Real6410 Android 2.1 sdio WiFi

1. Download the firmware from here

Http://extranet.marvell.com/drivers/driverDisplay.do? Driverid = 203.

26409. The p45-GPL is for Linux core 2.6

Parse it and you will find two files: helper_sd.bin and sd8686.bin.

Rename helper_sd.bin to sd8686_helper.bin (do not ask why it is different)

2. You have two options to use sd8686 wifi. You can put sd8686_helper.bin and sd8686.bin into the core or file system.

This is the internal core mode or mode. For me, I put it in the inner core because I still have the NAND space as zimage.

# Make xconfig

Device Drivers --->
Generic Driver options --->
() External firmware blobs to build into the kernel binary
() Firmware blobs root directory

Set "external firmware blobs" = "sd8686_helper.bin sd8686.bin"
Set "firmware blobs root directory" = "firmware"
Put these sd8686_helper.bin and sd8686.bin in firmware

This is the. config configuration file. For more configurations, see the hands of real6410 Android 2.0? V1.2.

Now you can create an internal core.

# Make-J2 SDK

3. Android uses a modified wpa_supplicant for WiFi support. You need to use wpa_supplicant. To open boardconfig. ml and add a line of proxy:

Board_wpa_supplicant_driver: = wext

4. You can use DEBUG to view more information for wpa_supplicant.
Change wpa_debug_level = msg_debug in external/wpa_supplicant/common. C.
Change external/wpa_supplicant/common. h to... If (level)> = msg_info) to If (level)> = msg_debug)

5. Create the configuration file/Android-2.1/system/CORE/rootdir/etc/WiFi/wpa_supplicant.conf. It will redirect to/system/etc/WiFi/wpa_supplicant.conf.

Ctrl_interface = eth1
Update_config = 1

6. Add a router interface, permission control and service init. RC (if the permission restriction is problematic, change it by yourself)

Chmod 0770/system/etc/WiFi

7. This is because I need to disable insmod () and rmmod () in the internal kernel mode, because the android UI will be used to enable WiFi and disable Wi-Fi:
/Libhardware_legacy/WiFi/wifi. c
....
Static int insmod (const char * filename, const char * ARGs)
{
/* For Kernel Mode WiFi */
Return 0;
Void * module;
Unsigned int size;
Int ret;
Module = load_file (filename, & size );
If (! Module)
Return-1;

Ret = init_module (module, size, argS );
.....
.....
Static int rmmod (const char * modname)
{
/* For Kernel Mode */
Return 0;

Int ret =-1;
Int maxtry = 10;
.....
....
8. If you want to manually perform failover, these two commands can help you. Use strace to see if wpa_supplicant has or does not have any problems.
# Strace/system/bin/wpa_supplicant-dd-dwext-ieth1-C/system/etc/WiFi/wpa_supplicant.conf
If you have no questions, you can:
#/System/bin/wpa_supplicant-dd-dwext-ieth1-C/system/etc/WiFi/wpa_supplicant.conf &
This interactive command:
/System/bin/wpa_cli-I eth1-P/data/system/wpa_supplicant
