I was trying to debug a page fault problem with watch exceptions
since these exceptions (lower priority) come after the page fault
and sometime it will also get deferred till ERL and EXL bits are
cleared hence in this specific case they aren't helping me.
other option can be to take support of EJTAG debug available on
meanwhile i have noticed and simply tried to read the value and
something on few userspace addresses(0x0 - 0x7fff_ffff) from my
kernel and surprisingly it just hangs..ideally from my kernel i
should be able to access all these addresses .
further VXWORKS port run fine on same piece of hardware ..does it
looks like some mem bank configuration problem in my bootrom , or
it may be a matter of chance because of its specific
any suggestions ..
