Arducam 64MP Quad I2C Issues

After I got my 64MP cams running on the RPI 5 I am facing issues with the I2C bus.
I have activated the bus in the config.txt and I have connected (after removing the Quad-Hat) a BME280 Sensor. The Sensor was directly recognized.
But when attaching the Arducam Hat the i2cdetect -y 1 does not show any sensors.
I have reduced speed on the Bus to 1khz but no change.

Does anyone have encountered similar issues and has any ideas for me?

Hi @camman
If you connect the camera to the CAMERA 1 port, you can try the command ** i2cdetect -y 6**.
If you connect the camera to the CAMERA 0 port, you can try the command ** i2cdetect -y 4**.

Thanks for the hints.
So, yes, I have Bus 4. When detaching Camera, the detect shows foto@foto:~ $ i2cdetect -y 4

 0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

00: – – – – UU – – –
10: – – – – – – – – – – – – – – – –
20: – – – – – – – – – – – – – – – –
30: – – – – – – – – – – – – – – – –
40: – – – – – – – – – – – – – – – –
50: – – – – – – – – – – – – – – – –
60: – – – – – – – – – – – – – – – –
70: – – – – – – – –

When attaching camera, the detect shows
foto@foto:~ $ i2cdetect -y 4
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – – – – UU – – –
10: – – – – – – – – – – UU – – – – –
20: – – – – 24 – – – – – – – – – – –
30: – – – – – – – – – – – – – – – –
40: – – – – – – – – – – – – – – – –
50: 50 – – – – – – 57 – – – – – – – –
60: – – – – – – – – – – – – – – – –
70: – – – – – – – –

So something has happend. But there is no address 10 and the configuration does not work:
foto@foto:~ $ i2cset -y 10 0x24 0x24 0x02
Error: Could not open file /dev/i2c-10' or /dev/i2c/10’: No such file or directory

At least that is what I understand works for selection cameras as described in Quick Start Guide for Arducam CamArray HAT Kit - Arducam Wiki

Or are there new addresses or other commands available? My goal is to select the each camera seperatly, I am using the hat to get the four cameras one by one…

done, again me beeing stupid → here if you encounter same issue:
The Device address is the first byte, not the number which actually is the bus:

i2cset -y 4 0x24 0x24 0x02
4 → Bus
0x24 Device… wrong syntax, my fault again.

Yeahh, that’s I wanted to say. Sorry for the omitting before.
