TMS320F28034: Error connecting to the target: (Error -1015 @ 0x0)

Part Number: TMS320F28034

Hi expert,

    My customer is using TMS320F28034 now. But there was an error of Error -1015 when downloading the code. The customer has already tested the wait BOOT mode by referring to the following link and picture 1. However, it shows that the connection is still unsuccessful, and the password value cannot be monitored, as shown in picture 2. The program cannot run after power-on. Could it be the internal damage of the chip?

    Julia,

    If the customer can't connect via the wait boot mode, I would give the following suggestions:

    1)When they connect to the device, make sure to launch the target configuration file (.ccxml) manually by right clicking on it and "Launch Selected Config".  Then connect to the device by right clicking on the C28x CPU and "connect".  I want to make sure they are not using the "debug" button to try to connect if the device is in a locked state.

    2)If the above doesn't work, can customer check the following:

    a)Is the device hot to the touch?  This would indicate that there has been some electrical damage(short)

    b)Can customer use DMM to measure the 3.3V and 1.8V supply(even if they are using the internal VREG).  If these are not in spec that could be another indication of either damage to the device or to the external LDO

    c)Using an o-scope look at the XRSn pin.  Do they observe a steady state, or toggling signal.

    We can discuss next steps once customer does the above.

    Best,

    Matthew

    Hi Matthew,

    After testing by the customer, it was found that an electrical shock of about 5V occasionally occurred at the moment of power-on, which may damage the chip. I think this may be the cause of the problem. Thank you very much for your support!
