MCF8316AEVM: cannot read or write EEPROM

Part Number: MCF8316AEVM
Other Parts Discussed in Thread: MCF8316A

Hi team,

Here's an issue from the customer may need your help:

The evaluation board does not work.

After power-on, the GUI communication status is normal and the D6 cycle blinks. Read and write EEPROM or motor parameters, using E2PROM as an example, a red prompt box pops up in the lower left corner of the GUI:! Inital Read failed   X

The prompt box then changes to the “Hardware not Connected" and a dialog box pops up in the middle of the GUI: "Connectivity issue There is an issue with the device connectivity. Please restart the GUI. OKAY"

The problem persists after restarting the GUI. Could you help check this case? Thanks.

Best Regards,

Cherry

  • Hi Cherry,

    Could you please help confirm:

    • Is the device marking "MCF8316A" or "PMCF8316A" on the EVM?
    • Which GUI version is the customer using?
    • Have they communicated with the EVM and written to the EEPROM successfully before?
    • After they power cycle the EVM and connect to the GUI, the customer can click the "Find Address" button in the GUI to ensure that the GUI is using the matching I2C address that the MCF8316A is configured with

    Regards,
