Chipset RTL8188CUS

I will give you the detail for the RTL8188CUS driver error I got for AFP28 with AFP28devdev.

1)I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .

You can get the driver here (chose RTL8188CUS) : [1]

Add those option in the makefile :

- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 :
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := arm-linux-
KVER  := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif

2)Here is the test I made :

modprobe 8192cu
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0

Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

Then I try to connect with SFTP from my PC (using FileZilla) :

the wifi goes down and the usb with it.

3)Here is the part of "messages" where the error is :
