# Build instructions for Embedded (ARM port)
|
||
|
|
|
||
|
|
First clone, initialize submodules and install Pipenv as defined [here](index.md).
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
You will need the GCC ARM toolchain for building and OpenOCD for flashing to a device.
|
||
|
|
You will also need Python dependencies for signing.
|
||
|
|
|
||
|
|
### Debian/Ubuntu
|
||
|
|
|
||
|
|
```sh
|
||
|
|
sudo apt-get install scons gcc-arm-none-eabi libnewlib-arm-none-eabi
|
||
|
|
```
|
||
|
|
|
||
|
|
### OS X
|
||
|
|
|
||
|
|
1. Download [gcc-arm-none-eabi](https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads)
|
||
|
|
2. Follow the [install instructions](https://launchpadlibrarian.net/287100883/readme.txt)
|
||
|
|
3. To install OpenOCD, run `brew install open-ocd`
|
||
|
|
4. Run `pipenv run make vendor build_boardloader build_bootloader build_firmware`
|
||
|
|
|
||
|
|
## Building
|
||
|
|
|
||
|
|
```sh
|
||
|
|
pipenv run make vendor build_boardloader build_bootloader build_firmware
|
||
|
|
```
|
||
|
|
|
||
|
|
## Uploading
|
||
|
|
|
||
|
|
Use `make upload` to upload the firmware to a production device. Do not forget to [enter bootloader](https://wiki.trezor.io/User_manual-Updating_the_Trezor_device_firmware__TT) on the device beforehand.
|
||
|
|
|
||
|
|
## Flashing
|
||
|
|
|
||
|
|
For flashing firmware to blank device (without bootloader) use `make flash`,
|
||
|
|
or `make flash STLINK_VER=v2-1` if using a ST-LINK/V2.1 interface.
|
||
|
|
You need to have OpenOCD installed.
|
||
|
|
|
||
|
|
## Building in debug mode
|
||
|
|
|
||
|
|
You can also build firmware in debug mode to see log output or run tests. To avoid building firmware in debug mode accidentally, we do not provide a _make_ target. You need to rewrite `PYOPT` variable to `0` in `SConscript.firmware` file and then build the same way. The change is intentionally not _gitignored_.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
sed -i "s/^PYOPT = '1'$/PYOPT = '0'/" SConscript.firmware
|
||
|
|
pipenv run make build_firmware
|
||
|
|
```
|
||
|
|
|
||
|
|
You can then use `screen` to enter the device's console. Do not forget to add your user to the `dialout` group or use `sudo`. Note that both the group and the tty name can differ, use `ls -l` to find out proper names on your machine.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
screen /dev/ttyACM0
|
||
|
|
```
