Other Parts Discussed in Thread: SEGGER

I'm having problems with the segger j-link and swd. Having trouble debugging, but now it started locking the flash in the device.

Is there info on how to unlock the flash so I can erase it ?

Hello Shawn

Please refer to the following application note on JTAG debug where the process to unlock the flash is provided. You would need an XDS100v2 to unlock the device

Thank you for the link.

However our problem is we've only implemented SWD. Do you know if there is a time frame for TI implementing the two wire SWD in CCS?

Hello Shawn,

You would need to check with Code Composer Studio Forum for SWD support in CCS as we do not develop the drivers for the same. even if SWD is implemented on board, the XDS100 probe can be blue wired to the board run the JTAG unlocks sequence.
