UCD90160A: Are flash exports in HEX format from UCD90160 cross-compatible with the updated UDC90160A ?

Part Number: UCD90160A
Other Parts Discussed in Thread: UCD90160

Hi,

according to section 3.5 of SLUA815 to avoid toggling of GPO ports during programming of PMBus command I need to program the device in my application via HEX file.

As HEX files can for some reason only be exported from a live device, I am wondering whether the file I would generator on my current EVAL board with a UDC90160 installed would be compatible to the UCD90160A device in my final design or would I need to install a A-device in the EVAL board as well ?

Best regards

Bjoern

    Hi Bjoern
    No, Hex file is not compatible between UCD90160 and UCD90160A. downloading hex file from UCD90160 into a UCD90160a device will not work.
    The workaround is to generate a new hex file from ucd90160a:
    1. export a project file from UCD90160
    2. import the project file into UCD90160A. project file is compatitble.
    3. export the hex file from UCD90160A.

    Hi Yihe,

    thank you ! I will then put the A-Device in my EVM to generate a new HEX file for writing to my PCB with A-Device on it !

    Cheers
