I'm trying to do the bring-up for our board and I'm afraid I'm stumped.
I can see the board in the Control Center and I can attempt to load a program to RAM, but then it fails to enumerate again. So I tried to debug the code.
I'm having pretty much the same symptons as this old post:
[FX3 Debug] Error: can't add breakpoint: target running
... but I can't move forward.
Here's my console dump:

But I can't debug, execution doesn't stop at main, arm-none-eabi-gdb is terminated (exit value 0) as does openocd.exe (exit value 1). We have an on board CY7C65215-32LTXIT and it's both wired and programmed exactly as the one in the Explorer Board. Still, I can't debug (but I have no problems whatsoever in the Explorer Board).
Since I also have the "target not halted" I checked the schematic and even measured connectivity for TRST and everything seems to be sound. I don't have an oscilloscope at hand*, so I wanted to see if there's something else I could test.
Any ideas?
Even if it's just a JTAG problem, I'm still at a loss as to why it wouldn't enumerate. I made a small app that does nothing beyond basic clock config and RTOS start, and it still doesn't enumerate.
* As I write this, I'm suspecting the error on "Error: JTAG scan chain interrogation failed: all ones".
