Hi,
I am attempting to run the L4linux ARM build from the Fiasco + L4Re +
L4linux snapshot l4re-snapshot-2010111519.tar.bz2 but L4linux is kernel
panicking during startup. Here's my build information and a snippet of the
error output. I'd appreciate any help trying to figure out what's going
wrong and resolving the problem.
GCC_PATH_PREFIX=/opt/sourcery-g++-lite/bin/arm-none-linux-gnueabi-
L4ARCH=arm
make setup
-> selected ARM realview
make
cd obj/l4linux/arm-up
make arm_defconfig
make menuconfig
-> set L4 build path obj/l4/arm-rv
-> set cross compile prefix arm-none-linux-gnueabi-
-> turned on ARM EABI + old EABI binaries options
make
cd obj/l4/arm-rv
make image E="L4linux ARM"
qemu-arm-l4 images/bootstrap.elf
Got through to Ned: loading file: 'rom/l4lx.cfg' without any apparent
issues. L4linux started, but got a bunch of bad page errors:
BUG: Bad page state in process swapper pfn:0431c
page:00488380 count:4752264 mapcount:0 mapping:00488390 index:0x488390
page flags: 0x488380(slab|owner_priv_1|arch_1|tail|buddy|mlocked)
These went through, and then it looked like the kernel was proceeding, but
eventually:
l4lx_irq_init: creating IRQ thread on cpu 0
irq_thread: Starting IRQ thread on CPU 0
