<br>
This is a good question. These configuration changes need to be<br>
populated somehow based on the target being built. If this is only<br>
doable by writing files directly, then we'll probably need a way to<br>
apply patches for each different target. This seems unwieldy, so<br>
further thought should be considered on how to configure EPICS based<br>
on the RTEMS BSP build.<br>
<br>
You can start with a manually-created patch file, but eventually we<br>
need something that can be used across different BSPs / architectures.<br></blockquote><div><br></div>The manually-created patch file has worked. <br>Now, what can be done to make it work across different BSPs / architectures?<br>Will writing similar patches for each architecture should be our way?<br>And I guess in the #FHI section as well we have to do something so that user <br>can add the path interactively where the user's BSP are installed? <br>Would you like to give any other feedback/suggestions? <br><br></div><div class="gmail_quote">Thanks<br><div>Mritunjay </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
