    Hi Nogueira,

    There may be a few possible paths of failure here, however, from your question, (1) seems most likely:

    1) Ensure the EV2300 is connected to the EVM via SMBus connectors. The bq30z55 gauge does not use I2C.
    2) Ensure the EV2300 is connected via USB to the computer and that your computer is running EVSW
    3) Ensure the EV2300 is up to date. If the EV2300 is version 3.1C, it will require updating using this package: e2e.ti.com/.../3225.EV2300FWUpdaterUnprogDev.zip
    4) Ensure the bq30z55EVM is powered via a battery or a battery simulator. For more information on how to connect the EVM, please refer to the User's Guide found here: www.ti.com/.../sluu516.pdf

    With respect to converting I2C to SMBus, this is possible with a few modifications to the host driver. Some good examples of using the I2C interface on an MSP430 as an SMBus interface may be found here: processors.wiki.ti.com/.../Implementing_SMBus_using_USCI

    Sincerely,
