I had mdk470 installed & on updating to mdk470a, do not update it . The "about uvision" still shows v4.70.0.0.
I also uninstalled the software & then install but no help????
Yes - it does.
I seem to remember a post recently on this subject stating that the only difference was in a couple of help files - nothing changed in the tools themselves.
Doesn't the release note basically suggest it's the same compiler, with a slight fix to the installed documentation?
