Board support crate targeted for [Tim's Open Micro USB](http://tomu.im/)

Includes support for tomu-bootloader config (toboot v2).

work in progress

- [X] toboot config

- [ ] timers

- [X] GPIO (most of the functionality is implemented)

- [ ] USB

- [ ] AES

dependencies

---

To build embedded programs using this template you'll need:

- Rust stable, ie 1.31 or a newer toolchain.

- `rust-std` components (pre-compiled `core` crate) for the ARM Cortex-M

  targets. Run:

``` console

$ rustup target add thumbv6m-none-eabi

```

- llvm-tools-preview for `llvm-objcopy` to turn the elf into a binary for uploading. Run:

``` console

$ rustup component add llvm-tools-preview

```

- The [dfu-util](https://tomu.im/update#installing-dfu-util)

usage

---

```

cargo run --example blink --release

```

toboot config

---

Application can interact with tomu bootloader by using `toboot_config` macro.

It's fully typesafe so there's no need to worry you're putting wrong config. It will even warns you if you're trying to lock bootloader entry like this:

```rust

toboot_config! {

    lock_entry: true,

}

```

![warns](https://f4.fudan.ch/shx/putty_(3)_2019-01-28_13-43-45.png)

Full config as the following:

```rust

toboot_config! {

    config: [autorun_enable, irq_enable],

    lock_entry: false,

    // efm32hg309f64 has 64KiB flash memory,

    // each bit below represent 1 sector (1KiB)

    // which will be erased when tomu load its bootloader

    erase_mask_lo: 0, // 32bit uint

    erase_mask_hi: 0, // 32bit uint

}

```
