[Redbutton-devel] Problems running on arm platform...

[Stuart H. <st...@li...>]

Hi,
   I've been trying to get rb-download to work on an arm platform 
(Sheevaplug) but it's having some trouble decoding the data. The 
standard error message I get is:

Expecting BIOP::ObjectLocation

However after some hacking around with the C code it looks like a 
conversion problem in biop_uint32. Some details below:

The conversion error appears to be:

49530002 - 49534F50

where the first value is the converted result, and the last value is 
what it expects. You can see that in the hex dump above that value is 
there, and the same goes for the DSM::ConnBinder value later on (if I 
override the fatal error).

I'm pretty rubbish at C, but i'm hoping someone on the devel list can 
shed some insight, or possibly a patch, to fix this :-) I'm willing to 
test any patches that people can provide etc.

Regards

Stuart
