Environment:
- Hardware: Lenovo ThinkPad X9 15
- Sensor: Sony IMX471 (via Intel IPU6 Bridge)
- OS: Arch Linux
- Kernel: 7.1.3-arch1-3
- Driver Version: ipu6-drivers (r273.c09fa9a6e)
- Pipeline: libcamera Software ISP
Description of the Problem:
On the Lenovo ThinkPad X9 15 the camera image is inverted by default in the all aplications (I use qcam to test).
When attempting to fix the orientation at the hardware/driver level (change props.rotatation=180) the physical rotation successfully occurs, but image was currepted: wrong pixels colors, defects as a grid of small blacks squares.
What I have tried:
- change props.rotation to 180. Didn't help, apears squares and changed color(I can't describe it in detail, it looks as picture become more dark-purple and dark-green)
- in
imx471_set_ctrl add without if-construction add imx471_set_ctrl_hflip and imx471_set_ctrl_vflip. In imx471_set_ctrl_vflip delete two lines with imx471_read_reg and imx471_write_reg with IMX471_REG_V_WIN_OFFSET
Didn't help as I wan't, didn't apears squares, but change color (red and blue change swapped). And when I reopened qcam one more time, All changes were disapered, And image became just inverted: inverted in orientaion, but colors were normal
- change
IMX471_REG_ORIENTATION to 0xffff 0x0103 0x0000 0x0100 0x0102. Didn't help, I didn't see any differences. Picture was just inverted.
To change driver I use:
sudo dkms remove ipu6-drivers/r273.c09fa9a6e --all
sudo dkms build ipu6-drivers/r273.c09fa9a6e -k $(uname -r)
sudo dkms install ipu6-drivers/r273.c09fa9a6e -k $(uname -r)
sudo modprobe -r imx471 && sudo modprobe imx471
