@natzguk Raspberry Pi 5 is special, its i2c bus is 4 and 6. meanwhile, Raspberry Pi need to configure the parameters in advance, please refer to this link below: https://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi#Raspberry_Pi_5_Setting

@natzguk pls try this: https://github.com/veyeimaging/rk35xx_firefly/blob/main/linux/samples/gstreamer/veye camera/preview.sh

@veye_xumm For anyone else. This works perfectly. Note that when recompiling on 64-bit Pi, the following warning is produced. It still builds. Just copy the outputs to bin and the scripts work fine. ./make.sh i2c_read.c: In function ‘main’: i2c_read.c:112:35: warning: passing argument 4 of ‘i2c_rd’ from incompatible pointer type [-Wincompatible-pointer-types] 112 | i2c_rd(fd, device_addr,reg_addr, &value, num); | ^~~~~~ | | | unsigned char (*)[512] i2c_read.c:20:68: note: expected ‘unsigned char *’ but argument is of type ‘unsigned char (*)[512]’ 20 | static int i2c_rd(int fd, uint8_t i2c_addr, uint16_t reg, uint8_t *values, uint32_t n)

@natzguk I believe the code is compatible. You can refer to the following link and try compiling it yourself: https://wiki.veye.cc/index.php/Build_drivers_from_source_for_rpi
