To build you can use the docker image (see Dockerfile) or install the esp-idf toolchain and repo following the commands in this readme.

Note the supplied docker-compose.yml assumes the Jade device is at dev/ttyUSB0.

(local)$ docker-compose up -d
(local)$ docker-compose exec dev bash
(docker)$ cp configs/sdkconfig_jade.defaults sdkconfig.defaults
(docker)$ idf.py flash

The docker-compose.yml also mounts the local git repo so that it is the origin of the repo in the docker.

Jade requires the esp-idf sdk.

More information is available in the Espressif official guide.

Get the esp-idf sdk and required tools:

cd ~/esp
git clone -b v4.2 --recursive https://github.com/espressif/esp-idf.git
cd ~/esp/esp-idf && git checkout c40f2590bf759ff60ef122afa79b4ec04e7633d2 && ./install.sh

Set up the environmental variables:

. $HOME/esp/esp-idf/export.sh

mkdir $HOME/jade
git clone --recursive https://github.com/Blockstream/Jade.git $HOME/jade
cd $HOME/jade
cp configs/sdkconfig_jade.defaults sdkconfig.defaults
idf.py flash monitor

There are various build configurations used by the CI in the configs/ directory, which may be required for specific builds eg. without BLE radio, with the screen enabled (or disabled, as with the CI tests), or for specific hardware (eg. the m5-fire).

The menuconfig tool can also be used to adjust the build settings.

idf.py menuconfig

Note: for any but the simplest CI-like build with no GUI, no camera, no user-interaction etc. it is recommended that PSRAM is available and enabled. ( Component Config -> ESP-32 specific -> Support external SPI connected RAM )

cd $HOME/jade
virtualenv -p python3 venv3
source venv3/bin/activate
pip install -r requirements.txt

python test_jade.py

deactivate
