TI Stellaris Launchpad
Locked
|
Hi all,
I am interested in running eLua on a TI Stellaris Launchpad (http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=stellaris-launchpad&HQS=stellaris-launchpad-b). Can anyone kindly suggest how I can tackle this port? Should I start from the Kinetis port (https://github.com/elua/elua/tree/kinetis)? or perhaps from the STM32F4DISCOVERY port (http://wiki.eluaproject.net/STM32F4DISCOVERY)? Or perhaps there is a general template to base a port on? Thank you, Andres _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Neither. The Cortex M3 and M4 architectures are not that different, so I would suggest starting from the LM3S platform port and build on that (I don't know how much the TI support library has changed from M3 to M4 parts though). > > Or perhaps there is a general template to base a port on? No. Even if it was, I doubt it would be much help in this case, since the LM3S backend should provide a much better code base.

In reply to this post by Andres Molina-Markham
I have done a bunch of work on a port for the Stellaris Launchpad. Some other things came up so haven't gotten it posted on git yet (if you look in the archives you will see a little bit of discussion of this a month or 2 back). Got it to the point of compiling mostly (using Code Composer Studio), but haven't put together tool chain to compile it for real, or tried linking/running. What I have done is mostly adapting the LM3S code to the LM4F (handling differences in the peripherals, etc.) I did that before I found out that the big limitation will probably be the limited memory available on the launchpad. I would suggest that looking at how to trim the eLua memory footprint might be the first place you might want to concentrate on. Will try to post what I have done soon. > ----- Original Message ----- > From: Andres Molina-Markham > Sent: 02/19/13 03:34 PM > To: eLua Users and Development List (www.eluaproject.net) > Subject: Re: [eLua-dev] TI Stellaris Launchpad > > Thank you Bogdan, > > I will give it a shot. > > Cheers, > > Andres > > > On Feb 19, 2013, at 04:59 PM, Bogdan Marinescu <[hidden email]> wrote: > > > Hi, > > > > On Tue, Feb 19, 2013 at 10:49 PM, Andres Molina-Markham <[hidden email]> wrote: > > > Hi all, > > > > > > I am interested in running eLua on a TI Stellaris Launchpad (http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=stellaris-launchpad&HQS=stellaris-launchpad-b). > > > > > > Can anyone kindly suggest how I can tackle this port? > > > > > > Should I start from the Kinetis port (https://github.com/elua/elua/tree/kinetis)? or perhaps from the STM32F4DISCOVERY port (http://wiki.eluaproject.net/STM32F4DISCOVERY)? > > > > Neither.

Hi,
Ah yes. I found the thread and the comments about the limited amount of RAM on the stellaris launchpad. I'll start playing with it to try to reduce the RAM footprint.
