Hi all, A cross post from https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=247325&p=1510382#p1510382 as I'm not sure which area is best to post on. Essentially: Please forgive me if I've missed another forum post that already includes this information but I've struggled to find anything defin...

I've realised I've made a rookie error that I was missing the -a argument on so I wasn't receiving the full output however my device is still not working but its fine on the USB one.

Is there anything I could be missing that's interfering with ttyAMA0 or ttyS0?

Hi all, Please forgive me if I've missed another forum post that already includes this information but I've struggled to find anything definitive. I have a device that requires us to use a 3.3 TTL interface to it. It states in it's documentation: Baud rate – 9600 Data bytes – 8 Parity – None Stop bi...

Brilliant, thanks for confirming this

Hi all, A while ago I started using the CM3 and used https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-display.md to build a custom dt-blob.bin to enable the display. I'm not revisiting this as I want to use Noobs with the device and found I could only get the display to work wit...

OK so I've reproduced this in house. dmesg shows: mmc0: card never left busy state mmc0: error -110 whilst initialising SD Card EXT4-fs error (device mmcblk0p2): previous I/O error to duperblock detected We are using Kingston Industrial SD Cards so I know the SD Cards are up to the task. Also, simpl...

it appears to happen after the devices have been running for 10 days.
Again it doesn't happen to all the devices just a number of them our in the field

the keepalive is more of a "im alive" it doesn't actually take any hardware actions like rebooting or anything.

Memory definitely isn't the issue as our keepalive checks this and simply overwrites the file. I did note that my last syslog message was missing additional log items that were in the roll over file.

Alas we don't it appears to happen on our remote devices. After we get the devices manually rebooted syslog has only shown periodic jobs running every minute and then the reboot and it starting back up. We are working on trying to recreate the issue locally with a terminal open with keyboard and mou...

I forgot to add, it sounds very similar to viewtopic.php?t=156287 but we don't use a camera nor have the library mentioned at the end of the post installed

Hi all, We are running raspbian stretch and have our mono based application running fine however we've found that after several days (this can be 2 days it could be 7) that our PI's just hang.

Hi all, I'm using the Compute Module 3 with eMMC Flash and the IO Board v3. I'm trying to configure it in a way where it boots from eMMC by default but if a push switch is held during boot it will boot from a USB stick. Essentially providing a way to "factory" reset the software, ie boot a tiny kern...
