Emulator

1. build the emulator
2. run emu.sh
3. to use bridge with the emulator support, start it with trezord -e 21324

Profiles

To run emulator with different flash and sdcard files set the environment variable TREZOR_PROFILE like so:

TREZOR_PROFILE=foobar ./emu.sh

This will create a profile directory in your home ~/.trezoremu/foobar containing emulator run files.

Alternatively you can set a full path like so:

TREZOR_PROFILE=/var/tmp/foobar ./emu.sh

When the TREZOR_PROFILE is not set the default is /var/tmp .
