No carga mi archivo dts - **Help**

Cree un archivo dts para configuracion de pines y pps para un gps, pero al probar el
ls /sys/devices/platform/ocp/ | grep GPS
No me da ninguna salida.
Probando ls /lib/firmware/ si aparece el archivo creado.

/dts-v1/;
/plugin/;

despues use Use
dtc -I dts -O dtb -o GPS.dtbo GPS.dts
sudo cp GPS.dtbo /lib/firmware

Lo tengo agregado en el uEnv.txt

uboot_overlay_addr0=/lib/firmware/GPS.dtbo
reinicies con sudo rebot

Quize configurar lo pines como P9_11 (PIN_MUX6) pero me da error de escritura
Para esta configuracion volvi a flasear la sd con la ultima imagen de la BeagleBone Black, sin hacer update ya que con update da el mismo problema

… P8_07 should be free…

Please report the output of:

sudo /opt/scripts/tools/version.sh

Edit, probally wrong pin…

bb_gps_pps_pins: pinmux_bb_gps_pps_pins {
                pinctrl-single,pins = <
                    0x0E4 0x27 // P8_7 pps
 >;

P8_07 → 0x090
0x0E4 → P8_29

Are you using P8_07 or P8_29?

Regards,

Gracias por la pronta solución, también corregí los pins P9_11 Y 13.
Al probar dmesg ahora da estos nuevos errores tomados de diferentes líneas, es de mi interés tomar la señal pps del P8_07 corregida a P8_07 → 0x090

Sorry missed that too, missing “0”… “P8_07”

Change

P8_7_pinmux {status = "disabled";};

to:

P8_07_pinmux {status = "disabled";};
