Hi guys,
I'm trying to boot FreeBSD over Pandaboard for one of my projects, but I'm stuck with an issue that it's blocking me and
I'd like to see if someone can provide some insight.
My setup goes as it follows:
============================
- Pandaboard with SD card.
- SD card correctly formated:
First partition:
o U-Boot
o MLO
o FreeBSD kernel image
- FreeBSD kernel image was built from:
o SVN Revision: 248896
o Using: make buildkernel TARGET_ARCH=arm CPUTYPE=armv6 KERNCONF=PANDABOARD -j5 -DCLANG_IS_CC=no
- U-Boot and MLO were built from:
o origin: git://git.linaro.org/boot/u-boot-linaro-stable.git
o Commit ID: 30dd996a40c7673258bd5743c0813230d92abc7c
The problem is the following:
=============================
When Pandaboard is reseted I stop the autoboot and try to load the kernel image from tftpboot, which succeeds. However, when I
try to run it in the address where it's loaded, it panics right at the beginning of the kernel boot.
I also tried booting the kernel from the SD card, with identical result. Also with different versions from the source tree,
and I always get the same panic in the same place.
Am I doing something wrong? Maybe somebody can give me a hand.
Here are some logs of what I see:
=================================
