IAR and CMSIS

[alberto110]

Can i directly replace New version of CMSIS with older one in the instalation directory ?

You can try, but you might need to change quite a few lines of code in order for it to compile depending how older the lib you have is from the lib you want to upgrade to. I had similar issues with a FreeRTOS example running old CMSIS and my implementation using newer, that I tried to mix together. I lost a couple of days before I fixed it.

orginal version is 2.0 new version is 2.1 .

Well, if I were you, I would give it a try. Just backup old files and replace them with new. Then make a few demo examples and see if it works, and if not, try and compare the differences between old and new and try to fix them if you can.
