Project progress
The final prototypes are currently being manufactured over at JLCPCB. Meanwhile we are working on the launcher firmware which will allow users to install and run firmware binaries like apps. The launcher menu shows a list of installed apps (firmwares). When an app is selected the ESP32-P4 will reboot into the selected app.
AppFS is a combination of a firmware “filesystem” and an addition to the bootloader which allows installing and starting multiple firmwares dynamically. It was created originally as a way to install multiple applications on the PocketSprite keychain gameconsole. In 2022 we used the AppFS component as the core of the MCH2022 event badge launcher firmware.
Since then we have in collaboration with the awesome people from Badge.Team updated the AppFS code to make it work with the latest ESP-IDF revision and we have added support for the ESP32-C6 and ESP32-P4. We have published the updated and improved AppFS component which forms the basis of the Tanmatsu™ launcher firmware on GitHub and the ESP component registry.

While waiting on the ESP32-P4 to become available in larger quantities, we will be working on finishing a fully featured launcher firmware for the Tanmatsu™ with OTA firmware updating support.
