Hi @JackChenHR , I checked https://openocd.org/doc-release/doxygen/patchguide.html#stepbystep this page, you can take a try.

@Alan-19950616 Please provide a step by step example later to check the patch style, not just the link I provided.

Hi @JackChenHR, here is the script you can check your commit patch

You need to install patchutils perl

# since you have commit two commits, this diff is  HEAD~2 , if you have more commits, such as 4, change to HEAD~4
git diff -U20 HEAD~2 | filterdiff -x "a/src/jtag/drivers/libjaylink/*" -x "a/tools/git2cl/*" -x "a/.github/*" | ./tools/scripts/checkpatch.pl --no-signoff -
# then you will be able to see style check output in command window
