As of now this is not supported in crash. Well, in that case, it's not so much an endian-ness issue as it is a matching architecture issue. There is/was a sourceforge project that attempted to handle that: http://sourceforge.net/projects/crosscrash/files But it looks kind of dead... > I did start looking at the code, trying to understand how we read the data. > But before I jump in further I thought I would check if this is something > that has been tried in the past ?

The best that the crash utility can do is this: - run a 32-bit x86 crash binary on an x86_64 - run a cross-compiled 32-bit ARM crash binary on an x86 - run a cross-compiled 32-bit ARM crash binary on an x86_64 And the only reason that ARM-on-x86[_64] works is because they are both little-endian.
