TMS570 MCU Development Kit blocked

Other Parts Discussed in Thread: UNIFLASH

Hi there!!

I have a TMS570 MCU DK with a TMS570LS20216SZWT MCU. On this board I managed to run an application which sends continuous data to UART, so sends continuous data through FTDI. I tried to reset the MCU before an erase with  CCS UniFlash, but no success. If you have any ideas please share it with me.

Thanks! Mihai

    Is there a chance to program or to erase the MCU direct or through an simple electronic circuit or to connect to special pins from MCU?

    Hi Mihai,

    Are you having trouble resetting the part or erasing the part? Can you connect to the part with CCS? If so, then you can halt the CPU, and erase the flash from within CCS, or quit CCS and erase using Uniflash.

    Let me know if this works.

    Regards, Sunil

    Hi Sunil,

    I tried everything... :) I tried program with CCS, with UniFlash, to hold the reset button when I tried to erase the target with UniFlash. The answer from debugger is: Error connecting to the target:
    (Error -151 @ 0x0)
    One of the FTDI driver functions used during
    the connect returned bad status or an error.
    The cause may one or more of: invalid XDS100 serial number,
    blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.
    Use the xds100serial command-line utility in the 'common/uscif'
    folder to verify the XDS100 can be located.
    or
    [16:29:03] FATAL >> IcePick: Error connecting to the target: (Error -151 @ 0x0) One of the FTDI driver functions used during the connect returned bad status or an error. The cause may one or more of: invalid XDS100 serial number, blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable. Use the xds100serial command-line utility in the 'common/uscif' folder to verify the XDS100 can be located. (Emulation package 5.1.600.0).

    From what I am seeing is like the target is not connected to the USB port. I can send you the whole project...

    Thanks for your help...

    P.S. xds100serial.exe shows nothing.
