Dear Meta-TI Team Member,
I want to use 4 GPIO pins of my beaglebone black,
Here's my dts code :
==========
gpio0_pins: gpio0_pins {
pinctrl-single,pins = <
AM33XX_IOPAD(0x840, PIN_INPUT_PULLUP | MUX_MODE7)
/* gpmc_a0.gpio1_16 */
AM33XX_IOPAD(0x844, PIN_OUTPUT_PULLDOWN |
MUX_MODE7) /* gpmc_a1.gpio1_17 */
AM33XX_IOPAD(0x878, PIN_OUTPUT_PULLDOWN |
MUX_MODE7) /* gpmc_be1n.gpio1_28 */
AM33XX_IOPAD(0x9A4, PIN_OUTPUT_PULLDOWN |
MUX_MODE7) /* mcasp0_fsr.gpio3_19 */
>;
};
// Added GPIO0 node, experiment by Riko Ho 7 July 2017
&gpio0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&gpio0_pins>;
};
=======
I can see it already, are they correct ?
root@beaglebone:/sys/kernel/debug/pinctrl/44e10800.pinmux# cat
pinmux-pins | grep "gpio0"
pin 16 (PIN16): 44e07000.gpio (GPIO UNCLAIMED) function gpio0_pins group
gpio0_pins
pin 17 (PIN17): 44e07000.gpio (GPIO UNCLAIMED) function gpio0_pins group
gpio0_pins
pin 30 (PIN30): 44e07000.gpio (GPIO UNCLAIMED) function gpio0_pins group
gpio0_pins
pin 105 (PIN105): 44e07000.gpio (GPIO UNCLAIMED) function gpio0_pins
group gpio0_pins
==========
I got :
//omap_gpio 44e07000.gpio: could not find pctldev for node
/ocp/l4_wkup@44c00000/scm@210000/pinmux@800/gpio0_pins, deferring probe,
When the board boots, is it ok ? Or I miss something, please advice, thanks.
