There are a number of users on this mailing list who have tried to get openocd working with BBB, but I¹m not aware of anyone doing this successfully. I know these users spent weeks working on this and if you consider the opportunity costs, the USB100V2 at $100 is much more cost effective and it just works. Also note, that with CCSV6, you don¹t get a Linux aware debugger so you are limited in the things you can do. You get source level debugging and you can set hardware breakpoints, but you don¹t get tracing and don¹t think about debugging kernel modules because that requires you to understand how Linux loads kernel modules. Also, CCSV6 isn¹t thread aware so when you are single stepping, the scheduler might switch switch threads on you and that adds another level of complications. I use Lauterbach which is Linux kernel aware and this make life much easier. It is possible to use CCSV6 for Linux Kernel debugging, but just be aware of the limitations.
