AM437x Starter Kit GPIO and PWM

Pedro Freire

Hi,

I would like to use the pins of the J10 header of the development board AM437x Starter Kit, but i am not having any success configuring the pins.

In order to configure the pins i add the following to .../arch/arm/boot/dts/am437x-gp-evm.dts

	hardware_pins: hardware_pins {
		pinctrl-single,pins = <
			0x000 MUX_MODE7		  /* gpmc_ap0.gpi01_0 */
			0x150 MUX_MODE7		  /* spi0_sclk.gpi0_2 */
			0x1A0 MUX_MODE9		  /* mcasp0_aclkr.gpi0_18 */
			0x1AC MUX_MODE9		  /* mcasp0_ahclkx.gpi0_3 */
			0x1A8 MUX_MODE9		  /* mcasp0_axr1.gpi0_2 */
			0x1A4 MUX_MODE9		  /* mcasp0_fsr.gpi0_19 */
			0x26C MUX_MODE9		  /* spi2c_cs0.gpi0_23 */
			0x264 MUX_MODE9		  /* spi2_d0.gpi0_20 */
			0x268 MUX_MODE9		  /* spi2_d1.gpi0_21 */
			0x260 MUX_MODE9		  /* spi2_sclk.gpi0_22 */
		>;
	};

Then i tried to compile this file using the command:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am437x-gp-evm.dtb

Copied the am437x-gp-evm.dtb to targetfilesystem/boot

Finally, while trying to define the pin values under /sys/class/gpio i couldn't get the right value on the J10 connector.

Could anyone explain me the right way to configure the pins multiplexer and how to activate the pwm modules? An example will be fantastic.

Thanks,

Pedro

I already got control over the above pins, including the PWM. It was needed to change the /boot/uEnv.txt file.

fdtfile=am437x-sk-evm_new.dtb

And i have change the .dts file like this:

I think that this isn't the right way to configure this, but it worked. I just defined the pins inside &am43xx_pinmux, and then at the end i set those pins configuration with this:

&gpio5 {
	pinctrl-names = "default";
    	pinctrl-0 = <&hardware_pins>;
	status = "okay";
};

How is the right way to do it?

thanks,

Pedro

Hi Pedro,

If your goal is to control these pins (toggle their output) with GPIO sysfs entry, then the above approach should be OK.

Best Regards,
Yordan
