Subject: kernel ported from ELDK 3.0 hangs (loops in idled()) on my custom MPC870 Board
Date: Fri, 3 Jun 2005 17:10:51 -0600 [thread overview]
Message-ID: <21fb73bc05060316102325f94d@mail.gmail.com> (raw)
I am trying to bring up Linux on a custom MPC870 Board using ELDK 3.0.=20
The ported kernel from ELDK 3.0 hangs (loops in idled()) and the kernel_thr=
ead=20
init never gets started!???
The board boots with the following messages:
