TMS570LS0714: TMS570LS0714PGE

Part Number: TMS570LS0714


Hi， 

My code does not involve any complex functions such as encryption, JTAG protection, etc.

Then suddenly it can't be burned, and the microcontroller will run automatically when it is powered on.

Now there are three boards with this problem.。

When burning with XDS100V3, the problems reported are:

CortexR4: Trouble Removing Breakpoint with the Action "Remain Halted" at 0x80004c0: (Error -1066 @ 0x80004C0) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 7.0.188.0) 
CortexR4: File Loader: Memory write failed: Timed out waiting for target to halt while executing erasew.alg
CortexR4: GEL: File: D:\TM.out: Load failed.

Sometimes will be reported as follow when connecting .

 Error connecting to the target: (Error -241 @ 0x0) A router subpath could not be accessed. A security error has probably occurred.

Make sure your device is unlocked.(Emulation package 7.0.188.0) 

I also tried to connect with Lauterbach's simulator,and reported “access timeout，processor running”

 thanks

    Hello Zhiwei,

    You have programmed you code to the flash successfully before, right? The code may have an exception repeatedly. Please try this procedure:

    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

    Dear QJ Wang:
    Thank you for your response.

    But the problem has not been solved.
    And several chips have the same problem recently . Do you have any other way to unlock them?
    Or I can send the board to you.
    thank you.

    Error connecting to the target:
    (Error -241 @ 0x0)
    A router subpath could not be accessed.

    Make sure your device is unlocked.

    Hello Zhiwei,

    This device includes a an Advanced JTAG Security Module (AJSM) module. The AJSM provides security to the memory content of the device by letting users secure the device after programming. The device is unsecure by default, and you can secure it by programming the visible key located in OTP. Did you program the AJSM before for those devices?

    If you didn't program the AJSM, the device is unsecure and the JTAG is not locked.

    As I said, this is the right way to connect to the device through JTAG:
    1. Open the target configuration window, and launch the selected the configuration
    2. Switch to debug window
    3. Press the reset (nRST, not nPORRST) button and hold it
    4. Click “Connect Target” immediately after you release the nRST button
    5. The board should be connected after couple tries
