<div dir="ltr"><div dir="ltr">Hi Rotem,<div><br></div><div>We have started to try to capture information to help make migration easier. See <a href="https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/user/migration/v4_11-to-v5.html">https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/user/migration/v4_11-to-v5.html</a> for the migration from 4.11 to 5. That may help you some.</div><div><br></div><div>In addition, the configuration options are documented at <a href="https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/c-user/config/index.html">https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/c-user/config/index.html</a></div><div><br></div><div>Usually, you should check your configuration when migrating and also look for deprecated/obsolete APIs in use. (And, if you broke the API visibility somehow, you may need to fix that on your end. Some users like to "peek under the sheets" to see what is going on in RTEMS source, and then make application code that is implementation-dependent. This is not recommended in general.)</div></div><div><br></div><div>In your specific case, you should check out <a href="https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/c-user/config/general.html#configure-unified-work-areas">https://ftp.rtems.org/pub/rtems/releases/5/5.1/docs/html/c-user/config/general.html#configure-unified-work-areas</a> maybe as a start</div><div><br></div><div>Gedare</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jan 3, 2021 at 5:21 AM Rotem Dror MTH <<a href="mailto:rodror@iai.co.il">rodror@iai.co.il</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
