Hi,

can anybody tell me [1] which baud i2c-(7) on radxa rock 4 uses? And [2] how I am able to change that?

Double posting:

You'd need to adjust the device tree, or better create an own device tree overlay to enable i2c7 but also change its frequency. Could you check:

ls -l /proc/device-tree/i2c@ff160000/
cat /proc/device-tree/i2c@ff160000/*frequency*
