Other Parts Discussed in Thread: WL1835
Hello all,
I am trying to bring up the the WL1835 module on our custom board which is running on i-MX6 solo processor. I followed the below documents:
1)WiLink8 Linux Getting Started Guide
2)WL18xx Platform Integration Guide
3)WL18xx First Time Getting Started Guide (IMX6)
By following all these documents I generated the modules,wl18xx-fw-4.bin,related libraries ,bt-firmware etc.
I modified the below files:
t_kim.c, st_ll.c, ti_wilink_st.h, tty_hci.c ,Kconfig, Makefile,imx_v7_defconfig and btwilink.c. in the kernel.
I modified my dtsi file as follows:
wlan_en_reg: fixedregulator@2 {
compatible = "regulator-fixed";
regulator-name = "wlan-en-regulator";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
/* WLAN_EN GPIO for this board - Bank5, pin2 */
gpio = <&gpio5 2 0>;
enable-active-high;
};
kim {
compatible = "kim";
nshutdown_gpio = <80>; // GPIO3_16 The wl8 driver expects gpio to be an integer, so gpio3_16 is (3-1)*32+16=80
dev_name = "/dev/ttymxc1";
flow_cntrl = <1>;
baud_rate = <3000000>;
};
btwilink {
compatible = "btwilink";
};
pinctrl_uart2: uart2grp {
fsl,pins = <

};
pinctrl_usdhc2: usdhc2grp {

&uart2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart2>;

&usdhc2 {

cap-power-off-card;

wlcore: wlcore@0 {
compatible = "ti,wl1835";
reg = <2>;
interrupt-parent = <&gpio4>;
interrupts = <8 IRQ_TYPE_EDGE_RISING>;
};
};
Now when I am trying to load the modules I am getting below errors:

So my question am I missing some files?
Do I need more modifications in Rootfs?
Is there any mismatch in version?
