各位好
目前要將marvell 8686加到BF527-ezkit上，使用的是spi介面，由koop上找到使用SDIO的方式，也找到一個網站如下：
wireless.kernel.org/en/users/Drivers/libertas
網站上有說明如何加上 Marvell GSPI，但是在source code內找不到libertas_spi.h，不知該如何去新增?
我使用的uclinux image為 uClinux-dist-2009R1.1-RC4。

Gordon,
You need to use SVN trunk kernel - I can see "linux-kernel/include/linux/spi/libertas_spi.h" on svn trunk.

您好，我要到那去下載 SVN truck kernel ?
因為是初學者，所以有很多知識還不懂，還請您多多指導~
謝謝

Hi Yi Li
I use "svn" to download the source code. and compiler it. Now I can get the libertas_spi.ko,
but when I use the module, I can't get WiFi module, I run the command below
root:>modprobe libertas
root:>modprobe libertas_spi
but nothing happen, I can't find my wifi interface by "iwconfig"
Can you teach me what file do I need to modify?

Did you install the libertas firmware to roofs?
Please refer to https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:wifi_over_sdio&s[]=libertas

Hi Sonic
I put the bin file gspi8686.bin and gspi_hlp.bin to rofms/lib/firmware and romfs/lib/firmware/libertas.

We don't have gspi8686.bin and gspi_hlp.bin. So, we have never tested it.

Hi Sonic
Do you ever implement the libertas_spi for Marvell 8686 ?
Do you have me to test the librertas_spi ? I can send the bin files to you ?

We don't have the marvell 8686 SPI hardware either. So, we haven't implemented and tested this driver.

Gordon,
We don't have the 8686-spi hardware to test.
Maybe you did not load the firmware correctly? see: docs.blackfin.uclinux.org/doku.php?id=linux-kernel:hotplug#firmware

Hi all
I modify the file ezkit.c at linux-2.6.x/arch/blackfin/mach-bf527/board/, I add below :
static int spi1_libertas_setup(struct spi_device *spi)
{
spi->bits_per_word = 16;
spi_setup(spi);
return 0;
}
static struct libertas_spi_platform_data libertas_spi_platform_data_info =
{
.use_dummy_writes = 0,
.setup = spi1_libertas_setup,
};
static struct spi_board_info bfin_spi_board_info[] __initdata = {
{
.modalias = "libertas_spi",
.max_speed_hz = 45000000,
.bus_num = 0,
.chip_select = 3,
.platform_data = &libertas_spi_platform_data_info,
.mode = SPI_MODE_0,
},
}
and
#include <linux/spi/libertas_spi.h>
and
I use the bf527-ezkit to test it.
Now I can get two error message when I run the driver,
root:/>modprobe libertas
root:/>modprobe libertas_spi
libertas_spi : Libertas SPI driver
libertas : Can't read bus mode register.
libertas_spi : probe of spi0.2 failed with error -5
1. How do I set the demo board switch ?
2. How do I can read bus mode register?
3. The error -5, How do I to fix?
Thank you!
Gordon

Hi Yi
I had been setting the firmware load support.
