I2C analysis
Using I2C tools you can analyze the I2C bus:
root@beagleboard:/bin# i2cdetect -l i2c-1 i2c OMAP I2C adapter I2C adapter i2c-2 i2c OMAP I2C adapter I2C adapter i2c-3 i2c OMAP I2C adapter I2C adapter
Zippy Board uses i2c-2 for the RTC and EEPROM:
root@beagleboard:/bin# i2cdetect -y -r 2 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: 50 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --
- EEPROM is at 0x50
- RTC is at 0x68
EEPROM
AT24 EEPROM (AT24C01B) is used to identify Zippy board. See expansion board how this is done.
Using Linux i2cdump tool at bus 2 address 0x50 the content of this EEPROM is given:
root@beagleboard:~# i2cdump 2 0x50 b 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 00 01 00 01 01 00 00 00 ff ff ff ff ff ff ff ff .?.??........... 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ 80: 00 01 00 01 01 00 00 00 ff ff ff ff ff ff ff ff .?.??........... 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................
