As of 3-10-05, the Lab has been upgraded to include several Pentium 3 targets. These targets are currently placed in rtesp_7 to rtesp_12 locations. You will notice that a "p3" follows the name of the pentium 3 targets to remind you that these targets are Pentium 3 and not pentium targets.
If you try to download code built for Pentium targets to the Pentium 3's Tornado will give you an error stating that the code you are downloading does not match the processor type you are attempting to download to. In most cases, this could probably be ignored, but to get rid of the error, you simply need to add a new build specification to your project. This can be done by going to Project->Add/Include->Build and selecting the Pentium 3 build (see pic below.)
When using the connect2tgt.bat file to start target servers, you do not need to add the "p3" to the target you would like to start, the batch file will do this for you automatically.
Other than this, you should notice no difference with the Tornado 2.2 tools. If you have any problems please let me know ASAP.
