Des passionn\u00e9s ont r\u00e9ussi \u00e0 charger un environnement bas\u00e9 sur le noyau Linux 5.0 sur la carte ESP32 avec un processeur dual-core Tensilica Xtensa (carte esp32 devkit v1, sans MMU complet), dot\u00e9 de 2 Mo de Flash et 8 Mo de m\u00e9moire PSRAM, connect\u00e9 via une interface SPI. Une image de firmware Linux pour l'ESP32 a \u00e9t\u00e9 pr\u00e9par\u00e9e pour le chargement. Le chargement prend environ 6 minutes. <\/p>\n

Le firmware a \u00e9t\u00e9 form\u00e9 \u00e0 partir de l'image de la machine virtuelle JuiceVm et du port du noyau Linux 5.0. JuiceVm fournit un cadre minimal pour les syst\u00e8mes RISC-V, capable de se charger sur des puces avec quelques centaines de kilo-octets de m\u00e9moire vive. JuiceVm permet le d\u00e9marrage d'OpenSBI (RISC-V Supervisor Binary Interface), une interface de liaison pour le chargement du noyau Linux et un environnement syst\u00e8me minimal \u00e0 partir d'un firmware sp\u00e9cifique \u00e0 la plateforme ESP32. En plus de Linux, JuiceVm supporte \u00e9galement le chargement de FreeRTOS et RT-Thread.
