You have to build an armeb toolchain with armeb as the platform in the tuple. I don't see one on mentorgraphic's site.

Yes, the toolchain output's xscale optimized binaries and is configured for big-endian. For autoconf based projects, it actually checks the platform part of the tuple to figure out if it is little (arm) or big endian (armeb). I'd prefer just using the -EL or -EB flags on arm-unknown-linux-gnueabi, but as I said before, I'm not sure if you can build a multilib arm/armeb toolchain. > Best regards, > Marek Vasut ^ permalink raw reply [flat|nested] 12+ messages in thread
