4.4. System Settings (CM4)
4.4.1 USB 2.0 Hub Ports
MANTA M8P is designed with a USB 2.0 Hub, in order to save power
consumption, the USB port of CM4 is disabled by default. If you want to enable it,
you need to add the following content to the config.txt file:
dtoverlay=dwc2,dr_mode=host
4.4.2 DSI1 Display Interface
The default display interface is HDMI. The onboard DSI port of MANTA M8P uses
the DSI1 interface. You need to download the DSI1 driver and enter the following
sentence in the command line:
sudo wget https://datasheets.raspberrypi.com/cmio/dt-blob-disp1-cam1.bin -O /boot/dt-
blob.bin
After downloading this driver and restarting, the screen of DSI1 will work normally.
If you want to use the HDMI interface, you need to delete the downloaded
/boot/dt-blob.bin driver and restart, then the HDMI can output normally.
4.4.3 CSI1 Camera
The DSI1 driver downloaded in 4.4.2 DSI1 Display Interface also includes the
CSI1 driver. If you just want to install the CSI1 driver, not DSI1, please find the
driver you want to use at
https://datasheets.raspberrypi.com/licence.html and
download it in the boot folder of CM4 and rename it to dt-blob.bin , and then refer
to the settings here.
