TPS53688: BAD DATA LENGTH programming error

Cosmin P

Part Number: TPS53688

Tool/software:

Hello,

Customer proto manufacturing needs support on TPS53688 programming error reporting: BAD DATA LENGTH.

This error, is causing TI FUSION DESIGNER software to not able to detect any devices until the TI dongle USB is I reinitialize (unplug/plug)…
Attachined a sample output from the programming and the program file.

 The programming command : FusionConfigWriter --address 119 --project --infile ""C:\NTFW\Load\NTK710CA\TPS53688\TP53688_119d.xml"" --force-write --erase-data-flash-before-importing 0xff --reset-when-done always

Can you please advise

Thank you

    Hi,

    Our expert on device programming and Fusion is currently out of office. I will look at your program file and check with the rest of the team, but we may not be able to provide an answer until they return.

    Regards,

    Troy

    Hi Cosmin,

    Since this error first occurs while importing a new configuration, you can try importing a NVM Config File to your device to prevent the error occurring.

    To do this you will need to export the NVM Config File from an online device by first opening the device configuration in Fusion GUI and then going to: File -> Export -> NVM Config File. Then select to import this file, while connected to a new device, in the GUI.

    You may alternatively try adding the following flag to your command: --import-using-nvm-data true, giving:

    FusionConfigWriter --address 119 --project --infile ""C:\NTFW\Load\NTK710CA\TPS53688\TP53688_119d.xml"" --force-write --erase-data-flash-before-importing 0xff --reset-when-done always --import-using-nvm-data true

    Additionally, please find the NVM Programming Guide for VR13 Controllers at the following link, for your reference: https://www.ti.com/lit/an/slua888/slua888.pdf 

    Regards,

    Troy
