Octoprint Pi 4 USB web cam and Fixing wifi loss

marcus · January 2, 2022, 4:44am

I've noticed to get a USB webcam working on a Pi I need to have the 3D printer turned on with a valid connection to the Pi, in order to actually view the stream. Is this by design ? As the Pi is connected to the camera via USB, and shouldn't need a connection to the printer at all.

Anyway I hit another problem with installation, as my Pi 4 running Octoprint Pi 4 was losing comms to my PC, and hence the web portal.

If you find that you lose comms to your Raspberry Pi 4 while running Octoprint, connect via head mode (ie with HDMI, keyboard, mouse etc). Then check the messages in the linux log

sudo dmesg | grep brcmf

If you see any errors with -110, then the wifi firmware has crashed

ieee80211 phy0: brcmf_run_escan: error (-110)
ieee80211 phy0: brcmf_cfg80211_scan: scan error (-110)

This seems to be a problem with the latest Octoprint Pi image

OctoPrint Version 1.7.2
OctoPi version 0.18.0

You can repair it by downloading and copying the latest wifi firmware into the following folder

cd /lib/firmware/brcm

Backup original firmware first

sudo cp brcmfmac43455-sdio.bin brcmfmac43455-sdio.bin.orig

Then download the fixed one from here (or find a legitimate source)

New Wifi FW

And copy the downloaded firmware into the lib folder

sudo cp ~/Downloads/ brcmfmac43455-sdio.bin /lib/firmware/brcm/.

Then

sudo reboot

You can find the full problem and solution on this thread

RPi4: WiFi client crashes often (brcmf_fw_crashed: Firmware has halted or crashed)

Wifi Issue

**Describe the bug** WiFi client stops working and does not recover (Cypress fi…rmware crashes). This happens to my RPi4 almost every day and I must reboot to recover it. After reboot, it always works but will fail again sometime later that day (duration seems random). Raspbian is up to date with all upgrades as of 9/11/2020. **To reproduce** Use WiFi client mode on RPi4. **Expected behaviour** WiFi keeps working reliably. **Actual behaviour** WiFi client stops functioning entirely. **System** * Which model of Raspberry Pi? e.g. Pi3B+, PiZeroW Raspberry Pi 4 (4GB) * Which OS and version (`cat /etc/rpi-issue`)? Raspbian GNU/Linux 10 * Which firmware version (`vcgencmd version`)?
