Troubleshooting information for Raspberry Pi 400
Terminal Closes On Update
When you push updates, the terminal session is automatically closed. To restart the terminal session, simply close the terminal session and restart it once the update is complete.
Can't Login to the Dashboard
In some cases social logins can be disrupted or completely borked by Adblocker or browser extensions such as BrowserShark. Make sure to disable these extensions or whitelist the
$'\r': command not found when my device tries to run scripts
Line endings differ between Windows and the Unix-y world (they used to be different again for Mac but not for many years), which can result in issues. E.g. a user seeing something like: /usr/src/app/run.sh: line 2: $'\r': command not found
To resolve this, you will need to configure git to automatically convert line endings. In order to configure this for Windows have a look here: https://help.github.com/articles/dealing-with-line-endings/#platform-windows.
Device keeps dropping off wifi
If your device keeps dropping offline, it may be worth switching to a 5GHz band wifi dongle, as we have seen cases where 2.4GHz gets badly affected by surrounding noise.
Unsupported Syscall: 384 from qemu on builder
The qemu: Unsupported syscall: 384 is a warning that the getrandom(2) system call is not implemented by our emulation layer, qemu. It can be safely ignored. Since it's a fairly new system call (introduced in kernel 3.17),
apt and almost all programs automatically fall back to reading from
/dev/urandom when this syscall fails.
Help! My device won't show up.
If your device still hasn't shown up on your dashboard after 10 minutes, something is definitely wrong. First check that you entered the WiFi credentials correctly (if you need help fixing your credentials, see WiFi Help) and ensure that your network meets these basic requirements. It may also be worth checking the LED error notifications.
If you have an HDMI screen attached, you should see balena logo on the screen when the device boots. If instead you see rainbow colors or a blank screen, it could mean that the SD card was not burned correctly or is corrupted.
If you still can't get your device online, come on over and talk to us on our support channel.
