So line 867 of SecMain.c has:
UINT8 *Src, *Dst;
which appears correct to me, so I believe that is an issue with the tool?

I'm trying to run this tool on my Ubuntu installs (both 18.04 and 20.04)
and it consistently fails trying to execute a git command:
$ python3 BaseTools/Scripts/EccCheck.py
usage: git [--version] [--help] [-C <path>] [-c <name>=<value>]
[--exec-path[=<path>]] [--html-path] [--man-path]
[--info-path]
[-p | --paginate | -P | --no-pager] [--no-replace-objects]
[--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]
These are common Git commands used in various situations:
start a working area (see also: git help tutorial)
clone Clone a repository into a new directory
init Create an empty Git repository or reinitialize an
existing one
work on the current change (see also: git help everyday)
add Add file contents to the index
mv Move or rename a file, a directory, or a symlink
restore Restore working tree files
rm Remove files from the working tree and from the
index
sparse-checkout Initialize and modify the sparse-checkout
examine the history and state (see also: git help revisions)
bisect Use binary search to find the commit that
introduced a bug
diff Show changes between commits, commit and working
tree, etc
grep Print lines matching a pattern
log Show commit logs
show Show various types of objects
status Show the working tree status
grow, mark and tweak your common history
branch List, create, or delete branches
commit Record changes to the repository
merge Join two or more development histories together
rebase Reapply commits on top of another base tip
reset Reset current HEAD to the specified state
switch Switch branches
tag Create, list, delete or verify a tag object signed
with GPG
collaborate (see also: git help workflows)
fetch Download objects and refs from another repository
pull Fetch from and integrate with another repository
or a local branch
push Update remote refs along with associated objects
'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
See 'git help git' for an overview of the system.
Fail to run GIT
ECC tool detect error
I've also tried specifying -1, a commit id, etc., but the same thing happens.
Has this been run/tested on Ubuntu? Is there something specific that needs
to be done in order to run this tool?
Thanks,
Tom
