OAk-D-CM4 over Wifi (drivers)?

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

Thank you, StepanKroupa. It worked perfectly.

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:

Hi AnshumanFauzdar ,
You can use the standard RPI OS and then just install depthai on it (https://docs.luxonis.com/projects/api/en/latest/install/). We also provide precofnigured images (so they already have depthai & dependencies installed) here: https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/raspberrypi/
Thanks, Erik

Hi AnshumanFauzdar ,
Yes it should work for your cam as well, there isn't much difference.
The usb-boot is for flashing (emmc, see here), I don't think you can power the whole board through it. Does the dongle not work by default with newest RPI OS image?

1. Thanks for this clarification
2. Got it, if it would have type C or this boot_USB it would have been nicer to work in production environment. Is PoE supported because I can see pins labelled with PoE hat CT1, CT2, SP2, SP1, if yes where can I get it?
3. I have not flashed new OS yet, will try and update here.

Hi AnshumanFauzdar ,

2. Looking at the schematics I believe it should, just note that the SOM heatsink will be in the way, so you might need extension header (like this), so you'll be able to connect the POE hat onto the OAK-D-CM4.

erik Where can I get the PoE hat? Buy link will be appreciated. Thanks

erik Thanks!

erik I flashed with the newest RPi OS and still dongle is not detected, when doing lsusb, I am getting the list with the device in it:

Bus 001 Device 007: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch)

and I followed following post and I am getting on make step and errors are like this:

make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/6.1.21-v8+/build M=/home/cm4/Downloads/rtl8188gu modules

make[1]: *** /lib/modules/6.1.21-v8+/build: No such file or directory. Stop.

make: *** [Makefile:1895: modules] Error 2

Hi AnshumanFauzdar ,
Seems like drivers are needed, could you try following the tutorial here?

erik Hey, forgot to attach the repo in previous reply I tried the same repo, I am getting error on make step:

This doesn't look that straight forward.. We will grab the same wifi dongle and prepare a new RPI OS image that has drivers installed for this dongle.

erik thanks for the support, please share the process here also it will be useful for future reference also.

@erik Is there any update or you can arrange alternate WiFi dongle which works? I waited a long time for this!

Hi @AnshumanFauzdar ,
We apologize for the delay, we have released an updated RPI OS image (v10) here, could you try following the flashing tutorial here ?

erik I flashed twice, first time wifi was working but login was not working

Second time login is working but wifi is hit and miss.

By hit and miss I mean it shows connecting and sometimes connects:
