Target request failed: Failed to step, An error occurred while trying to Step in target.

Hi All,

I ported the BSP from K60F120M to my target board. I want to try the UART communication using MQX RTOS.

But when I try to debug it, it always gives me lost connection  error.

When I try to step in it and find which part cause this problem, at first step(when try to disable interrupt and clear flags), it gives me error:

"Target request failed: Failed to step, An error occurred while trying to Step in target."

I checked my debugger setting, it is already set to disable interrupt when stepping.

Any advices will be appreciated.

Thank you.

I figure it out. Because the ttya in the library is mapped to PTA1 and PTA2 which are also used for JTAG on my board.

I need to reconfigure the pin for it and it works.
