Luckfox Forums

I have successfully flashed my Luckfox Pico Pro Max with the stock OS images, which are available on Google Drive. With this image installed, I am able to communicate with the camera.

I see files located in /userdata/ and /dev/video0 is populated.

However, when I use the SDK to do my own buildroot compilation and install, and then flash the image, the camera is not available.

Which packages must be enabled in: `./build.sh buildrootconfig` in order to enable the camera?


More details about buildroot `.config`:
```
$ cat sysdrv/source/buildroot/buildroot-2023.02.6/.config | grep "CAMERA"
BR2_PACKAGE_LIBCAMERA_ARCH_SUPPORTS=y
BR2_PACKAGE_LIBCAMERA=y
BR2_PACKAGE_LIBCAMERA_V4L2=y
BR2_PACKAGE_LIBCAMERA_HAS_PIPELINE=y
# BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI is not set
BR2_PACKAGE_LIBCAMERA_PIPELINE_RKISP1=y
# BR2_PACKAGE_LIBCAMERA_PIPELINE_SIMPLE is not set
# BR2_PACKAGE_LIBCAMERA_PIPELINE_UVCVIDEO is not set
# BR2_PACKAGE_LIBCAMERA_PIPELINE_VIMC is not set
# BR2_PACKAGE_LIBCAMERA_COMPLIANCE is not set
# BR2_PACKAGE_LIBCAMERA_APPS is not set
```

```
cat sysdrv/source/buildroot/buildroot-2023.02.6/.config | grep "RKISP"
BR2_PACKAGE_LIBCAMERA_PIPELINE_RKISP1=y
```

I just wanted to add some additional info here:

Here is my `/etc/luckfox.cfg` file:

```
SPI0_M0_CS_ENABLE=1
SPI0_M0_MODE=1
SPI0_M0_STATUS=1
SPI0_M0_MISO_ENABLE=0
SPI0_M0_SPEED=40000000
CSI_ENABLE=1
UART4_M1_STATUS=0
PWM11_M1_STATUS=0
PWM10_M1_STATUS=0
PWM9_M1_STATUS=0
PWM8_M1_STATUS=0
PWM0_M1_STATUS=0
PWM11_M2_STATUS=0
I2C3_M1_STATUS=0
I2C3_M1_SPEED=0
I2C1_M1_STATUS=0
I2C1_M1_SPEED=0
```

In the end, I got it.

It seems like LIBCAMERA_APPS was the missing one.

```
BR2_PACKAGE_LIBCAMERA_ARCH_SUPPORTS=y
BR2_PACKAGE_LIBCAMERA=y
BR2_PACKAGE_LIBCAMERA_V4L2=y
BR2_PACKAGE_LIBCAMERA_HAS_PIPELINE=y
# BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI is not set
BR2_PACKAGE_LIBCAMERA_PIPELINE_RKISP1=y
# BR2_PACKAGE_LIBCAMERA_PIPELINE_SIMPLE is not set
# BR2_PACKAGE_LIBCAMERA_PIPELINE_UVCVIDEO is not set
# BR2_PACKAGE_LIBCAMERA_PIPELINE_VIMC is not set
BR2_PACKAGE_LIBCAMERA_COMPLIANCE=y
BR2_PACKAGE_LIBCAMERA_APPS=y
```

In the end, I DONT GOT IT.

The above configuration, does work using SPI flash, but in MicroSD mode, it does not work.

I am quite stumped at this point.

Hello libcamera is suitable for Raspberry Pi or related ISP products, Luckfox Pico uses the ISP developed by rockchip, buildroot adds LIBCAMERA and cannot be used on RV1103/RV1106, The use of the camera has been described in https://wiki.luckfox.com/Luckfox-Pico/L ... CSI-Camera, please attach the test method you used or the relevant logs
