Hi,
when I am specifying the camera GPIOs in the device tree like this:
gpio@2200000 {
camera-control-output-low {
gpio-hog;
output-low;
gpios = <CAM0_RST_L 0 CAM0_PWDN 0
CAM1_RST_L 0 CAM1_PWDN 0>;
label = "cam0-rst", "cam0-pwdn",
"cam1-rst", "cam1-pwdn";
};
};
The boot process hangs with mmc errors like this:
