Re: Can not get "new" MPC8313e-RDB to boot "as-shipped" flash image

["Eric Cottrell" <wb1hbu@runbox.com>]

Hello,

Thanks for the help.  I will look into that.  It is confusing as the latest=
 ltib appears not to have the aliases.  This is my first venture into Embed=
ded Linux as our existing PowerPC products use PSOS.  Most of my Linux expe=
rience is on the Intel PC platform.

Yes, the 1.3.3 version was what was shipped with the board.  The rootfs and=
 kernel appear to be older.  So I suspect someone upgraded the uBoot and ra=
n into trouble.

I am comparing this with the Rev B board we also got.  I hope to return the=
 Rev A4 and make the boards all Rev B because it has a later processor.  Th=
e Rev B boards have 1.3.0 so it should need the aliases as well.  Looking i=
n the uBoot changelogs there are some nice additions and fixes for this boa=
rd so I will look to dig more into uBoot and upgrade it.  I hate to stumble=
 out of the box.

73 Eric
