Hello<br><br>I&#39;m
trying to get kgdb working on a mpc8540 based target machine. I took
the latest patches which are for 2.6.13(mine is 2.6.11) and build and
made changes to config by enabling :<br>
- Compile the kernel with debug info<br>- KGDB: kernel debugging with remote gdb <br>- KGDB: Console messages through gdb<br>- Method for KGDB communication (KGDB: On ethernet - in kernel)<br><br>I also added bootargs through uboot as:<br>


kgdboe=<a href="http://6443@10.110.1.2/,6442@10.110.1.31/00:0F:1F:6E:F3:30" target="_blank">6443@10.110.1.2/,6442@10.110.1.31/00:0F:1F:6E:F3:30</a> kgdbwait<br><br>Now, I&#39;m getting the messages:<br>netconsole: not configured, aborting<br>


kgdboe: eth0 doesn&#39;t support polling, aborting.<br>kgdboe: netpoll_setup failed kgdboe failed<br>&nbsp;<br>And after some lines;<br><br>kgdb: Defering I/O setup to kernel module.<br>kgdb: Waiting for connection from remote gdb...<br>


But then it goes to load ramdisk.<br><br>Can someone please provide some help on this<br><br>thanks<br><br><br>
