Hello Juergen,
I had this question posted in the ptxdist mailing list. Re-posting here for
proper context.
Previous message:
Currently, I still have kernel panic messages when building the rootfs
using Pengutronix and CodeSourcery. It seems perhaps that it is
because of gcc 4.5.1 that is being used in my version of CodeSourcery.
When I use your OSELOS toolchain, I can burn an image properly and do not
receive kernel panic messages. Your toolchain uses gcc 4.5.2.
Last message:
I am wondering if you would be able to help me with kernel panic issue? I
have tried different gcc versions of CodeSourcery with about three kernel
versions and I always get kernel panics when booting mini2440. I am
following your quick start guide for either botting from nfs or nand. I
follow the procedure for nand updates etc. Is there an inherent problem
with burning JFFS2 format on mini2440 or is it Code Sourcery that perhaps
has a problem? Any help would be much appreciated. Please let me know
what information I need to provide for you to be able to help me?
