Can you show us how to run it with sandbox?

To understand the situation, I tried running the test using v2025.10.

     ./test/py/test.py --bd sandbox   --build  -k efi_fit
     ./test/py/test.py --bd sandbox64 --build  -k efi_fit

The test was skipped as follows:
     test/py/tests/test_efi_fit.py::test_efi_fit_launch SKIPPED (.config feature "generate_acpi_table" enabled)

After disabling ACPI, the test failed with the following error
and could not be reproduced.

     => /u-boot
     Bloblist at 100 not found (err=-2)

There might be differences in the environment or procedure,
so please let us know if you have any tips.

Thank you,
