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 arm-none-eabi-newlib - 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://developer.arm.com/open-source/gnu-toolchain/gnu-rm
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
-
Run
make deps .to patch the linker with support for the Tomu and clone the Gecko SDK locally -
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.
