wifi over SDIO

[olimexman]

Hi,
We're doing a breakout board with wifi over SDIO, using the pins available through the expansion header. I'am confused about "script.fex" because it have a "[wifi_para]" section rather than "[sdio_wifi_para]", how should i change it in my case?
Thank's in advance
Daniel

These are equivalent. Just use the "[wifi_para]" section.

Edit: word

Hi LubOlimex

Thank's for the response ... and sorry for too late resume ...

We have made the following changes to the script.bin:

[wifi_para]
wifi_used = 0 -> 1
wifi_sdc_id = 3
wifi_usbc_id = 2
wifi_usbc_type = 1
wifi_mod_sel = 3 -> 10
wifi_power = ""

Value for wifi_mod_sel based on this url: http://linux-sunxi.org/Fex_Guide
"10    rtl8189es    RTL8189ES(SM89E00)"

Trying ...

root@A20-OLinuXino:~# modprobe 8189es
modprobe: ERROR: could not insert '8189es': Operation not permitted

dmesg ...

[ 3475.188494] [mmc_pm]: No sdio card, please check your config !!
[ 3475.199194] [rtl8189es] rtw_drv_entry: mod_sel = 0 is incorrect.

Why could be the reason to claim "mod_sel = 0" ... no matter what value we set to wifi_mod_sel it always claim about mod_sel = 0 is incorrect ... could it be hard coded within the module?

Any clues are welcome ... we are locked with this

Thank's in advance

RTL8189ES has own driver: http://linux-sunxi.org/Wifi#RTL8189ES_.2F_RTL8189ETV

Hi LubOlimex,

Thank's for your responses ... we are currently using the legacy kernel rather than the mainline one ... the suggested driver won't compile using the legacy kernel as we discover ... probably because is designed for other kernel version superior (mainline kernel)

Then we have tried the last source code at this url "http://linux-sunxi.org/Wifi#8188eu_driver_on_sunxi-3.4" ... which must function on legacy kernel ... "https://github.com/LazyZhu/myblog/raw/gh-pages/file/RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip"

It compile without errors and load with modprobe
root@A20-OLinuXino:~# lsmod
Module                  Size  Used by
disp_ump                 869  0
mali_drm                2616  1
drm                   207727  2 mali_drm
8189es                732194  0 <-------------------------------------<<
ftdi_sio               33939  0
...

But it won't work and not wlan0 interface exist

Then we search sdio bus status and found the following:

root@A20-OLinuXino:~# ls /sys/bus/sdio/devices/
It does not appear

root@A20-OLinuXino:~# ls /sys/bus/sdio/drivers
rtl8189es

In dmesg extract ... we could see this

We are researching ... there is not firmware specific for 8189es as long as we see ...

Thank's in advance
