CC2652R: Device is Locked

Part Number: CC2652R
Other Parts Discussed in Thread: LAUNCHXL-CC26X2R1, , UNIFLASH

Hi,

When I was working on my CC26X2R1 Launchpad, the board reported "security error" with "make sure device is unlocked". I searched the forum, and tried to use Flash Programmer 2 to perform "Mass Erase" to unlock it following link https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/918427/ccs-cc2652r-error-code--241-a-router-subpath-could-not-be-accessed-a-security-error-has-probably-occurred-make-sure-your-device-is-unlocked, but the device couldn't be recovered although it shows Mass Erase succeeded:

And I tried to use CCS to debug on board after mass erase, it shows different error now:

"Error initializing emulator:
(Error -260 @ 0x0)
An attempt to connect to the XDS110 failed.
The cause may be one or more of: no XDS110 is connected, invalid
firmware update, invalid XDS110 serial number, or faulty USB
cable. The firmware and serial number may be updated using the
xdsdfu utility found in the .../ccs_base/common/uscif/xds110
directory of your installation. View the XDS110SupportReadMe.pdf
file there for instructions.
(Emulation package 9.5.0.00143)"

I also tried to perform "Test Connection" from "Target Configuration" Review, it reports below logs:

[Start: Texas Instruments XDS110 USB Debug Probe]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

Is there any other way to save my board?

Any help will be appreciated!

Thanks,

    Hi Xiaofeng,

    These errors are typically due to an unstable XDS110 debugger connection.  Are you programming the CC2652R device on the LAUNCHXL-CC26X2R1 board or using the LaunchPad's XDS110 to program a separate PCB?  Are you using the USB cable which came with the EVM?  Do you have multiple LaunchPads to test with?

    Regards,
    Ryan

    Hi Ryan,

    Thanks for your reply!.

    Yes, I'm working on the LAUNCHXL-CC26X2R1 board now, and have been already working on this board for 2 months, the XDS110 is directly with USB cable. When this issue happened, there was only on Board connected. I also tested another board with same USB cable, it's working fine.

    Best,

    Xiaofeng

    Thanks for the update.  The XDS110 debugger appears to be unresponsive, perhaps you could find more from the User Guide or Documents page.  Is the LED indicator green on the XDS110 side of the board when plugged in?  Are there any noticeable differences between the LaunchPads being tested (jumpers, hardware version, etc)?  Could the board have been exposed to ESD or excessive voltages?

    Regards,
    Ryan

    The LED is always showing green, and 3.3V voltage is connected as external power supply. It was working fine before the issue occurred. I also tried to restore the default jumper connections with USB only, but no lucks. Looks like something is wrong on the board.

    Have you tried programming with Uniflash or Flash Programmer 2, or reducing the JTAG clock speed in CCS from the target configuration file?

    Hi Ryan,

    Yes, I tried both UniFlash and Flash Programmer 2, none of them is working.

    I also tried the different Clock from 100K to 5M for JTAG, no lucks for me.

    Thanks,

    The tests show that the XDS110 appears to be inaccessible.  You can attempt to contact TI Customer Support for a replacement, be sure to provide this E2E thread and your invoice/order number in the request.  It is still possible to program the on-board CC2652R1 using an external debugger connection.
