Image shell command not supported

[Ryan Harkin]

When UEFI runs, it attempts to autorun the "startup.nsh" script. This script contains the command "Image <params>".

However, "Image" is not a valid UEFI shell command, so it an error is reported, thus:

"Error reported: Unsupported"

[Leif Lindholm (leif-lindholm)]

Is this script actually contained within the UEFI image?

If not, this bug should be raised against whatever generated filesystem is being used.

[Ryan Harkin (ryanharkin)]

The script comes from the filesystem, yes.

It is reading the file in the boot partition, EFI/BOOT/startup.nsh. This file gets copied into boot when linaro-media-create is run. It either comes from the rootfs or more likely from the "uefi-image-startup-nsh" package, I'm not sure of the mechanism.

Fathi tells me that he got the script from Roy. I'll subscribe him to this bug.

[Fathi Boudra (fboudra)]

the startup script is also documented on the wiki in several places. It's used for automation to avoid going through the interactive shell.

I'm fine to update the script to whatever is appropriate. Getting rid of it will be painful because it will force LAVA users to write the interactive shell sequence needed.

"Image" isn't a shell command, but rather the name of the EFI application that is being run - in this case it should be a kernel built with the EFI stub.

I have seen this error message in 3 different situations:
1) The file trying to be run is not an EFI application
2) The EFI application is of a different architecture (arm32 vs arm64)
3) Something wrong with the EFI header. We shouldn't be hitting this now, but during development I saw this when I didn't have the header right.

In this case that this is failing, have we confirmed what kind of file "Image" is? I think we'd get a different error message if the file was completely missing, so I think something was there with the right name.

[Ryan Harkin (ryanharkin)]

Well that explains it!

Of course Image isn't an EFI application! It's a regular kernel. And if
someone gets around to adding efistub to linux linaro, surely Image would
still not be an EFI application and there would be another file in there
that had the stub? (ie. we'd have both a regular kernel Image file AND an
EFI stubbed kernel)

There is no need for a separate non-stub image, even if I wasn't
throwing the built-in Linux loader out the window.
The stub image is still a valid image for loading in that other way.
