Comment (by nick.withers):

 Replying to [comment:6 nick.withers]:
 > I seem to have problems with my toolset and can't even get current-
 source-builder-built GDB to talk to my BDI-3000.

 > It looks like SPE might be getting enabled (e.g., *trying* to boot gives
 "Welcome to rtems-4.10.99.0(PowerPC/Generic (E500/float-
 gprs/SPE)/mvme3100)"), so I'm trying to figure out whether the previous
 GCC 4.9.2 patches definitely made it in to 4.9.3 (would that explain GDB
 not being able to talk to the BDI though?!).

 The patches did indeed make it in.

 4.9.3 GDB works fine talking to my BDI - but only if it's not given the
 (presumably incorrectly-SPE-enabled) binary.

 Any ideas?
