@JaredCJR : Is it possible to use upstream CMSIS via git-submodule instead of copying files into the current repository?

jserv commented 8 years ago

We can create a new directory named after "08-CMSIS", which represents for the portable version of "07-Threads" and multi-board support.

@jserv The CMSIS you mentioned does not include the vendor specific CMSIS(for peripheral). In the REAME:Porting Guide/STEP 2. , that CMSIS in the mbed is much useful than the previous CMSIS. However,it contains a lot of driver that we don't need. We only need ".h" for memory map. And the CMSIS need to remove some "ifndef" in order to avoid further "include" in peripheral part,which vary with vendor's implementation.

I think the git-submodule idea is not possible in this case.

The full idea I learnd from the MRI porting guide

I will create new PR for "08-CMSIS" later!

jserv commented 8 years ago

Affirmative! The major design principle of 08-CMSIS is to ease the porting efforts by means of CMSIS and/or mbed infrastructure. We can introduce some scripts to manipulate the headers and corresponding source files for OS HAL adaptation.
