I have. Did not work for me. The code I used was slightly updated over that from Lauterbach, and much of what was in that script and config package was just the publishable part of what Lauterbach provided. This was a very long time ago and for much older releases of software. So far as I know this was never updated, and the provided scripts were incomplete.
That part for which I did have success disappointed me. Whenever I went to debug something crashing in the kernel, the Trace32 also crashed. It was a lot of work to add something which provided no extra information.
Long ago I had asked about OpenOCD, and the gist was that the engineers had tried, but could not make it work. This of course would have depended on the particular hardware used, but I had also tried with an OpenOCD debugger and had even less success. If there has been progress since then I would also be interested, but I have not heard of any success other than with what NVIDIA uses in its internal tools (and I’m talking much much more expensive custom tools).
I would be in favor of any support of OpenOCD which NVIDIA might add. This would definitely bring a new level of support, but this is also extraordinarily difficult/non-trivial to do.
