Part Number: UCD90124A
Other Parts Discussed in Thread: UCD90120A

Hi Sir, 

We are developing the UCD90124A off-line programming algorithm, we'd like to apply for the latest firmware for Pflash. Can you share with us the Pflash firmware file and also the device ID. 

Thank you.

    Hi

    Firmware is programmed by TI at the final test stage and customer shall not touch.

    Customer shall only program the data flash section

    Could you tell the reason to program pflash?

    Regards

    Hi Yihe, 
    Yes. The customer will also program the Dflash area. 
    We get the samples from customer and we'd like to check if the fimrware in Pflash is valid. That's the reason why we'd like to apply for the firmware file for Pflash. 
    Or can you advise the Pflash checksum value, we can compare with the samples. Thank you.

    HI

    You can read the DEVICE_ID(0xFD) command to confirm the revision.

    UCD90124A shall return below.

    0x5543443930313234417C322E342E302E303030307C31313131323100

    Hi Yihe, 
    Thanks for share the device ID information. Actually, our enginere has tried this command but we can't get response from the device after write back the Pflash checksum back to Pflash area. 
    But when we change the Pflash firmware to UCD90120A then the operation is normally.
    It's the reason why we'd like to apply for the Pflash firmware file for UCD90124A. 
    If the Pflash firmware file can't be shared. Can you assist to check the Pflash firmeware checksum?
    Thanks for your support and nice to work with you once again.

    Hi

    Checksum for UCD90124A is 0x002E6350. 

    Checksum for UCD90120A is 0x0036921D.

    Why do you want to write the checksum? if checksum is wrong, device stays at ROM mode.

    Hi Yihe, 
    Thanks for share the Pflash checksum.
    We leveraged the ROM to program the Dflash and need to recreate the Pflash checksum in the programming procedure. 
    We willl try with Normal mode to program the Dflash. Thanks again.

    Hi

    Shall not use ROM to program data flash. That is very old requirement on the 1st Gen UCD.

    You can use normal mode for UCD90124A.
