During this regression test, I saw many failures are caused by "Cannot insert hardware breakpoint 8" and "You may have requested too many hardware breakpoints/watchpoints". It's true that my arm board only supports limited number breakpoints. So how to workaround this limitation for regression test? Thanks. BR, Terry
