Hi, Michael and I (well, mostly Michael) have been working on porting the LM32 JTAG debugger to Spartan6 and Milkymist SoC. Hopefully this could help troubleshooting the instability issue.
Unfortunately we are facing timing problems when debugging is enabled in the complete SoC. Right now, we can meet timing with a reduced version of the SoC in these conditions: * ISE 12.2 * edit common.mak and pass the -t 60 flag to MAP * edit the system.xst file and set -lc off * edit setup.v and disable everything except USB * you'll need to remove placement constraints in xst.ucf for the components that were disabled in setup.v (I'll try modifying the code so this step isn't necessary anymore...) Fortunately, this still gives us a workable environment for debugging the current Flickernoise problem.
