Other Parts Discussed in Thread: WL1271
Tool/software: Linux
I'm trying to integrate the wifi module WL1271L with am335x using TI processor SDK with its kernel version processor-sdk-linux-04.00.00
It appears to me that the required driver and firmware are already installed by TI SDK on the rootfs and I only have to configure the DTB, right?
I have configured the DTB as the following:
&mmc2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&mmc2_wifi_pins_default>;
vmmc-supply = <&vmmc_reg>;
bus-width = <4>;
max-frequency = <25000000>;
ti,needs-special-hs-handling;
cap-power-off-card;
keep-power-in-suspend;
#address-cells = <1>;
#size-cells = <0>;
wlcore: wlcore@0 {
status = "okay";
compatible = "ti,wl1271";
reg = <1>;
interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
};
};
But when I try to enable the wifi module, I got the following error from kernel (dynamic debug is enabled on some module):
[ 163.275106] omap_hsmmc 481d8000.mmc: card claims to support voltages below defined range

In wlcore_probe_of probe function, of_match_node return null and doesn't much any device.
Any Help?
Thanks,
