I found if I set breakpoints in assembly code, the DS-5 debugger is not trapped there on omap3530 beagleboard. In addition, it doesn't step in assembly codes, if assembly codes are in a static/dynamic libs.

The DS-5 releases are tested on various versions of Windows and Linux both 32- and 64-bit.
For Linux hosts, the primary platform is Red Hat Linux Enterprise 5 for x86 (32- & 64-bit). They have also been tested some on Ubuntu 9.10 64-bit, but it's not officially supported yet.
I tested DS-5 in Windows Vista, there are still no frame stacks in assembly codes except registers view.
