I think I have the same problem and I want to be sure of exactly what I need to do (I don’t know if there is a step-by-step tutorial…).

I boot with a USB-C network adapter on an HP Elitebook. It finds FOG, I have the menu, I choose to deploy an image, and then I get this error message:

Is this the problem in question?
If so, what exactly should I do? I see (link @FlorianLenz ) that I need to replace two files with the new ones, then run the .sh. But isn’t that dangerous for other network boots?

Thank you in advance for your help.

@c4c @george1421 I can assure you that there should be nothing special that build.sh is pulling or doing. While we have different branches like master (latest official) and dev-branch (development) in the fogproject repo this is not the case in the fos repo. I always use fos master to build stuff. If I do really fance new things I create short temporary branches but merge those into master again as soon as things are ready to go.

One thing I just noticed in George’s desciption is using make -j4 to build. The official manual states that “Buildroot does not support top-level parallel build” (reference). Though I can’t really think of this causing the problem described.

If you work more on this you should also read this part of the manual: https://buildroot.org/downloads/manual/manual.html#full-rebuild - e.g.:

When a package is removed from the configuration, Buildroot does not do anything special. It does not remove the files installed by this package from the target root filesystem or from the toolchain sysroot. A full rebuild is needed to get rid of this package.

Final update: Got everything working! The monitor not waking up after sleep was fixed by adding in some extra graphics drivers to the kernel and we’ve found some solutions to wiping difficult machines (like Lenovo’s) which normally force you to use tools built into the UEFI or a special Lenovo wipe program that only works on certain models and asks you to confirm 5 times and gives you a random generated key that you have to enter in after a reboot. As a note, even parted magic fails to wipe Lenovo drives.

Anyway, thank you @george1421 you’ve helped me to learn a great deal and enabled our success in this.

@sebastian-roth Thanks for the swift response, looking closer at the fog image files this is exactly the file I will need to modify! From our perspective it would be great to have an audit trail for hardware built in to future versions, but I understand if there isn’t much demand for it, though slightly surprised as it seems useful to me for a whole variety of reasons outside of our specific use case (in which it is required!).
