TMS320F28069: XDS560v2 can not access to F28069 after a reset occurred during flash programming

Part Number: TMS320F28069

Hi Champs,

A customer has been facing a trouble as follows:

An external HW reset occurred during flash programming with XDS560v2.
After that, CCS shows the error message below and it never connect to the board.

Error connecting to the target:
(Error - 180 @ 0x0)
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.
(Emulation package 6.0.407.3)

The voltage between VTREF and GND on JTAG is approx. 3.295V.
Has there been any known issue?
I would like to know what the customer should check and do for its recovery.

Thank you for your kind check.
Best regards,
Hitoshi

    Hi Hitoshi,

    Are they using a custom board or a TI evaluation board? Is the 'Test Connection' feature within CCS successful for them?

    There's a good Application Report on JTAG connectivity debugging, linked below:

    http://www.ti.com/lit/spracf0

    What are the state of the boot mode pins on the customer's device?

    Best,

    Kevin

    Hitoshi,

    Seeing if this is still an issue or customer has understood the issue.  Please let us know if there is more action required from us.

    Hi Matthew,

    They are utilizing their custom board.
    After they clicked "Test Connection", the log was as follows:

    [End: Texas Instruments XDS2xx USB Debug Probe_0]

    Pin conditions:
    GPIO37/TDO:  1,  GPIO34: 1, TRST : 0    --> MODE 3 GetMode


    According to the customer, when a reset occurs during flash programming, they have heard that  the access is denied with some devices because of the security.
    With this case, does the device get into the security mode?
    Or is the flash collapsed? 

    Thank you for your kind check.
    Best regards,
    Hitoshi

    Hi Hitoshi,

    Are they able to connect when TRST is set to 1 for emulation boot mode?

    Are the CSM passwords getting programmed and locking the device when this occurs? Address for CSM passwords is 0x3F 7FF8.

    HI Kevin,

    The device has been returned to TI for test.
    It would be treated by our quality team.

    Please close this thread.
    Thank you for your kind advice.

    Best regards,
    Hitoshi
