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

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:

cd ~/esp
git clone -b v5.1.1 --recursive https://github.com/espressif/esp-idf.git
cd ~/esp/esp-idf && git checkout e088c3766ba440e72268b458a68f27b6e7d63986 && ./install.sh --enable-gdbgui esp32 esp32s3

Set up the environmental variables:

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

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

_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.
