IWR1443BOOST: XDS110 debug probe question

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: UNIFLASH, , IWR1443

Hi 

We try use Uniflash to flash IWR1443boost with TI xds110 debug probe (turned off the power on board XDS110 (turn off 3v3_brd)), the flash failed at start loading the image, we be able to see the COMUart ort and  COM data port. Any one know why?

Thanks,

    Hello,
    If you connected the XDS110 debug probe to the BP/LP connector, you need to move the resistors from onboard XDS110 to BP/LP.
    - remove R30 AR_TDI,
    - remove R69, AR_TMS
    - remove R70, AR_TCK
    - remove R71, AR_TDO_SOP0
    - remove R136 - MSS_LOGGER
    - remove R128, R129 RS232Tx and RX232Rx
    - remove R80 XDS_NRST (may not need to be removed)

    You need to make up a test cable to HD60 connector, or access the appropriate resistor
    - AR_TCK - R66 ,J1-6
    - AR_TMS - R65,J1-6
    - AR_TDO_SOP0, R67, J1-4
    - AR_TDI, R29, J1-5

    You need to connect the equivalent BP/LP resistors, or connect the XDS110 probe to BP /LP connector
    - Aux RS232 Rx input - for Visualizer ( connect to ) J5-9, install R26
    - RS232Rx (connect to RS232Tx on debug probe) install R166, J6-7
    - RS232Tx (connect to RS232Rx on debug probe) install R169, J6-5
    - JTAG nRESET connect to J5-10 (AR_nREST_MCU)

    Hi Joe,
    We did pretty much as you suggested above, the only different is we connect JTAG nRESET to AR_NRST. We still get these error message after power cycling and load the image during uniflash.

    Any idea?

    Hello,
    I suggest you try to attach using the emulator, to make sure the JTAG to ARM is working. Then expand this to include the Control UART.

    You may then need to open a terminal on the PC for XDS110-debug com port to send data from the terminal,
    then using CCS (look at mmwave SDK driver UART to see if you can program the UART over CCS, and see receive data in the buffer.

    I don't have an example to send you.

    Hi Joe,
    We tried you suggest and this is what we get:
    An error occurred while hard opening the controller.

    -----[An error has occurred and this utility has aborted]--------------------

    This error is generated by TI's USCIF driver or utilities.

    The value is '-267' (0xfffffef5).
    The title is 'SC_ERR_XDS110_TARGET_SUPPLY'.

    The explanation is:
    The controller could not detect valid target supply. Check target
    JTAG connection and/or connection setting specifying voltage level.

    [End: Texas Instruments XDS110 USB Debug Probe_0]


    Any idea?

    Thanks!

    This seems to indicate that the XDS110 Debug Probe does not have 3.3v power. Please check that if you need it from the board, or a jumper configuration. You can also post this to the emulation team, as this is a problem with the XDS110 Debug probe.

    Hi Joe,
    Thanks for the help. Which 3.3V that you are talking about, IWR1443 board has its own power, how do we connect 3.3V to the debug probe. the JTAG Vref need to be connected to where on IWR1443 board? if it is okay to leave Vref open?

    Thanks,

    Hello
    Section 3, in the www.ti.com/.../sprui94.pdf, discusses powering the XDS110 probe. You have a choice of EVM power, 3.3v
    install R130, and connect to MCU_3v3, J6-1. You can use an external 3.3v power supply, just tie the power supply GND to the EVM GND.

    Thanks Joe! After connecting VTREF to +3.3VD from IWR1443, we are able to flash through the debug probe. Is it okay to this 3.3V from IWr1443?

    Thanks,

    Hello,
    3.3v power is about 60ma, for TVIA XDS110 it is OK for EVM, and LP87524 PMIC.
