Re: Help: Three identical Pis. One SD card. Only one Pi boot

It's a long story as to why we don't update more frequently so I'll spare that explanation here. You're right though, I checked and we didn't have any problems with the first batch of our kits, this started happening with a re-order of a couple hundred units. The failure rate is low (under 3%) so sp...

Re: Help: Three identical Pis. One SD card. Only one Pi boot

Sorry if this wasn't clear in the original post - this is a kit with a pre-flashed SD card. Changing anything on the card is not an option at this point. I was just trying to reverse-engineer to figure out what happened and it appears that overclocking was the problem. The crash happens during boot,...

Re: Help: Three identical Pis. One SD card. Only one Pi boot

Circling back to answer my own question...looks like the problem was caused by overclocking. I forgot to mention in the original post that our SD card comes overclocked to Turbo. If I reset overclocking to "none" on a card using the working Pi, then the other two Pis boot fine. If I set those back t...

Help: Three identical Pis. One SD card. Only one Pi boots.

I work for a small nonprofit that developed a Raspberry Pi kit and curriculum based on the Model B+. Our kit includes an SD card with slightly customized version of Raspbian from 2014 (we don't have the manpower to keep up with hardware/software updates as fast as they come out, so this is what I've...

Re: MIDI Instruments?

I did notice that over 3.5mm, each sound has a pretty long fade-out that seems to last a second or two - much longer than half a beat or whatever I had set in the block. So, maybe you can't actually hear that over HDMI (it's quieter than the initial noise), but technically it's still playing, causin...

Re: MIDI Instruments?

Aaaand I started going through this line by line as you suggested but didn't get far.

Code: Select all

sudo apt-get -y install timidity timidity-daemon
ran fine and no problems with immediate reboot.

Code: Select all

sudo apt-get fluid-soundfont-gm fluid-soundfont-gs
Gives the error "E: invalid operation fluid-soundfont-gm"

Haven't had a chance to try any of your step-by-step directions yet, but small update...I actually have a black screen with a single blinking cursor all the way in the upper left corner! That seems better than a totally blank screen. At least it has a pulse.

Re: MIDI Instruments?

If it's worth anything - I rolled back to the September release of Jessie and tried again, and the installation worked without causing a crash. The instruments still don't work in Scratch, but I assume that's to be expected since support wasn't added until the November release. This is all on a Pi 2...

A cheap one might provide 5v at 150mA but when its supplying 1000mA the voltage has tailed off to 2v (or often worse).
