Toolchain built and helloworld app compiled. Not sure if you intended for the name of the sample to be prefixed 'aarch' instead of 'arch': aarch64-rpi3-linux-gnueabi/ Output of `file helloworld`: helloworld: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 4.0.4, not stripped Built on 64-bit Debian Jessie. Of course helloworld won't run on my Pi3 with 32-bit Raspbian. Did you intend this sample to not be hard-float? (I don't know whether the Cortex A53 is HF or not). There is some debate on the Foundation site whether running 64-bit with only 1GB of RAM is much of a gain but it will be interesting finding out. Foundation forum mods and developers haven't mentioned whether boot-loader needs to be 64-bit as well. Mike -- Michael A.

It’s “arm arch 64” ;) They also call arm 32-bit aarch32, but config.sub still search for arm* instead of aarch32. > > Output of `file helloworld`: > > helloworld: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), > dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for > GNU/Linux 4.0.4, not stripped Looks good! > > Built on 64-bit Debian Jessie. > > Of course helloworld won't run on my Pi3 with 32-bit Raspbian.

I have no idea whether the boot-loader is bitness-independent or not, but I found no suggestion it isn't. I don't know much about the finer points of architectures but I will give a kernel compile a go (when I have recreated the toolchain with HF) just for the hell of it. It'll probably crash and burn.

In common with other 64-it systems, like x86 for example, to run a 64-bit application you need a 64-bit operating system, and to run a 64-bit operating system you need a 64-bit boot-loader. The privilege levels in the system only support running 64-bit at one privilege level if the level above it is running at 64-bit; and you can only switch states as you enter a privilege level, so if your top-level boot code isn't 64-bit you'll never be able to get back to that state.
