I am working with the F28M35H52C1 RevB board, and CCS 6.
I have been setting hardware breakpoints on the M3. The breakpoint works, but when I remove the breakpoint, the core still halts at that code location. The breakpoint indicator is gone, the right click context menu shows as if there is no breakpoint, and I have even tried turning on "Skip all breakpoints". Yet the code continually halts at that location. I have to unplug the power and JTAG connections to restore proper operation.
On a possibly unrelated note: I also cannot set breakpoints on the M3 unless I pause the core first. I can do so on the C28 just fine.
