Many thanks for the quick answers. I followed the instructions from the
chipsec-manual.pdf of chipsec-1.5.0. In my first test I used python version
from chipsec-1.5.0 (chipsec_uefi_x64.zip) and UEFI-Shell from edk2 release
includes a precompiled UEFI-Shell binary which I used
(edk2-edk2-stable201903/ShellBinPkg/UefiShell/X64). With this setup I got
OSError: [Errno 22] Invalid argument: 'FS0:FS0:chipsec'
Can you tell me your working setup (UEFI-Binary and pyhton version)?
