00ter, I have no idea.
do you have any other ideas? can you share the method you use to turn on the wifi? or firmware compatible with this device.
