La carte HiFive1 au format compatible arduino<\/figcaption><\/figure>\n\n\n\n

La carte de d\u00e9veloppement Hifive1<\/a> contient le premier microcontr\u00f4leur \u00e0 base de RISC-V<\/a> sortie en \u00absilicium\u00bb : le E310<\/a>. La Hifive1 officiellement support\u00e9e par Zephyr depuis un petit bout de temps, son utilisation devrait donc passer comme une lettre \u00e0 la poste contrairement au GD32VF103 de la Longan Nano.<\/p>\n\n\n\n

Tout d’abord initialisons un projet zephyr :<\/p>\n\n\n

$ west init ~\/zephyrhifive\n$ cd ~\/zephyrhifive\n$ west update<\/code><\/span><\/pre>\n\n\n

Attention<\/strong><\/p>\n\n\n\n
Une fois flash\u00e9, c’est une application Zephyr qui tourne sur la carte. Or zephyr part en veille s’il n’a plus rien \u00e0 faire. Ce qui est le cas ici.<\/p>\n\n\n\n
Et quand la hifive1 est en veille on ne peut plus la flasher, l’erreur du type suivant survient :<\/p>\n\n\n
<code<\/span>><\/span>Error: Timed out waiting for debug int to clear.Increase timeout with riscv set_command_timeout_sec. Error: Debug interrupt didn't clear.<\/code<\/span>><\/span><\/code><\/span>Langage du code\u00a0:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
Pour r\u00e9soudre ce probl\u00e8me on peut appuyer sur le bouton reset puis le bouton wake et enfin lancer la commande de flashage.<\/p>\n","protected":false},"excerpt":{"rendered":"
