Arriv\u00e9e dans un \u00e9norme carton, la carte \u00e9lectronique se trouve dans le tout petit \u00abtube\u00bb blanc.<\/figcaption><\/figure>\n\n\n\n

Je viens donc de recevoir ma carte petite abeille (littlebee) munie d’un FPGA du chinois GOWIN<\/a>. <\/p>\n\n\n\n

La carte \u00abLittleBee\u00bb munie d’un FPGA de chez Gowin<\/figcaption><\/figure>\n\n\n\n

La carte produite et vendue par la soci\u00e9t\u00e9 allemande Trenz Electronic<\/a> permet de se faire la main avec le composant pour moins de 40\u20ac (un peu plus avec les frais de ports UPS …).<\/p>\n\n\n\n

Branchement <\/strong><\/p>\n\n\n\n

Au branchement \u00e0 la sortie du carton les huit leds rouge s’allument ainsi qu’une led verte que je suppose de \u00abpower\u00bb.<\/p>\n\n\n\n

Les messages noyau nous donnent deux ports s\u00e9ries ttyUSBx :<\/p>\n\n\n\n

$ dmesg

Si on se connecte au port s\u00e9rie ttyUSB1<\/strong> on obtient un affichage de la r\u00e9solution du probl\u00e8me des philosophes<\/a>. <\/p>\n\n\n\n

Philosopher 0 [P: 3] THINKING [ 750 ms ]
Philosopher 1 [P: 2] HOLDING ONE FORK

Philosopher 4 [C:-1] HOLDING ONE FORK get back,

Il est probable que nous ayons ici un RISC-V dans le tiroir.<\/a> <\/p>\n\n\n\n

La connexion d’un terminal sur le port ttyUSB0 ne donne rien par contre.<\/p>\n\n\n\n

IDE<\/strong><\/p>\n\n\n\n

Voila pour le d\u00e9ballage, maintenant il va falloir installer les outils pour faire clignoter ces leds !<\/p>\n\n\n\n
