I have a BeagleBoard-xM and have created a custom system based on:
I've successfully booted to a prompt, I've written up all the steps I
However, when I try to specify a newer gcc version in crosstool-ng I
get a kernel panic when init is started.
If I've understood correctly, gcc-4.3.2 does not allow armv7-a (cortex-
A8) to be specified as an architecture level. The BB-xM is a DM3730,
which is a cortex-A8 core. Therefore, I've tried with gcc-4.4.5 (the
highest non-experimental version of gcc available in crosstool-ng).
Unfortunately, with this gcc version, the kernel panics.
My questions are:
- Has anyone got a BB-xM booted with armv7-a/cortex-a8x specified as
the gcc architecture level with hardware FPU enabled? If so, what have
- Can anyone suggest alternative toolchain & root filing systems tools
(other than openembedded)?
I've tried all sorts of combinations of settings with crosstool-ng and
buildroot, but without success. My only theory so far is a problem
with glibc; as far as I know, neither u-Boot or the kernel are
dependent on it so the system can boot until init is called.
