Hello Booters,
I am having some strange problems with "gd" on PXA255. Basically, I
am
experiencing intermittent memory corruption (e.g. a reported RAM size
of
3955MB) and the like. DECLARE_GLOBAL_DATA_PTR is defined as:
#define DECLARE_GLOBAL_DATA_PTR register volatile gd_t *gd asm
("r8")
on ARM platforms. I guess the question is then - what is supposed to
be
in r8, and where is this supposed to be set up? It looks like the
setup
for "gd" is simply incorrect for my platform, but I am not sure how it supposed to be.
Please advise.
Thanks in advance, craig vanderborgh voxware incorporated
