How to access the UEFI Shell?

GMNGMN New Member Posts: 9

I have a UP2, recently updated to BIOS UP-APL01 R5.0 (UPA1AM50).

It reports compliancy with UEFI 2.5; PI 1.4

However, I cannot seem to get access to the UEFI Shell. The setup BOOT options do not even have a menu item for selecting boot to the internal UEFI Shell, so what do I need to do to gain access to the Shell?

    I just found out that F7 will open a different menu that allows selection of the UEFI Shell. I had been pressing ESC to enter setup.

    That said, my OS loader still cannot access ShellProtocol.

    status = pBS->LocateProtocol(&guidShellProtocol, NULL, (void**)&pShell);

    status 14 - EFI_NOT_FOUND

    on UP Squared UEFI shell is not present, you would need to add a EFI application that will boot from USB with EFI Shell.

    You can find that application inside the BIOS update packages for UP Squared in our download section
