Dear forum,
i compiled stock recent kernel "linux-stm32mp-6.1.28-stm32mp-r1-r0",
https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernel
i tried to boot compiled kernel i got error: gc2145@3c node not found - DT update aborted
... and then kernel hangs with message: "Starting kernel ..."
command : dtc -I dtb -O dts stm32mp135f-dk.dtb
shows:
Warning (unique_unit_address): /soc/etzpc@5c007000/i2c@4c006000/gc2145@3c: duplicate unit-address (also used in node /soc/etzpc@5c007000/i2c@4c006000/camera@3c)
and then later below:
gc2145@3c {
compatible = "galaxycore,gc2145";
reg = <0x3c>;
clocks = <0x3d>;
IOVDD-supply = <0x25>;
AVDD-supply = <0x25>;
DVDD-supply = <0x25>;
powerdown-gpios = <0x33 0x03 0x01>;
reset-gpios = <0x33 0x04 0x01>;
status = "okay";
phandle = <0xac>;
port {
endpoint {
remote-endpoint = <0x3e>;
clock-lanes = <0x00>;
data-lanes = <0x01 0x02>;
phandle = <0x3b>;
};
};
};
camera@3c {
compatible = "ovti,ov5640";
reg = <0x3c>;
clocks = <0x3d>;
clock-names = "xclk";
DOVDD-supply = <0x25>;
status = "disabled";
powerdown-gpios = <0x33 0x03 0x01>;
reset-gpios = <0x33 0x04 0x01>;
phandle = <0xad>;
port {
endpoint {
clock-lanes = <0x00>;
data-lanes = <0x01 0x02>;
phandle = <0xae>;
};
};
};
please could you help me fix that issue ? ... camera should be enabled and kernel should not hang ...
