Hello mohabsi ,
I have found that commenting out

# For OAK-CM4 to show uSD card
#dtoverlay=sdhost,poll_once=off

Inside /boot/config.txt will fix this issue and you will be able to see WiFi interfaces. I am not sure what will be consequences (CM4 won't be able to use SD card? not sure), but I have yet to debug it.
Thanks, Erik

      It worked! Thanks much. I can live with this as a temporary fix.

        Hi, erik

        I just received an OAK-D CM4 and have successfully connected via Ethernet, and it looks like #dtoverlay=sdhost,poll_once=off is already commented out in /boot/config.txt but I'm still getting "No wireless interface found" via sudo raspi-config.

        Do you have any other suggestions to try?

        Thanks

            Hi kohani ,
            Does the RPi CM4 have the WiFi module on it? I think the wireless module is marked with blue arrow, while eMMC is marked with red one.

                Thank you for your response erik, no it does not seem like it. Please see attached photo. I also noticed a heat sync for the PI on some of your store photos. Is that something that was supposed to be shipped with the product or just shown as an option?

                Lastly, in trying to connect the board to RobotHub I noticed it was shipped with a 32-bit os which produces ! Unsupported architecture armv7l ! error. Is the board supposed to be compatible with RobotHub out of the box or is there a 64-bit image available I can flash?

                Thank you

                    Hi kohani ,
                    That explains the issue, so WiFi wouldn't be possible, except by eg. using a WiFi dongle. By default you don't need heatsink for the RPi, as also standard RPis don't have it. If ambient temperature reaches very high temperatures, then it might throttle the CPU to reduce the temperature. Stepan will clarify on RH issue.
                    Thanks, Erik

                        kohani Hello,

                        In regards to the RobotHub issue - 32 bit versions are indeed not supported, so you will need to flash it if you want to connect it to RobotHub. We would recommend the Raspberry Pi OS 64-bit Lite version. This guide might be of assistance.

                        Hope this helps!

                            Hi erik ,

                            Shouldn't it come with wireless capability? The store description mentions OAK-D CM4 integrates the Raspberry Pi Compute Module 4 with Wireless. I don't see an option for choosing wireless during purchase, so wondering if I need to exchange the one I received.

                            Thank you

                              Hi StepanKroupa,

                              I flashed the board with Raspberry Pi OS 64-bit Lite, installed dependencies and the depthai Python library, and successfully ran the RGB demo. Finally, I installed the RH agent, and the device was discovered inside RH, however, the status seems to be stuck at "Identifying". See attached screenshot. As a result or perhaps unrelated, the video preview brings up a modal "Waiting for a stream..." but nothing happens.

                              Please let me know if I missed something.

                                  kohani Hello again,

                                  Please go to the "Apps" tab in the sidebar on the left, Create an App, then go back to your Robot -> Perception Apps -> Install the new app. After it installs, click on the App and check the streams in Live View (on an RPI it might take up to 20 - 30 seconds for the streams to start). If the streams still don't work, please send the logs

                                      Hi StepanKroupa,

                                      Just to clarify, did you mean a blank app? If so, then install failed with the following output:
                                      Error: unable to start container "1d1df8f2c2ce39ab5506728f3442be71ca79d3f2550c232d0c4f31bc2c78d41d": crun: opening filememory.maxfor writing: No such file or directory: OCI runtime attempted to invoke a command that was not found

                                      Please see the screenshot for settings and output.

                                          kohani Hello again,

                                          I am sorry about this issue it is a known one - we have a fix for it but its not yet deployed. To fix it on your machine, please add cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1 to the end of the first line of /boot/cmdline.txt. After rebooting the CM4, this installation issue should no longer occur.

                                          Hope this helps!
                                          Stepan

                                              Hi @StepanKroupa @erik I got the OAK-D CM4 with a Tenda USB Wi-Fi dongle in the box:

                                              It shows no wireless LAN available and there are some issues/glitches with OS also, can I install official Rpi OS or is there any OAK-D flavor of OS available for fresh flash?

                                              CM4 on back is this:

                                                erik Thanks for this, the folder contains images for PoE version but mine is OAK-D CM4 is it same for both?

                                                Can I power this module with micro usb through USB_BOOT slot disabled?

                                                and any help on Wi-Fi dongle driver installation?
