I need to refer to the Architecture Reference Manual.
But there are several versions to choose as the link below, I want to know the guideline or the difference of each version.
Isn't there a revision history in each document?
It's generally best to use the latest revision, unless you have a specific reason to use a different revision.
And, if you did have a specific reason to use a different revision, you would surely know what revision you needed ?
I didn't find a revision history, but only a list of known issues for many revision.
It seems so details and also need to download for every versions.
You can check it with the link above.
And the revision name looks like "G,a" "A,j", I'm not sure which one is the latest one.
For example, armv8m architecture reference manual revision "A,j" only has 1.3k pages, but the revision "G,a" has 8.5k pages.
