AARCH64 FVP build crashes when shell script executed

[Roy Franz]

When attempting to run a shell script using semihosting, I get the following error:

Roy - can you reproduce this on recent builds?

[Leif Lindholm (leif-lindholm)]

Ryan just reproduced it, so he can have it :)

[Roy Franz (roy-franz)]

Yup, I can reproduce it on the 2014.04.

Olivier had fixed a couple of semi-hosting bugs that I thought could be related to this:
FYI, we fixed the AArch64 semihosting issue. You will need these two patches:
- ArmPkg/SemihostLib: Made arguments 'native' size (SVN rev15389)
- ArmPkg/SemihostFs: Various fixes for the file system (SVN rev15390)

But those appear to be in 2014.04, so it seems to be something else.

[Roy Franz (roy-franz)]

Ignore the above, I was running a different binary image than I thought....

[Roy Franz (roy-franz)]

This seems to be fixed in the 2014.04 release - I am unable to reproduce it there.

[Ryan Harkin (ryanharkin)]

With the 14.04 OpenEmbedded release (which is using an old UEFI binary) I am able to reproduce the problem where shell crashes when attempting to run startup.nsh.

Next, I'll try with the Linaro EDK2 UEFI binary, wrapped into the latest Trusted Firmware.

[Ryan Harkin (ryanharkin)]

OK, so the latest Linaro EDK2 binary / fvp-pre-boot no longer crashes.

However, when running startup.nsh, all is not smooth:

Press ESC in 1 seconds to skip startup.nsh or any other key to continue.

[Roy Franz (roy-franz)]

Ryan - I think the error you are seeing should probably be a new bug, and this one closed, as it seems that what you are seeing is the EFI stub not executing.

Does the command in the startup.nsh execute properly if typed at the command line?

[Ryan Harkin (ryanharkin)]

Very true, this is a completely different bug now.

The "Image" command isn't present in this shell, that's the problem. If I run "Image" with or without parameters, it reports the same problem: "Error reported: Unsupported".
