Vorago VA416xx Rust Support
|
|
=========
|
|
|
|
This crate collection provided support to write Rust applications for the VA416XX family
|
|
of devices.
|
|
|
|
## List of crates
|
|
|
|
This workspace contains the following crates:
|
|
|
|
- The `va416xx` PAC crate containing basic low-level register definition
|
|
- The `va416xx-hal` HAL crate containing higher-level abstractions on top of
|
|
the PAC register crate.
|
|
- The `vorago-peb1` BSP crate containing support for the PEB1 development
|
|
board.
|
|
|
|
## Using the `.cargo/config.toml` file
|
|
|
|
Use the following command to have a starting `config.toml` file
|
|
|
|
```sh
|
|
cp .cargo/def-config.toml .cargo/config.toml
|
|
```
|
|
|
|
You then can adapt the `config.toml` to your needs. For example, you can configure runners
|
|
to conveniently flash with `cargo run`.
|
|
|
|
## Using the sample VS Code files
|
|
|
|
Use the following command to have a starting configuration for VS Code:
|
|
|
|
```sh
|
|
cp vscode .vscode -r
|
|
```
|
|
|
|
You can then adapt the files in `.vscode` to your needs.
|
|
|
|
## Flashing, running and debugging with the command line
|
|
|
|
### Prerequisites
|
|
|
|
1. [SEGGER J-Link tools](https://www.segger.com/downloads/jlink/) installed
|
|
2. [gdb-multiarch](https://packages.debian.org/sid/gdb-multiarch) or similar
|
|
cross-architecture debugger installed. All commands here assume `gdb-multiarch`.
|
|
|
|
### Flashing and debugging the blinky application
|
|
|
|
You can build the blinky example application with the following command
|
|
|
|
```sh
|
|
cargo build -p va416xx-hal --example blinky
|
|
```
|
|
|
|
Start the GDB server first. The server needs to be started with a certain configuration and with
|
|
a JLink script to disable ROM protection.
|
|
For example, on Debian based system the following command can be used to do this (this command
|
|
is also run when running the `jlink-gdb.sh` script)
|
|
|
|
```sh
|
|
JLinkGDBServer -select USB -device Cortex-M4 -endian little -if SWD -speed 2000 \
|
|
-LocalhostOnly -vd -jlinkscriptfile ./jlink/JLinkSettings.JLinkScript
|
|
```
|
|
|
|
After this, you can flash and debug the application with the following command
|
|
|
|
```sh
|
|
gdb-mutliarch -q -x jlink/jlink.gdb target/thumbv7em-none-eabihf/debug/examples/blinky
|
|
```
|
|
|
|
Please note that you can automate all steps except starting the GDB server by using a cargo
|
|
runner configuration, for example with the following lines in your `.cargo/config.toml` file:
|
|
|
|
```toml
|
|
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
|
|
runner = "gdb-multiarch -q -x jlink/jlink.gdb"
|
|
```
|
|
|
|
After that, you can simply use `cargo run -p va416xx-hal --example blinky` to flash the blinky
|
|
example.
