Well you said armv4t thats a whole different story than armv4 (without 't') for EABI AFAICT SA1110 is based on ARMv4 not ARMv4t. > > Thanks, > > TAS > > > > _______________________________________________ > Openembedded-devel mailing list > [email protected] > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel > _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
