Projet de Streamer à base de Raspberry

[0000]

J'ai retrouvé un lien parlant de l'ancienne RPi (celle ayant deux ports usb et 256mo Ram) dont l'usb ne peut pas fournir plus que 140mA. C'est peut-être la cause de mon problème. http://elinux.org/RPi_Hardware

Citation :Each of the two USB ports on the Pi has a polyfuse rated at 140 mA, so any connected USB devices should draw less than this amount of current. In addition the polyfuse will cause a significant voltage drop, so that USB devices get less voltage than is available on the RPI itself, sometimes up to half a volt less (maybe more if the fuse has recently been hot). For regular "low power" USB devices this doesn't cause a problem as they are designed to work with voltages as low as 4.4 Volt. This isn't the case however with some USB devices such as WiFi dongles which may need 4.75 Volt, and are also known to draw more than 150 mA when configured and active. Because of the problems these polyfuses caused Raspberry PI's produced after August 25, 2012 have the USB polyfuses F1 & F2 removed (replaced with shorts).

Je teste actuellement RPi + piCore + batterie. Cela me semble une excellente combinaison. Avec piCore, on peut débrancher RPi sans crainte de corruption du système. Ma batterie de 16 000 mAh peut tenir plusieurs jours d'écoute.
