Re: Newly purchased RPI 3B+ wont boot from older image

oh boy, that is a lotta messing.... cant believe the peeps at RPI would make it so difficult to upgrade... I don't think for a moment that they made it difficult. More likely their brief was to produce a utility that made it simple to perform an initial install of Raspbian. (And there are those who...

Re: Backup Tool?

For 'backups' - not images - there is the SD Card Copier utility in the Raspbian Desktop drop down menu system.

Re: No response from gpio ports

Thank you. The tests fail miresably. So, because linux works well, can the board be used for, let's say, as a wifi access point? I'd immagine so.

Re: Problem with boot from USB on raspberry pi 3 b+

Likely the best solution will be to use a powered USB hub.

Is it still necessarry to use a powered USB hub even in this case? Even the logic circuits in t...
