As I said off-list, I don't know if there's a list of GDB BSPs, but I<br>
know of at least:<br>
powerpc/psim<br>
mips/jmr3904<br>
moxie/moxiesim<br>
arm/gdbarmsim<br>
sh/shsim<br></blockquote><div><br></div><div>I consider psim and jmr3904 to be top tier BSPs even though they are simulators.</div><div>jmr3904 has more failures but that's because some support like TLS is missing</div><div>on the MIPS.</div><div><br></div><div>moxiesim and shsim (multiple variants there) should work but I don't recall. </div><div><br></div><div>I would like to remove gdbarmsim.

I have no idea what any of their statuses are or if they are expected<br>
to work. The first step would be building them and see if they run<br>
anything. After that, you should look at the existing tester scripts for<br>
some targets:<br>
rtems-tools.git/tester/rtems/testing/bsps<br>
I see scripts for most of what I listed above, so the next step would<br>
be trying to run them via tester and see if it works.<br>
<br>
BTW: Did I mention adding these to tester, or did I mention creating<br>
build sets for them? Anyway, I think the GDB simulator builds by<br>
default with the toolchain, so there is no difference between a BSP<br>
buildset (such as for jmr3904) and one that supports running on GDB.<br>
At least, I think so. It is worth verifying.<br>
