If you want to build device firmware, make sure you have the
[GNU ARM Embedded toolchain](https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads) installed.
You will also need Python 3.5 or later and [pipenv](https://pipenv.readthedocs.io/en/latest/install/).
* If you want to build the emulator instead of the firmware, run `export EMULATOR=1 TREZOR_TRANSPORT_V1=1`
* If you want to build with the debug link, run `export DEBUG_LINK=1`. Use this if you want to run the device tests.
* When you change these variables, use `script/setup` to clean the repository
1. To initialize the repository, run `script/setup`
2. To build the firmware or emulator, run `script/cibuild`
2. To initialize a Python environment, run `pipenv install`
3. To build the firmware or emulator, run `pipenv run script/cibuild`
If you are building device firmware, the firmware will be in `firmware/trezor.bin`.
You can launch the emulator using `firmware/trezor.elf`. To use `trezorctl` with the emulator, use
`trezorctl -t udp` (for example, `trezorctl -t udp get_features`).
If `trezorctl -t udp` appears to hang, make sure you have run `export TREZOR_TRANSPORT_V1=1`.
`trezorctl -p udp` (for example, `trezorctl -p udp get_features`).
