I have an application that I'm writing on a little endian x86 system, but I would like to test it on a big endian processor to ensure compatibility. I understand that the ARM processor can go big endian or little endian, but by default the Raspberry Pi is little endian. Is there a big endian distribution/operating system available? If not, what am I looking at to construct one? Is it possible with the Raspberry Pi?

Thanks!

There's an Endianness option in Target Options, you may select and change when building a new kernel for your device. I haven't tried it myself, but it just might work.

Unfortunately, I don't know of any precompiled big-endian distributions for ARM. However, there's an article "Building a Big Endian ARM Cross Compiler Toolchain", a bit outdated, but still useful.

I have built a big endian tool chain, a big endian kernel using buildroot to no avail. Something tells me that the bootloader must set the processor in big endian mode before it jumps to the kernel, but the bootloaders are closed. Maybe its not a bad idea to consider uboot...
