I have referenced the thread at: MacBook Pro camera not working on Ubuntu 18.04

It lists the following steps:

cd /etc/local/src
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie/firmware
sudo make
sudo make install
cd ..
sudo make
sudo install
sudo depmod
sudo modprobe -r bdc_pci
sudo modprobe facetimehd

I had the camera working, but forgot what I did. After an update, the camera stopped working.

I just followed the above steps except for the sudo install didn't work, so I did sudo make install.

I am now getting the following error when I try to sudo modprobe facetimehd:

wayne@MacBookUbuntu:~/Downloads/bcwc_pcie$ sudo modprobe facetimehd
modprobe: ERROR: could not insert 'facetimehd': Exec format error

Also is there a way to make the change permanent once fixed?

  • Update: It works. Apparently all the steps above work if you substitute sudo make install for sudo install. I rebooted and did a fresh download and the steps worked. I had been trying to save myself a step by using the old download.

    This question just gets worse and worse all the time and I'm starting to believe that the continual deterioration is inevitable. I tried to reject a previous conflicting edit, but I didn't succeed because two other editors overrode me and accepted it anyway. You wrote in the 5th paragraph that sudo install didn't work (obviously not) so what's the sense of degrading the original source except to purposefully create confusion? More importantly sudo make command is a nightmare from a security point of view. The correct command is make without sudo.

  • At this point your question is so full of errors that I can't fix it, because it's your question and I don't want to vandalize it. It's quite the opposite in fact. The easiest thing for you to do would be to visit the revisions page and rollback your question to a better earlier revision. One mouse click and you're done. I tried to prevent this disaster from occurring but unfortunately I didn't succeed.

For anyone who runs into this in the future, you need to run a make clean on both the facetime firmware and bdc_pci. So...

cd facetimehd-firmware/
make clean
make
sudo make install

cd ../bcwc_pcie/
make clean
make
sudo make install

sudo depmod
sudo modprobe -r bdc_pci
sudo modprobe facetimehd
sudo vim /etc/modules

then make sure that facetimehd is still written into your modules file.

Hope this helps!
