Prodigy 20 points
Part Number: TMS570LC4357-EP
Other Parts Discussed in Thread: TMDSEMU200-U

We are using TMS570LC4357-EP micro controller and for programming we use  XDS200 DEBUG PROBE TMDSEMU200-U .  The JTAG is Detected but when we try to flash the Code it's showing Error Like:

Error connecting to the target:

(error-1170@0x0)

Unable to acces the DAP, Reset the device, and retry the operation, If error persists, confirm configuration, power-cycle the board, and/or try more reliable Jtag setttings(e.g. lower TCLK)

(EMULATION PACKAGE 9.12.0.00150)

is anyone Help to Clear the this Error?

    Hi Karthik,

    Error-1170: This is usually caused by either a hardware failure on the board or invalid code on the MCU flash that causes it to reset itself continuously. Have you programmed any code to the flash before? If it is caused by the invalid code, please try this procedure to let CPU enter a debug state:

    1. Open the target configuration window, and launch the selected the configuration
    2. Switch to debug window.
    3. Press the reset (nRST) button and hold it.
    4. Click “Connect Target” immediately after you release the nRST button.
    5. The board should be connected after couple tries.
