Tool/software: Code Composer Studio
I just got a new MSP432401R launchpad. It asked to update the XDS110 the first time I programmed it, so I assume that it is up to date.
I can re-program the gpio_toggle_output example just fine. But when I run the timer_32periodic_mode_led_toggle example (code below), it programs fine the first time, but any subsequent re-programs give me the following error:
CS_DAP_0: Error connecting to the target: (Error -614 @ 0x0) The target indicates there is an error condition from a previous SWD request.
Clear the error the condition, and try the SWD request again. (Emulation package 7.0.188.0)
And I can only cancel. Once I pull the USB and put it back in, everything is fine.
I thought it might be the fact that it is in LPM0 mode, so I commented that out of the while loop, but still had the same problem. Any thoughts?
