USB stick - system crash

Florent posted Jun 17 '19, 15:31:


My sampler box is working fine, however, I can't use a USB stick to have the samples.
When I use one, the system crash (it's trying to boot it I guess) so I can't access to the console to see what's wrong.
I used an old one (data traveler 102 8GB) and a new one (SamDisk 32GB), both formated as fat32.
I'm using a raspberry pie 2

Did anyone had the same problem in the past? Would be cool if I could avoid buying a new one!

New to me :-)
If you attach an HDMI screen and USB keyboard and then boot, you can see what's going on and login too.

Hey, thanks for the answer

When I'm doing that, it's launching the program and crash just after it, so I don't have the time to log in. I suspect that it's trying to boot the USB stick. I formatted them using different tools but still the same thing.

Little update: I got a new USB stick and same problem.
However, I noticed that the system is crashing only when both USB stick and midi keyboard are plugged. I have a arturia keystep. So power problem? I'll try to make the midi work to see.

Could be a possibility. You should use a 2mA power adapter (for Pi3 even 3mA), if you have this already then this isn't.
However what I would try too:

Startup without USB.
Stop the running background script with 'systemctl stop samplerbox'.
CD to SamplerBox dir and start manually with './' or 'python' and look for any weird messages.
You can now also test the midi/sound with the onboard saw. For the Arturia you the din interface on the PI or use a USB adapter.
Stop the script with ctrl-C.
Insert the stick (and look for..etc)
Start the script again (and look...)

It won't solve anything yet, but you get a better insight on what's happening.

Oops, ofcourse it's A, not mA...

Indeed, my power adapter is definitely not powerful enough!
I'll try to find an appropriate one
Thank you! Florent
