Oh this is not the case, I think you may have misunderstood me. I use
Flyswatter2 and OpenOCD all the time with Zynqs and soon BBBs.
I said it was not working because debugging via JTAG takes some effort to set up

the am335x processor. If you 'reset halt' in OpenOCD you have around 6 seconds
to get things sorted or the watchdog will trigger. I received excellent support

I have RTEMS applications loading and running over JTAG and I am now look into
cache related issues that is effecting breakpoints, stepping etc.
I am starting to update our Wiki to document all this...
