Display Hit or Miss At Power On When Using External Power Supply - Raspberry Pi Forums

-

hello,

have run intermittent issue 7" rpi screen whereby unit not recognized @ startup if powered using micro-usb , both pi , screen powered on @ same moment (ie if power supply has on/off both). assume because screen may take second or power on perhaps? , in interim goes unrecognized pi?

have tried setting boot_delay of 8 seconds in config, seems have made little less often, hasn't eliminated completely.

problem goes away if power unit via gpio, setup makes less optimal due power needs.

appreciate advice. thanks.

i run pi , pi foundation screen same power source. no on off switch, plug in. no such issue here. mine 5v 10a power supply. max current rating of supply?

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention
