On the PocketBeagle, both I2C-1 and I2C-2 are both brought out to the
headers and both enabled by default.
I don't know that there is any reason to prefer one over the other on the
PocketBeagle.

This is the DTB file on the green downloaded yesterday.
I dont understand that if its disabled why is there a /dev/i2c-1 file ?
They fixed the numbering starting with the 9.1 images from what i can read.
If it needs to be enabled how would one go about enabling it ?

I2C-0 is intended for internal board management, so sort of reserved,
except as a last resort.
I2C-1 is available, but not enabled, on the BBB and is enabled/implemented
on the PocketBeagle, so you could always loo
I will keep looking into this.
more infos
I took the current DTB file and decompiled it
I looked at the I2C sections
i2c0 = "/ocp/i2c@44e0b000";
i2c1 = "/ocp/i2c@4802a000";
i2c2 = "/ocp/i2c@4819c000";
i2c@44e0b000 {
compatible = "ti,omap4-i2c";
More infos
after reading a bit and seeing where to look I may have found the error msg.

I was trying to add a i2c device to bbb. After several failed attempts, I
measured the power on the rail. The voltage
from pin0 to pin 3 shows 2.47v. As well frompin 0 to pin 5 which suppose to
be 5V DD
Can anybody with a green or black verify the odd behavior i am seeing on
my greens and blacks ?
I am using the latest IOT image
root@beaglebone:/home/debian# uname -r
4.9.78-ti-r94
I use i2ctools and issue the commands
root@beaglebone:/home/debian# i2cdetect -r 0

Thanks for those suggestions, but that's way too much work. I guess I'll just
