AVR32 init segfault: Any resolution?

AVR32 init segfault: Any resolution?

[Geoffrey Wossum]

Hi all,

With Richard's help on the toolchain and a patch to the 
conf/machine/at32stk1000.conf (submitted via Bugzilla), I can now boot the 
kernel on my AVR32 based AT32STK1000.

However, init segfaults.  Here's the last boot of the boot activity before the 
segfault:

Waiting 1sec before mounting root device...
mmc0: new SD card at address b368
mmcblk0: mmc0:b368 5     249856KiB
 mmcblk0: p1
VFS: Mounted root (ext2 filesystem).
Freeing init memory: 64K (90000000 - 90010000)
init[1]: segfault at 00000008 pc 2aaabbe8 sp 7ffd0f20 ecr 24
init has generated signal 11 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!


Alex reported the same bug about a month ago to this mailing list.  I haven't 
seen any resolution to it, though.  Is there a resolution to this bug yet?


Thanks,

Geoffrey

You should be able to use busybox as init nowadays, or add add uclibc
0.9.29 for avr32 :)

Dear all

Put up on the below message i started a new toolchain and added
uclibc-0.9.29 as preffered in angstrom-2008.1.conf

I dont have the atmel toolchain on this box and the minimal-image ends
up like this:

NOTE: package uclibc-initial-0.9.29: started
NOTE: package uclibc-initial-0.9.29-r9: task do_configure: started
NOTE: exceptions.AttributeError:'module' object has no attribute
'get_srcrev' while evaluating:

| make: avr32-angstrom-linux-uclibc-gcc: Command not found

am i supposed to install the atmel toolchain and set them as
preferred_provider as this message says :

NOTE: multiple providers are available for
virtual/avr32-angstrom-linux-uclibc-libc-for-gcc (external-toolchain,
uclibc);
NOTE: consider defining
PREFERRED_PROVIDER_virtual/avr32-angstrom-linux-uclibc-libc-for-gcc


On my laptop i have both the atmel chain and "somehow" manage to get a
oe build up to minimal-image.



Regards Robert

Going to uClibc 0.9.29 fixed some of the weird build problems I was having, 
but I still get a segfault on init.

So how do I go about making busybox my init?
