6.What problems are you experiencing?
The problem I am running into is that I am not able to set the focus of the motorized lens on either of my two IMX477 cameras. For some reason on this carrier board, the cameras appear on address 0x64, on buses 7 and 8. I verified this by plugging and unplugging the cameras and saw the devices disappear when the cameras were unplugged (address change perhaps due to the mux but idk).
I tried to run the following commands:
- “sudo i2cset -y 7 0x0c 0 160”
- “sudo i2cset -y 7 0x64 0 160”
- “sudo i2cset -y 8 0x0c 0 160”
- “sudo i2cset -y 8 0x64 0 160”
I also tried running the Focuser.py class to focus the camera that didn’t with either even when I changed the chip address in Focuser.py. Every attempt resulted in an Error: Write failed. I also tried using the smbus2 library in python and that didn’t work either.
dmesg output:
[ 2307.081360] tegra-vii2c 546c0000.i2c: no acknowledge from address 0x64
[ 2344.048234] tegra-vii2c 546c0000.i2c: no acknowledge from address 0x64
I tried changing the bus speed to 100khz but that didn’t help either.
Running the command: i2cdetect -r -y 7 gave me this out put:
