These projects are simple programs for the Tomu. They do various things, and are intended to offer code examples and simple testing to ease your introduction to the Tomu platform.
- To compile these, you'll need a cross-compiling toolchain to arm-none-eabi.
- Debian/Ubuntu/... :
sudo apt-get install gcc-arm-none-eabi - Fedora :
sudo yum install arm-none-eabi-gcc-cs - Arch :
sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib - Other Linux : check your package manager, or
- Anything else (Windows, OSX, Linux) : https://launchpad.net/gcc-arm-embedded/+download
If the cross compiling toolchain is in your PATH then the Makefile will
auto-detect it; else (or to override it) specify it using the environment
variable "CROSS_COMPILE".
There might be additional dependencies, depending on which specific project
you're using, and the instructions for compilation are included in each
project's README.md
2. Run make deps . to patch the linker with support for the Tomu and clone the Gecko SDK locally
3. Now you can build the examples
Once you've compiled the code, you can flash the Tomu using minicom on linux
and OSX, or some other serial I/O utility on Windows. To do that, set it up with
115200 8n1, then use i to show the bootloader version.
To upload the binary, press u, wait till the bootloader replies with Ready,
then press ^A-S, choose XMODEM, choose the .bin file produced by the
compilation, and wait until it's uploaded.
Once that's done, press b to boot into the firmware. The bootloader will hang
for 5-7 seconds, then the Tomu will boot.
