Les chercheurs de Berkley qui ont fond\u00e9 le set d’instruction (ISA) Risc-V <\/a>(prononcez Risque failleve) ont \u00e9galement mont\u00e9 une soci\u00e9t\u00e9 nomm\u00e9e SiFive<\/a>.<\/p>\n

Cette soci\u00e9t\u00e9 con\u00e7oit des c\u0153urs de processeurs nomm\u00e9s Freedom Everywhere et propose \u00e0 ses clients de l’inclure dans des ASIC personnalis\u00e9. Les processeurs cr\u00e9\u00e9s restent \u00e9videmment open-source, et l’int\u00e9gralit\u00e9 du code (Chisel) est disponible sur le site de SiFive.<\/p>\n

Pour promouvoir leur processeur, SiFive a fabriqu\u00e9 un microcontr\u00f4leur 32bits nomm\u00e9 Freedom E310. SiFive a \u00e9galement r\u00e9alis\u00e9 une carte \u00abcompatible arduino\u00bb qu’il est possible de commander en crowdsourcing <\/a> pour prendre en main ce processeur.<\/p>\n

C’est ce que nous allons tester ici. Le kit est livr\u00e9 \u00absec\u00bb, pour l’alimenter il faut donc soit trouver un c\u00e2ble d’alimentation, soit d\u00e9cider de l’alimenter via l’USB comme expliqu\u00e9 dans le manuel de d\u00e9marrage<\/a>.<\/p>\n

Kit HiFive1 (compatible arduino)<\/figcaption><\/figure>\n

Le plus gros composant que l’on voit sur la carte est le convertisseur USB-S\u00e9rie et non le microcontr\u00f4leur. Le microcontr\u00f4leur se trouve \u00e0 droite avec le \u00absymbole superman\u00bb.<\/p>\n

La mise en route du kit est relativement simple dans la mesure ou tout est d\u00e9crit dans le document \u00abgetting started\u00bb.<\/p>\n
\u00c9videmment, le c\u0153ur du proc est libre, du coup la cha\u00eene de compilation l’est aussi pardi. Il suffit de la t\u00e9l\u00e9charger sur sa machine :<\/p>\n
$ git clone --recursive https:\/\/github.com\/sifive\/freedom-e-sdk.git\n<\/pre>\n
Puis<\/p>\n
cd freedom-e-sdk\nmake tools\n<\/pre>\n
Et attendre que \u00e7a compile en prenant son caf\u00e9.<\/p>\n
Dans mon cas (Debian jessie) il fallait \u00e9galement installer les packets suivant pour que \u00e7a compile:<\/p>\n
sudo apt-get install libmpc-dev\n<\/pre>\n
Un fois install\u00e9, on peut compiler la d\u00e9mo de gpio comme \u00e7a:<\/p>\n

\u00c7a n’est pas pour rien que le kit ressemble \u00e0 s’y m\u00e9prendre \u00e0 un arduino : il est possible d’utiliser l’ide d’arduino pour se connecter \u00e0 la carte.<\/p>\n
L’ide arduino se trouvant dans ma debian est trop vieux pour pouvoir ajouter la toolchaine\u00a0 sifive. J’ai donc du t\u00e9l\u00e9charger la 1.8 puis l’installer. Heureusement \u00e7a n’est pas tr\u00e8s compliqu\u00e9 :<\/p>\n
$ tar -Jxvf arduino-1.8.5-linux64.tar.xz\n$ cd arduino-1.8.5\/\n$ .\/install.sh \n$ .\/arduino\n<\/pre>\n
Une fois lanc\u00e9, il faut ajouter la configuration du package sifive en allant dans les pr\u00e9f\u00e9rences pour ajouter l’url suivante :<\/p>\n
http:\/\/static.dev.sifive.com\/bsp\/arduino\/package_sifive_index.json\n<\/pre>\n
Puis installer la plate-forme \u00absifive\u00bb via le board manager. Il faut \u00e9galement s\u00e9lectionner \u00abSiFive open ocd\u00bb comme programmeur.<\/p>\n
