Thank you. A couple of questions. Well, three, actually. 1. Where do I go to learn more about this "journaling" of which you speak? I'd like to learn how this can help protect my little Pi project from an abrupt loss of power. 2. Right, USB "thumb drives" are flash, like SD cards. But people routine...
Leaving aside the stir of excitement caused by that troll, I wanted to get back to the issue of powering off a Pi without allowing the the SD card to perform its maintenance procedures, which risks corrupting the card. Is this a problem with a Pi that has been set to boot and operate from flash memo...
I personally don't see what the big deal with sd card failures? The simple solution would be to make a clone of the sd card to have a backup just-in-case of a sd failure. Just my .05 cents (would be .02 cents, but because of inflation). :D :D :D Respect. But in this case the device is supposed to r...
All good advice, but the temp sensor on my Pi 3's shows typical temp around 40 degrees C. That's not anywhere near dangerous for chip. Still and all, heat is the enemy of electronics.
Often people turn off the power immediately after linux has shut down, but they forget that the SD-card doesn't know about imminent shutdowns, and can start a wear levelling process just at the worst time, after a final last batch of writes, when Linux does a cache flush for a shutdown. If you turn...
It's not experimental. It's documented at: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md It went mainstream with the 4.4.50 kernel and is included in the 4.9.?? kernels. Thanks, DougieLawson and W.H. Heydt. I saw that page before I posted. The second sentence reads...
That is no longer true. Since early April this year the Raspbian downloads have included the boot-from-USB code. You still have to set the OTP bit so that a BCM2837 *will* boot over USB given the opportunity, but that process is well documented. And--FYI--it would work on a Pi2B2 and I've done it o...
Please, kind people, don't let this thread get all kind of flamey! I'm hoping for engineering advice so I can build up a dependable little solution. Here's my thinking so far: All hardware can (and, eventually will) fail. Electrolytic capacitors have limited lifespan. So keep a spare (or two) of the...
I'd like to set up a Raspberry Pi at our community radio station to be used to livestream the station's music and shows. We're presently using a funky old donated laptop running Linux, but who knows how long that thing will keep running? The same software that does our streaming from the laptop, but...
