Hi,
I've been having a hell of a time getting the BeagleBone Green to see Grove
devices connected to it.
Running i2cdetect -r 0 results in the following output regardless of which
Grove sensors are connected:
# i2cdetect -r 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0 using read byte commands.
I will probe address range 0x03-0x77.

Similarly, i2cdetect -r 1 always results in the following output:
# i2cdetect -r 1
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-1 using read byte commands.

I tried reflashing my board with the 2015-07-28 eMMC Flasher (console)
image. My current uname -a output is: Linux greenbone 3.8.13-bone72 #1 SMP
Tue Jun 16 21:36:04 UTC 2015 armv7l GNU/Linux.
However, flashing did not help.
I also tried on a second board. Same problem.
The BBG Alarm System code
<https://github.com/Lee-Kevin/BBG_Alarm_system_IoT> posted on the BBG
product page also will not run.
Am I doing something wrong?
Thank you,
Ben
