I have a Colibri T30 on the Iris Carrier board running linux.
Please see attached file. This is the output when I type i2cdetect -y 0
I have no devices on the I2C bus. I was expecting a small table for output with nothing shown (accept --) for address 00 to 70. Can you please let me know how to interpret the output? Am I missing something in hardware i.e. pull-up/down resistors on the I2C_SDA and I2C_SCL pins?
I am using the X16 connector on Iris board, Pins 5 and 6 are the I2C pins.
Can you check by logging in using ssh or using the terminal on LXDE desktop? The messages you see are debug messages from the I2C driver for addresses it does not get an ACK for. Logging in over SSH or using the terminal on LXDE desktop will not show these messages.
SSH session works as you described. Thanks for the prompt response.
