# Test whether the environment is set up correctly.
$ python -c "import click; print('click ok')"

# Enter the core directory and install dependencies.
$ cd core

$ make vendor


# Note: if the code has not changed but you build the firmware repeatedly, it will error because the file already exists.
# A normal build will print something like: cp build/firmware/firmware.bin build/firmware/firmware-T3T1-2.11.2-6daa3bd.bin (trezor-firmware)
$ make build_firmware 
# For example, if the device model is T3B1, specify the environment variable.
$ TREZOR_MODEL=T3B1 make build_firmware

# TREZOR_MODEL=T3B1 make upload

# Device list, used to confirm the device is connected and recognized correctly.

# At this point, trezorctl commands should work. For example, trezorctl list can show the device list.

# This will trigger firmware flashing on the physical device. You can also use Trezor Suite to flash firmware.
