However, after loading the symbols (add-symbol-file vmlinux), I get this error message:&lt;/p&gt;
&lt;p&gt;WARNING(ROS60): Could not enable OS support as the OS does not appear to be initialized. This might be caused by a mismatch between the loaded symbols and the code on the target or because the OS is not up and running. Enabling OS support will be re-attempted when the target next stops.&lt;/p&gt;
&lt;p&gt;Note that kernel debugging works fine with Linux 4.19-rt. I&amp;#39;m using Arm Development Studio 2020.0 (Intel FPGA Version) and debugging a Cyclone V SoC using an Altera USB-Blaster II, if that&amp;#39;s of any interest.&lt;/p&gt;
&lt;p&gt;Can anyone tell me what&amp;#39;s the limit here? Why does it work for 4.19, but not for 5.4?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thanks,&lt;/p&gt;
&lt;p&gt;Simon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Ask A Question I</title><link>https://community.arm.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09</link><pubDate>Tue, 15 Sep 2020 18:18:35 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:eeb25242-2199-497a-a3a5-cd0d790d091b</guid><dc:creator /><description>Ask a question in a forum.</description></item></channel></rss>
