The v8 Foundation Model User Guide has a bare metal hello world example that uses semi-hosting. The Makefile uses ARM tools, however. Is there equivalent support for this example using a bare metal version of the gnu tools, such as gcc-linaro-aarch64-none-elf-4.8-2013.04-20130422_linux.tar.xz? I took a look, but didn't see a way to do this.
Of course, running the Linaro linux port on the v8 Foundation Model allows one to run hello world and much more, but I'm currently only interested in a bare metal target using gnu tools.
Thanks, Don

It is possible but not necessarily easy.
Using the binary tools you've downloaded you will want to do something like the following:
aarch64-none-elf-gcc -specs=elf-aem-ve.specs ...
The -specs option has to be on all your invocations of GCC and G++. You should also invoke the linker through GCC with this option.
Then you need to invoke the model, given an image called foo.axf:
Foundation_v8 --image foo.axf --semi-host="foo.axf OPT1 OPT2" --quiet
Note that the first option to --semi-host is the name of the image again.
Thanks,
Matt
I was able to track down the specs file you mentioned and get the hello world example to work. Thank you!

I had been meaning to mention this. Is there some way you could include the AEM specs file in the next toolchain binaries release, either by using a newer snapshot of the Newlib repository or back-porting the file to the version (last release?) currently used?
Thanks, Christopher
