Original question:

UCD9090: i2c/PMBus programming

UCD9090: In circuit programming tools requirements

Part Number: UCD9090
Other Parts Discussed in Thread: USB-TO-GPIO2,

Hi Experts,

Seeking your assistance on this query from Cx:

"We have to program UCD9090Q in circuit. We have testpoint on pins PMBUS_CLK ,PMBUS_DATA, PMBUS_ALERT , PMBUS_CNTRL.
Please define what programmer tool can we use as hardware and software too."

I am seeing THIS post. Do you think Fusion Digital Power Studio and USB-TO-GPIO2 are enough to the customer for their design?

Also, let me know what else we have to offer for the betterment of their design.

Thank you.

Regards,
Archie A.

    Thanks, Anne.

    Other than these tools, do you have any suggestions based on this request?

    So, they can use those tools given the tests points they already designed, correct?

    Hi, Archie,

    If you use TI UCD9090 EVM board, when USB2GPIO2 adapter connects to device, the PMBUS_CLK, PMBUS_DATA, PMBUS_ALERT, and PMBUS_CTRL pins are connected to device's. If you don't use TI EVM board, then connect those pins to USB2GPIO2 adapter's pins according to USB-TO-GPIO2 user guide document. So yes, they can use those tools.

    Hi Anne,

    Need your assistance again.

    We've read from several threads here that GUI's user's guide specific for UCD9090 is accessible within GUI itself. But couldn't find it in the app.  Is GUI user's guide downloadable separately now?

    We have attached the schematics part of the mentioned UCD9090, please check if this can work with the tools advised. Also, can you confirm if we can use UCD9XXX Device GUI / Flash / Firmware download to flash the sent content into our UCD9090?

    Without this information customer cannot decide what tool to order.

    Regards,
    Archie A.

    UCD9XXX Device GUI/Flash/Firmware download, etc. are Fusion Digital Power Designer tools. In Fusion GUI window, click on Help menu, then you can Sequencer help files.

    Hi, Archie,

    Do you any pullup resistors on DATA, CLK, and ALERT pins? If you don't have any pullup resistors on those pins, please change the adapter ALERT, CLOCK, and DATA pullup to 2.2 kΩ as shown in the below screenshot. UCD9090 might be in ROM mode, or Program mode => If device is not found in ROM mode scanning, then try to scan device in Program mode by click on "DEVICE_ID" link.

    Hello Anne,

    I found a way how to program the UCD9090 with Fusion Design Online GUI. But it needs a lot of interactions. Is there any way to load a give .hex into the UCD9090 ? Can it be done from a win batch file ?  Is there  a command line interface?

    Thank you,

    Archie A.

    Hi, Archie,

    Fusion GUI supports command line interface => it can be done from a win batch file. You can get the Command Line Tools document from Fusion GUI Help menu.

    Another tool to download the configuration is "Firmware & Configuration Download Tool". Deselect "Firmware Download" check box and select downloading Data Flash File.
