CM4 2gb lite version, raspios, and usb ports

[jaymcd]

I have the PAD 5 - I finally managed to get a CM4 ( 2GB lite version) I managed to get RaspiOS ( Raspian) installed. Even after following the instructions in the manual - including the overlay stuff I cannot for the life of me get the USB ports to be usable. Wondering what I am missing

Hi @jaymcd I had the exact same problem. What fixed it for me was setting the BOOT and USBOTG switches to their off position. Had them on because I previously used a CM4 with eMMC.

installng Fluiddpi 1.19 using LITE Version(Micro SD card) ssh already in image add wpa credencials in fluiddpi-wpa-supplicant.txt configure USB 2.0 Hub in config.txt file verification of microswith (all off) result: Red light and Blue but no Green :(

Did I miss something ?

As described in the data sheet of the CM4 from Pi-Foundation and in the manual from BigTreeTech:

"With the Raspberry Pi OS the following has do be done to activate the USB-Ports for the CM4: To enable the USB 2.0 ports on the Compute Module 4, you need to edit the boot config file (/boot/config.txt) and add with the last row:

dtoverlay=dwc2,dr_mode=host

It is deactivated by default in the OS of RaspiOS to save energy.

Hi,

As I said in the last mail. I did the configuration as explained in the BigTreeTech Manual. (https://github.com/bigtreetech/Raspberry-Pad/blob/master/Pad5/BIGTREETECH%20Raspberry%20pad%205%20V1.0%20%20Manual.pdf) Please see the attachments and video.

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

overscan_left=16

overscan_right=16

overscan_top=16

overscan_bottom=16

uncomment to force a console size. By default it will be display's size minus

overscan.

uncomment if hdmi display is not detected and composite is being output

hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

hdmi_group=1

hdmi_mode=1

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

This line should be removed if the legacy DWC2 controller is required

(e.g. for USB device mode) or if USB support is not required.

still cannot get by usb ports to work. I even sent my cm4 back and they sent a new one... ??? pios installed screen working but getting usb to work - not so much. I am usb the USB-C for power does that matter ? It is plugged into a powered USB. I also get a brcm pci link is down message along with a bunch of usb errors on boot. One of whic is hub 2.0 failed - doesn't have any ports . when it boots ????

Just noticed this section in you config:

[cm4]
# Enable host mode on the 2711 built-in XHCI USB controller.
# This line should be removed if the legacy DWC2 controller is required
# (e.g. for USB device mode) or if USB support is not required.
otg_mode=1

I'll have to check on my setup tomorrow, but I don't remember a cm4 section in mine. Maybe removing the org_mode=1 could help.

In the past I had a problem when adding any commands below a section (e.g. [cm] or [all]) and had to add it above any of those (but this might be a non issue and it used to be a different problem back then 😄)

No USB or Wifi. Moved my CM4 over to a CMIO module board - USB works fine but not WIFI ( obviosuly a broadcom driver issue). There is either something wrong with my PAD 5 or the instructins are incorrect. I have tried everything suggested to no avail. Anyone havea working image? Still no reply...
