Other Parts Discussed in Thread: AM3358, WL1835
hello,
we have interface wl1835 wifi chip with out am3358 based custom board and ping google successfully.
now i am interfacing Bluetooth on UART 5
i am following 
i have configure UART 5 something like
uart5_pins: uart5_pins {
pinctrl-single,pins = <
AM33XX_IOPAD(0x908, PIN_INPUT_PULLUP | MUX_MODE3) /* (H16) gmii1_col.uart5_rxd */
AM33XX_IOPAD(0x944, PIN_OUTPUT_PULLDOWN | MUX_MODE3) /* (H18) rmii1_refclk.uart5_txd */
AM33XX_IOPAD(0x90c, PIN_INPUT | MUX_MODE5) /* (H17) gmii1_crs.uart5_ctsn */
AM33XX_IOPAD(0x910, PIN_OUTPUT_PULLDOWN | MUX_MODE5) /* (J15) gmii1_rxer.uart5_rtsn */
>;
};
&uart5 {
pinctrl-names = "default";
pinctrl-0 = <&uart5_pins>;
uart-has-rtscts; //fsl,uart-has-rtscts;
status = "okay";
bluetooth {
compatible = "ti,wl1835-st","ti,wl1835";
// enable-gpios = <&gpio2 2 GPIO_ACTIVE_HIGH>;
};
in dtsi file i have changed
uart5: serial@481aa000 {
compatible = "ti,am3352-uart", "ti,omap3-uart";
ti,hwmods = "uart6";
clock-frequency = <48000000>;
reg = <0x481aa000 0x2000>;
interrupts = <46>;
status = "okay";
dmas = <&edma 3 1>, <&edma 4 1>;
dma-names = "tx", "rx", "rts", "cts";
};
i am getting bluetooth communication log at board boot time
