Hello Jan,
cool progress! Looking forward to test once things settles a bit,
although I'm more of thumb person in arm world. :-)
Thanks for sharing!

Hi everyone,
Sorry for the delayed response.
Yes, that’s me. I am responsible for the RTEMS related work-package in
the “cRustacea in Space” project.
One of the goals is to create a prototypical port of Rust to RTEMS for
our example target platform (Xilinx Zynq).
The status is currently the following:
* I have a custom target based added to the compiler sources
which compiles Rust code for the Zynq
* I ported the stdlib to work with RTEMS (using the POSIX API)
* I ported the libc wrapper for this to work
* I can now compile the below application and unit test and run
it on the (simulated) target using cargo build/run/test without the
need to use any extra attributes as a work-around.
fn add_two_numbers(num1: i32, num2: i32) -> i32 {
num1 + num2
}
#[test]
fn test_add_two_numbers() {
assert_eq!(add_two_numbers(2, 3), 5);
}
pub fn main() -> ! {
println!("Hallo from println");
println!("2 + 2 = {}", add_two_numbers(2,2));
loop {}
}
My next goal is to add those changes to the official Rust repos in
order to have it as a Tier3 target platform.
I need to tidy up my commits and have a few open questions regarding
naming conventions (I will start a corresponding thread here shortly).
With that done, it should be much easier for others to play around
with Rust on RTEMS as it only requires to install the nightly compiler
via rustup.
Cheers,
Jan
