Other Parts Discussed in Thread: LMK03328EVM, LMK03328

New LMK03328EVM purchased, Connected with USB cable to the PC(USB identify working)

HWCTRL = 0,RSEL = 1, GPIO0 = 1, GPIO1 = 0, GPIO2 = 1, GPIO3 = 1, GPIO4 = 1, GPIO5 = Mid

Default EEPROM settings seem to working for all EEPROM pages (probing the output ports with a scope)

Want to update an EEPROM page, using codeloader4 outputs tab but cntrl+r showing all ports as disabled/greyed. 

Tried to program new settings on an EEPROM page using codeloader4 EEPROM tab, but its not overwriting the default  settings already programmed in the EEPROM,

please help

Regards, 

Kiran

    Hello Kiran,
    did you also connect the power for the LMK03328 on J3?
    Please refer to the EVM user guide (SNAU184) section 5 for details.

    Please let me know if that helps.

    Best regards,
    Patrick

    If CTRL+R is not updating the GUI to reflect the device register settings, I believe the GUI is not communicating with the device I2C interface (even though USB communication with the MCU is working).l

    In the GUI's Port Setup tab, click "Scan I2C Bus" to find the device.  It should find it at address 0x54 when GPIO1=0.  Then, you should be able to do CTRL+R to update the GUI with device's current register settings.

    You can follow the EEPROM programming flow described in section 12.1 in the EVM Software User's Guide: www.ti.com/lit/pdf/snau185

    Thanks Alan,

    That fixed the problem, ("Scan I2C Bus" -> After clicking a couple of times)

    Regards
