Followed installation instruction from Wiki and from this site before. Always worked very nice. Now it stopped working and reinstall does not help either.

seems to be the same as here? https://github.com/patjak/facetimehd/issues/35

aliris-schmidt commented 2 years ago

Tried it again on a clean install of Ubuntu 21.10 5.13.0-28-generic MacBookPro11,3

Made every step of Firmware extraction and then Install script but the camera won't work.

I also get this error on sudo modprobe facetimehd.

modprobe: FATAL: Module facetimhd not found in directory /lib/modules/5.13.0-28-generic

Which I can't explain because as mentioned it is a new system no updates etc.

Just installed MacOS on an external drive to check if the camera works there. The camera is not recognized in the systems report. Dont know if that is an hardware error.

patjak commented 2 years ago

Hi All I can tell from the log is that the camera is not "booting" after the firmware is loaded. But as you say, if the camera is not working in MacOS then I suspect it's not an issue with our driver.

jplx commented 2 years ago

I have used this driver successfully on Macbook Pro running Gentoo Linux. However, it failed recently because apparently EAPI 5 is not more supported. I tried to modify to EAPI=6 in the ebuild file but it fails the "source prepare" step. It seems that it does not even fetch and unpack when EAPI is set to 6. Would it be possible for you to update both ebuild files to EAPI 6 or 7? The files are bcwc_pcie-9999-r1.ebuild and apple_facetimehd_firmware-1.43.0-r1.ebuild. Thank you in advance.

jplx commented 2 years ago

I was able to make it work with EAPI7 and the attached ebuild. It requires to download de bcwc_pcie-master.zip file into the DISTDIR directory defined in /etc/portage/make.conf It also requires to add the following FEATURES in the /etc/portage/make.conf FEATURES=" -sandbox -userpriv -usersandbox" As I am new to ebuild, this looks like a hack but it works on my Macpro. Your comments and corrections would be greatly appreciated.

bcwc_pcie-9999-r2.ebuild.txt

patjak commented 2 years ago

sorry, I don't know anything about ebuild. You need to ask whoever is maintaining the Gentoo package. I'm closing this issues since it seems to be about broken hardware.

jplx commented 2 years ago

OK. Thank you for letting me know.
