Compiler/CC3235S: attaching board to usb debugger

Part Number: CC3235S

Tool/software: TI C/C++ Compiler

Team, 

My customer is having an issue attaching their development board via the usb debugger: 

I am getting an error message in the IDE.

 Error connecting to the target:

(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.2.0.00002)

Can you please provide some guidance. 

Thanks

Viktorija

    Hi Viktorija,

    Is this a launchpad or custom board? The most common reason for this is because the device has been flashed with a production image, which locks the JTAG. Please ask the customer to make sure they flash their device into development mode before trying to debug.

    If that does not work, and it's a custom  board, lets review the schematic and make sure we are connecting to the device correctly. 

    BR,

    Vince
