Jade Firmware

NOTE: the below instructions are for Jade developers with access to Jade development boards or for those wanting to build and flash their own esp32 consumer devices - eg. M5Stack or TTGO T-Display boards. They are not for updating the firmware of an official Blockstream Jade hw unit - these can only be updated in-app, or using the 'update_jade_fw.py' script - see FWUPDATE.md

• DO NOT ATTEMPT THE BELOW WITH BLOCKSTREAM OFFICIAL BLOCKSTREAM JADE HW UNITS

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

DIY Hardware & Programming Notes

For information about suitable DIY hardware, as well as suggested configuration profiles and notes on secure boot. DIY Guide

Use docker

If you are on MacOS, you are better off setting up the environment locally (see next step) than trying to get access to your device from the docker container. For more, see this article.

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

Note the below instructions assume an original Jade v1.0 hardware with a true wheel. When using the later Jade v1.1 hw revision with a rocker/jog-wheel, use 'configs/sdkconfig_jade_v1_1.defaults' in place of 'configs/sdkconfig_jade.defaults'.

(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.

Set up the environment

Jade requires the esp-idf sdk.

More information is available in the Espressif official guide.

Get the esp-idf sdk and required tools:

mkdir ~/esp
cd ~/esp
git clone -b v5.1.3 --recursive https://github.com/espressif/esp-idf.git
cd ~/esp/esp-idf && git checkout e7771c75bd1dbbfb7b3c5381be7e063b197c9734 && ./install.sh --enable-gdbgui esp32 esp32s3

Set up the environmental variables:

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

On MacOS: You will need cmake on your system for this step (brew install cmake).

If you encounter Python dependencies issue, make sure to use a recent Python version (e.g. Python 3.11) as the current system version which is used by the install script.

Build the firmware

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

Use a config file from the configs folder that is specific to your hardware (if available).

For example for the TTGO T-Display:

cp configs/sdkconfig_display_ttgo_tdisplay.defaults sdkconfig.defaults

If you flash multiple devices or make changes to the original config file that you used, make sure to delete the sdkconfig file that gets created from sdkconfig.defaults. Otherwise, your changes will not get picked up when building and re-flashing the firmware.

Some hardware configurations (eg: M5StickC-Plus) may not support the default baud rate and won't be detected, so you can force a specific baud rate for flash/monitor by using the -b argument.

For example, the last line of the above code block would change be:

idf.py -b 115200 flash monitor

Build configurations

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 )

Run the tests

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

python test_jade.py

deactivate

Emulator/Virtualizer (qemu in Docker)

Run these commands inside the jade source repo root directory, it will enter a docker container

DOCKER_BUILDKIT=1 docker build . -t testjadeqemu
docker run -v ${PWD}:/jade -p 30121:30121 -it testjadeqemu bash

Note: You can skip the build step if you want by fetching the prebuilt image and running with

docker pull blockstream/verde
docker run -v ${PWD}:/jade -p 30121:30121 -it blockstream/verde bash

Now inside the container

. /root/esp/esp-idf/export.sh
cd /jade
rm -fr sdkconfig
cp configs/sdkconfig_qemu.defaults sdkconfig.defaults
idf.py all
apt-get update -qq && apt-get install virtualenv -yqq
virtualenv -p python3 ./venv3
source ./venv3/bin/activate
pip install -r requirements.txt
./tools/fwprep.py build/jade.bin build
./main/qemu/make-flash-img.sh

# To run the CI tests
./main/qemu/qemu_ci_flash.sh

# To reboot the qemu instance
./main/qemu/qemu_reboot.sh

# To reboot the qemu instance and attach gdb to the Jade fw
./main/qemu/qemu_gdb.sh

At this point the Jade fw running in the qemu emulator should be available on 'tcp:localhost:30121' from inside and outside the docker container.
