-There are three chips which are connected to the main CPU's SCL/SDA pins.
-So far, it's unknown which device is responsible for which I2C output.

to USB.
The logic analyzer used for capturing was a Saleae Logic:
The sigrok command line used was:
- sigrok-cli -d 0:samplerate=4mhz --time 120s
- -p '4=SCL,6=SDA' -o trekstor_ebr30_a_i2c_30s.sr
+ sigrok-cli -d 0:samplerate=4mhz --time <time>
+ -p '4=SCL,6=SDA' -o <filename.sr>
