# *-kmc-solid_*

Tier: 3

SOLID embedded development platform by Kyoto Microcomputer Co., Ltd.

The target names follow this format: `$ARCH-kmc-solid_$KERNEL-$ABI`, where `$ARCH` specifies the target processor architecture, `$KERNEL` the base kernel, and `$ABI` the target ABI (optional). The following targets are currently defined:

Target name | `target_arch` | `target_vendor` | `target_os`
--- | --- | --- | ---
`aarch64-kmc-solid_asp3` | `aarch64` | `kmc` | `solid_asp3`
`armv7a-kmc-solid_asp3-eabi` | `arm` | `kmc` | `solid_asp3`
`armv7a-kmc-solid_asp3-eabihf` | `arm` | `kmc` | `solid_asp3`

## Requirements

This target is cross-compiled. A platform-provided C compiler toolchain is required, though it can be substituted by GNU Arm Embedded Toolchain for the purpose of building Rust and functional binaries.

## Building

The target can be built by enabling it for a `rustc` build.

    [build]
    target = ["aarch64-kmc-solid_asp3"]

Make sure `aarch64-kmc-elf-gcc` is included in `$PATH`. Alternatively, you can use GNU Arm Embedded Toolchain by adding the following to `bootstrap.toml`:

    [target.aarch64-kmc-solid_asp3]
    cc = "arm-none-eabi-gcc"

## Cross-compilation

This target can be cross-compiled from any hosts.

## Testing

Currently there is no support to run the rustc test suite for this target.

## Building Rust programs

Building executables is not supported yet.

If `rustc` has support for that target and the library artifacts are available, then Rust static libraries can be built for that target:

    $ rustc --target aarch64-kmc-solid_asp3 your-code.rs --crate-type staticlib
    $ ls libyour_code.a

On Rust Nightly it's possible to build without the target artifacts available:

    cargo build -Z build-std --target aarch64-kmc-solid_asp3
