# uf2conv

Adds a uf2 header [Microsofts HID Flashing Format (UF2)](https://github.com/microsoft/uf2/blob/86e101e3a282553756161fe12206c7a609975e70/README.md) for copying over to UF2 bootloader mass storage devices. UF2 is factory programmed extensively by [Microsoft MakeCode](https://www.microsoft.com/en-us/makecode) and [Adafruit](https://www.adafruit.com/) hardware.

## Install

`cargo install uf2conv`

## Usage

```bash

 $ uf2conv

error: The following required arguments were not provided:

    

USAGE:

    uf2conv  --base  --family  --output 

For more information try --help

```

Base usage you'll want to give the --base memory address for your chip. This is where the code starts after the bootloader. In the case of embedded rust, thats found in your memory.x where you'll find  `FLASH (rx) : ORIGIN = 0x00000000+0x4000` or `FLASH (rx) : ORIGIN = 0x00000000 + 16K` Where 16K in bytes is 16384 decimal or 0x4000 hex base.

```bash

$ uf2conv pygamer_blinky_basic.bin --base 0x4000 --output pygamer_blinky_basic.uf2

```

And you can copy that uf2 file to your embedded device's drive that appears when you enter bootloader mode.

## Rust: How to get a bin file

Use [cargo-binutils](https://github.com/rust-embedded/cargo-binutils) which replaces the `cargo build` command to find and convert elf files into binary. 

Install the dependencies

```bash

$ rustup component add llvm-tools-preview

$ cargo install uf2conv cargo-binutils

```

Then in your embedded project, say [PyGamer](https://github.com/atsamd-rs/atsamd/tree/master/boards/pygamer)

```bash

$ cargo objcopy --example blinky_basic --features unproven --release -- -O binary pygamer_blinky_basic.bin

$ uf2conv pygamer_blinky_basic.bin --base 0x4000 --output pygamer_blinky_basic.uf2

```
