I2C working on1 out of 4 OMEGA2+ [RESOLVED]

  • A

    Hello.

    I have 4 Omega2+ and on 3 of them I cannot access the i2c. With i2cdetect -y 0 I get
    the 30 ...37 and 50 ...5f. On the one that is working I can see the device connected as expected:
    root@Omega-xxxx:~# i2cdetect -y 0
    0 1 2 3 4 5 6 7 8 9 a b c d e f
    00: -- -- -- -- -- -- -- -- -- -- -- -- --
    10: UU -- -- -- -- -- -- 17 -- -- -- -- -- -- -- --
    20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    70: -- -- -- -- -- -- -- --

    I get the same result if I SSH or connect through the serial port.

    I am wondering if I did install a package on the working one and forgot?
    Any suggestion? Any help is appreciated.

    Thanks.

    More correctly you should have written:
    I have 4 Omega2+ and I2C works on each of them but the output of the i2cdetect command wrong on 3 of them.
    i2cdetect(8) - Linux man page

    I am wondering if I did install a package on the working one and forgot?

    You updated the firmware to v0.2.0 b194 only on the "working one" - the others have some older FW.
    Please check it with oupgrade -v.

    You are correct. I checked the firmware on the one with the correct i2cdetect output,
    it is Version: 0.2.0 b194 while the other ones are : ' 0.1.9 b159' but after doing 'oupgrade' it is now 0.1.10 b160 and not 0.2.0 b194

    Doing 'oupgrade' again give this message:
    ~# oupgrade

    Device Firmware Version: 0.1.10 b160
    Checking latest version online...
    Repo Firmware Version: 0.1.10 b160
    Comparing version numbers
    Device firmware is up to date!

    I guess it fetches the upgrade from the wrong place. Any further suggestion?

    Thanks for the help.
