Subject: kexec on kirkwood kernels?
Date: Wed, 26 Jan 2011 22:00:24 -0500 [thread overview]
Message-ID: <20110127030024.GF19307@localhost> (raw)
Has anyone successfully used kexec to boot one kirkwood kernel from
another? I've been trying to do it on a Seagate DockStar, but
all I see is this:
# kexec -l --append="console=ttyS0,115200" zImage
# kexec -e
[ 35.553632] Starting new kernel
Uncompressing Linux... done, booting the kernel.
and then nothing. I've tried with both 2.6.35 and 2.6.38-rc1 kernels.
I've tried modifying the kernel image to set the machine ID
explicitly, but that makes no difference. I wonder if the boot
parameters are being passed correctly, but I don't know how to check
without any console output. I do have a JTAG setup, but so far I've
only used it cookbook-fashion to re-flash the u-boot NAND partition.
I'm hoping someone can help me avoid having to use gdb over JTAG to
resolve this. Thanks.
