Hi, i'm using 66AK2G02 (K2G) Evaluation Module. And i will setting McBSP interface to receive data from same ADC.

First step configure McBSP pins

	mcbsp_pins: pinmux_mcbsp_pins {
		pinctrl-single,pins = <
			K2G_CORE_IOPAD(0x135c) (BUFFER_CLASS_B | PIN_PULLDOWN | MUX_MODE2) 	/* PR1_PRU1_GPO14.MCBSP_CLKR */
			K2G_CORE_IOPAD(0x1354) (BUFFER_CLASS_B | PIN_PULLDOWN | MUX_MODE2) 	/* PR1_PRU1_GPO12.MCBSP_CLKX */
			K2G_CORE_IOPAD(0x1348) (BUFFER_CLASS_B | PIN_PULLDOWN | MUX_MODE2) 	/* PR1_PRU1_GPO9.MCBSP_DR */
			K2G_CORE_IOPAD(0x1358) (BUFFER_CLASS_B | PIN_PULLDOWN | MUX_MODE2) 	/* PR1_PRU1_GPO13.MCBSP_FSR */
		>;
	};

2. i want to use McBSP in frame sync mode. How to configure McBSP in this mode? and which driver should i specify

&mcbsp {
	pinctrl-names = "default";
	pinctrl-0 = <&mcbsp_pins>;
	compatible = "ti,???";

    ????

	status = "okay";

    ????
};

Hello,

The McBSP pins are not connected in our HW on K2G to any codec or port. Also, I do not see any McBSP driver support on K2G.

Hello,Krunal Bhargav34

McBSP pins are routed to the "Serial expansion header" connector. And I want to connect ADS1278 to it. Maybe it don't need a driver? Any example for K2G + McBSP?

Hello,

Unfortunately, we do not have any examples related to McBSP and K2G.

Unfortunately, configuring McBSP pins is not possible because the mcpsb node is not defined in the device tree. I am using PROCESSOR-SDK-K2G for Linux.

I will probably have to use McASP or SPI ...
