emt's Introduction
emt-a61 Energia Multi-Threaded (EMT) Wiring Support https://gitorious.design.ti.com/emt This tree provide a multi-threaded Wiring lbrary implementation bases on TI-RTOS. To Clone this Tree ------------------ o you must already have a https://gitorious.design.ti.com account, then o clone the tree using git: git clone [email protected]:emt/emt.git ./emt To Contribute ------------- If you haven't already done so, create a personal branch with your name, for example, "me": git branch me git checkout me The "normal" development cycle: o make and test improvements emacs Control.c : o commit changes to your local repo git add src/apps/robot/Control.c ... git commit -m "improved ..." git add src/apps/robot/ti/drivers/wifi/WiFiTivaCC3000.c git commit -m "fixed ..." o push the changes from your local branch to the corresponding gitorious repo's branch git push origin me:me o to get copies of other's changes git fetch Weekly integrations: Your contributions will be periodically reviewed and merged into the gitorious repo's master branch. To ensure your contributions can be easily merged on the gitorious master branch, you must o get latest master branch from the gitorious repo git fetch o merge any changes into your branch git merge origin/master o push your local branch to the corresponding gitorious repo's branch git push origin me:me To Create a Gitorious Account ----------------------------- o download the git command line tools (Windows http://msysgit.github.io/) o create an SSH key: ssh-keygen -t rsa Just press 'Enter' in every question it asks and you will finally have your pair of keys under the folder ".ssh". For example, type "cat ~/.ssh/id_rsa.pub". That's the public key that you are required to copy and paste into your account on Gitorious. o browse to https://gitorious.design.ti.com and create an account using the public key you just created; copy the contents of ~/.ssh/id_rsa.pub to the specified text box. To Create a Gitorous Project ---------------------------- This tree is hosted on the Gitorious server https://gitorious.design.ti.com and was initially created on Linux and pushed to Gitorious as follows: cd <top of the initial tree> git init git add README src/ git commit -m "initial commit" git remote add origin [email protected]:emt/emt.git git push origin master Librarian repo creation ----------------------- The emt.git repo was created to "track" the repo maintained at gitoroius.ti.com and was created as follows: git clone --bare [email protected]:emt/emt.git emt.git cd emt.git/ git config remote.origin.fetch "+refs/heads/*:refs/heads/*" git tag emt-a00 git push --tags Note: xlibrary must be given read/write access to the Gitorious repo cloning of pushing any changes. This must be done via the Gitoroius web interface (blech!) To enable gitweb access: cd /db/sanb_public/home/git ln -s $TREES/emt/emt.git Librarian releases ------------------ Build this tree from Linux using standard ggentree/SM-MAKE/greltree except for the addition of a step to update the local emt.repo with the content from gitorious. # update local copy of the gitorous repo cd emt.git; git fetch; cd .. # clone the tree and merge/review user content ggentree -u [email protected] emt.git/ cd emt-a?? git merge origin/dr # build the tree SM-MAKE .clean SM-MAKE .all-files >& Make.log # update README emacs README git commit -a -m emt-a?? # release the tree greltree -m "something brief and meaningful" ======================================================================== ADDITIONS DELETIONS CHANGES ti.platforms.emt26xx ti.platforms.launchpad Rework ordering of section placements to not cause resetting of "." after DMA descriptors are placed. Allow either linker command file to be used for ROM or non ROM build flows. MRS

Feature Request: EMT Closure Available Features
As issue energia/msp432-core#40 concerns all EMT-supported boards, maybe this repository is more suited.
Here's an example:
MSP432 EMT on Energia 18 fails, even for the blinky example.

exit status 1
MSP432 EMT on Energia 19 succeeds to compile the SwitriggerLibrary
example.
Suggested solution
Add to the TI-RTOS closure a list of available and implemented elements, e.g.
#define EMT_HAS_SWI
#define EMT_HAS_TASKS
#define EMT_HAS_EVENT
#define EMT_HAS_SEMAPHORE
#define EMT_HAS_MAILBOX
#define EMT_HAS_TIMER
#define EMT_HAS_CLOCK
Two options:
- Either use
1
and0
to flag the implementation of an element...
#define EMT_HAS_SWI 1 // 1 = SWI implemented, 0 = SWI not implemented
...to be tested with #if (EMT_HAS_SWI == 1) ... #endif
- Or define the macro only if the implementation is done...
#define EMT_HAS_SWI // define = SWI implemented
// #define EMT_HAS_SWI // comment = SWI not implemented
...to be tested with #if defined(EMT_HAS_SWI) ... #endif
