I have an application where I (currently) need to access the I2C GP2 bus but haven’t been able to do that so far. I have verified that I can communicate in some manner with GP0, GP1, and GP3 by using i2cdetect and looking for clock signals with my oscilloscope but I see nothing for GP2. I’m currently working with the TX2 development kit so this isn’t an issue with custom hardware.
Is there some sort of config file that I need to set up to enable this bus?
Am I just looking at the wrong port through i2cdetect? I have found that GP1 is on bus 0, GP0 is on bus 1, and GP3 is on bus 8. i2cdetect -l shows available busses from 0 to 8 and 40 to 47. I’ve tried them all but maybe I’m missing something?
Any help that can be provided would be appreciated.
