How to porting AP6210 wifi + bt device?

fulinux — Thu, 02 Jun 2016 04:37:44 GMT

Hi community,

my board is imx6, and i am porting BSP which version is imx_4.1.15_1.0.0_ga . i am a new hand. our custom board was made by another company, we have no schematic circuit diagram of the board. but we have a running well kernel (version: linux-3.0). i am porting my new BSP refer to the old kernel. some modules porting have successed. i am poring wifi module on my board, it is model is ap6210, i have never porting a wifi module, and porting it on device tree file. i don't know what should i do? have you porting ap2610 wifi module?

there are my old kernel machine board files attached. waiting for your feedback.

thank you,

fulinux.

Hi fulinux

seems ap6210 is supported in mainline kernel

AP6210 - Linux Rockchip

regarding porting guidelines one can apply to vendor of

that device.

Best regards

igor

Hi igor,

thank you, but i want to know how to add dts node of ap6210 for fsl BSP.

i found this:

linux-3.0:

arch/arm/mach-mx6/board-mx6q_sabresd_piano.h

static iomux_v3_cfg_t mx6q_sabresd_pads[] = {

......

/*WIFI_HOST_WAKE*/

MX6Q_PAD_CSI0_DAT18__GPIO_6_4,

......

};

arch/arm/mach-mx6/board-mx6q_sabresd_piano.c:

#define WIFI_HOST_WAKE IMX_GPIO_NR(6, 4)

....

int bcm_wlan_get_oob_irq(void)

{

int host_oob_irq = 0;

gpio_request(WIFI_HOST_WAKE, "wifi_host_wake");

gpio_direction_input(WIFI_HOST_WAKE);

host_oob_irq = gpio_to_irq(WIFI_HOST_WAKE);

printk("host_oob_irq: %d \r\n", host_oob_irq);

return host_oob_irq;

}

EXPORT_SYMBOL(bcm_wlan_get_oob_irq);

but in linux-4.1 i found WIFI_HOST_WAKE defined to GPIO1_IO27 in iomuxc dts node:

&iomuxc {

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_hog>;

imx6qdl-sabresd {

pinctrl_hog: hoggrp {

fsl,pins = <

....

MX6QDL_PAD_ENET_RXD0__GPIO1_IO27 0x80000000 /* WL_HOST_WAKE */

....

};

how can i defined WIFI_HOST_WAKE pin to gpio6_IO4, and where place to use WIFI_HOST_WAKE pin in linux-4.1?

if i write like this:

imx6qdl-sabresd {

pinctrl_hog: hoggrp {

fsl,pins = <

....

MX6QDL_PAD_CSI0_DAT18__GPIO6_IO04 0x80000000

....

};

should i modify code in kernel to use gpio6_io4 ? and where palce?

ap6210 uses BCM43362 / BCM20710 and one can look at

BCM4339 example in attached Linux Manual sect.46.3 Device Tree Binding

Hi igor,

thank you for you replay, it has not mention WL_HOST_WAKE irq pin, how should i add host wake pin define and use the pin?

refer to imx6qdl-sabresd-btwifi.dtsi.

thank you very mach.

I also have encountered this problem on my board with imx_4.1.15 kernel.I used the kernel's own bcmdhd and I have copy the bin and vnram.txt from linux-sunxi-ap6210/firmware/ap6210 at sunxi-3.4 · armStrapTools/linux-sunxi-ap6210 · GitHub

现在系统起来后，ifconfig能够找到wlan0，但是我不太确定这个wlan0是不是能够正常工作。因为我用ifconfig设置静态IP后，然后将udhcpd打开,udhcpd.conf中已经设置了wlan0和地址池，然后启动hostapd，我已经解决了启动hostapd时的random和RFKill的错误。然后手机能够搜索到wifi模块的SSID，但是手机输入hostapd中设置好的密码，结果却连接不上。

这是手机连接wifi后的信息：
