Question
i2c Arbitration lost
posted in IGEPv2

I am trying to connect a device to the i2c_2 pins on the IGEPv2. When I try to detect it with
i2cdetect -r 0
I get the message
omap_i2c omap_i2c.2: controller timed out
When I disconnect everything from the IGEP J990 pins and again try
i2cdetect -r 0
I get the message
omap_i2c omap_i2c.2: Arbitration lost
Normally I would expect a list of addresses probed with nothing at any of them. The internet suggests this means 2 MCU's are competing for the bus?
I am unsure of the cause. dmesg and the i2cdetect results are attached.
