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
