i2c devices

Code: Select all

# i2cdetect 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.
Continue? [Y/n] 
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Anybody know what this device is at address 0x64?

sensors-detect does not recognize it, and i cannot find any Linux i2c device driver which normally uses this address.

Are you on B3? Could it be the wifi card? There is nothing else connected on the I2C bus..

Hi Johannes

Yes, i'm on a B3.

WiFi? Is this the EEPROM containing the regulatory information?

Do you use a COTS card? Can you tell me what it is? Where i can get a data sheet?

Could be yes, I actually am not sure if those mini-PCI-x-cards we have use I2C, but it is specified in the connector and hence routed on the board to that connector.

The cards we use are Unex DXNA-92: http://www.unex.com.tw/product/dnxa-92
