UCD9081: UCD9081 can not be programmed.

Part Number: UCD9081

Hi,

I got a problem when I programmed the UCD9081.

I refer to the www.ti.com/.../slva275b.pdf#mce_temp_url# to program UCD9081 and followed the 3.7.1.
The User Data(0x1080~0x10FF) could be programmed successfully but the configuration section could not.

Do you have any idea on this issue?

    Hi yihe,

    Do you mean " 3.2 I2C Transactions "? If yes, I followed it exactly.
    I used the "SMBus & I2C & SAA Debug Tool" to send data to the device.
    I could receive version(0x55) and read out the User Data(0x1080~0x10FF) and configuration section(0xE000~0xE1FF).
    Those values were same with section 3.4.1 Factory Default.

    As I could program User Date successfully, it seems the I2C communicate was correct, am I right?

    Hello

    Are you able to program the same data(both user data and configuraton data) via the UCD9081 GUI on the same device?

    Hi Yihe,

    No, I don't have the UCD9081 EVM, so I could not use UCD9081 GUI to program it, but I could use
    the I2C and "SMBus & I2C & SAA Debug Tool" to test the device.

    I followed the following steps (section 3.7.1 UCD9081 I2C Transactions for Writing User Data and PARAMS) to write data to the device.
    a. set 0x2 to FLASHLOCK.
    b. send 0x1080 to WADDR.
    c. unlock and erase the flash. send 0xBADC to WDATA.
    d. send 0x1080 to WADDR.
    e. send 32 bytes to WDATA.
    ……
    b. send 0xE000 to WADDR.
    c. unlock and erase the flash. send 0xBADC to WDATA.
    d. send 0xE000 to WADDR.
    e. send 32 bytes to WDATA.
    ……
    set 0x0 to FLASHLOCK.
    Power cycly and read out.
    The User Data was correct but configuration section remained factory default values.


    Before setting the 0x0 to FLASHLOCK, I read the 0xE000~0xE1FF and the value was correct.
    However, after setting the 0x0 to FLASHLOCK and power cycle, the configuration section changed to the default values.

    The UCD9081 GUI supports UCD9081 and it does not require EVM. it shall work with your own board as long as USB-TO-GPIO Dongle is used.

    Fro the steps, i did not see any thing obvious wrong. you may delay the FLASHLOCK and recheck the value before the power cycle.

    Hi Yihe,

    I can use the UCD9081 GUI to read  and "Update Parameter and Sequexce" the UCD9081 device, and the waveform was correct.

    After finishing programming, I closed  the software and opened it again. The GUI failed to connect the device. But we found replacing a new IC could make it work.

    new IC cloud make it work.

    after finishing programming

    Hi Qian,

    Yes, I can' t program the 0xE000 to 0xE1FF
    I also experienced another issue during tests. After erasing 0xE000 to 0xE1FF, the next cmd became NACK.
    could you help to check if the following steps need to be modified?
    a. set 0x2 to FLASHLOCK and delay 1ms.
    b. send 0xE000 to WADDR. send 0x00 to 0x30 and 0xE0 to 0x31, and delay 1ms
    c. unlock and erase the flash. send 0xBADC to WDATA. send 0xDC to 0x31 and 0xBA to 0x32, and delay 2ms

    d. send 0xE000 to WADDR(NACK). send 0x00 to 0x30 and 0xE0 to 0x31, and delay 1ms

    Hi Yihe,

    I programmed the UCD9081 successfully(include 0x1080~0x10FF & 0xE000~0xE1FF).

    I can program the "EVM Default Configuration" to UCD9081, and then program our code to UCD9081.
    But I could not change it back to the "EVM Default Configuration".
    Is it correct?

    Regards,
    Raphael

    Hello Raphael
    Did you try the UCD9081 GUI? it has a option to load EVM Default Configuration.

    Hi Yihe,

    Yes, I tried to use the UCD9081 and click the Default Configuration.
    Those values(0xE000~0xE1FF) were not changed but the user data was successful.

    Regards,
    Raphael
