I didn't take a look before, but essentially the one main thing we'd
like for people to do when making their own public copies with modifications is to use the GitHub fork button so that it will keep your public copy connected with ours so that if there are modifications on your version it will show up here: https://github.com/elua/elua/network It looks like Nuccio's version is doing so. Doing this is as simple as following the instructions provided by GitHub (pretty much initiated by going to https://github.com/elua/elua and clicking the "Fork" button), and will make it easy to allow us to pull changes back in when they're ready to merge back into the main project (as has been mentioned before). -jsnyder On Sun, Mar 13, 2011 at 8:28 AM, Nuccio Raciti <[hidden email]> wrote: > good, thanks. > > Il giorno dom, 13/03/2011 alle 10.25 -0300, Dado Sutter ha scritto: >> >> >> On Sun, Mar 13, 2011 at 08:57, Nuccio Raciti <[hidden email]> >> wrote: >> Hi Bogdan, >> >> I made the GitHub fork, now a my project >> https://github.com/nuccioraciti/eLuaWebServer >> is there. >> >> Regarding the network support for AVR32, I can prepare a patch >> file or >> if you prefer I can use the great GitHub (in which case I >> might need >> help). >> >> Let me know. >> >> For projects and code forked from other repos, please take a look on >> github's concept of "Pull Request" at >> http://help.github.com/pull-requests/ >> >> >> Nuccio >> >> Best >> Dado >> >> >> >> >> >> >> _______________________________________________ >> eLua-dev mailing list >> [hidden email] >> https://lists.berlios.de/mailman/listinfo/elua-dev >> > > > _______________________________________________ > eLua-dev mailing list > [hidden email] > https://lists.berlios.de/mailman/listinfo/elua-dev > -- James Snyder Biomedical Engineering Northwestern University [hidden email] PGP: http://fanplastic.org/key.txt Phone: (847) 448-0386 _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Doing this is as simple The only other work at github I know of (from Marcelo Politzer) is also based on a fork. Other eLua-based applications exist at github (ex: Thiago Naves) and do not always need to be forks of the "main" project if they are, for example, Lua code applications. I think we all have a lot to learn with the github way of living and we seem to have started well. -jsnyder Best Dado

Hi,
I did a GitHub fork in order to push eth support: https://github.com/Mizar32/elua ... but it doesn't work using the "-Os" (the standard one for eLua) optimisation, so it needs further investigation before the delivery. Has anyone had similar problems?

Thanks. How do I test this? I was hoping for the "net" Lua module (as implemented on lm3s platform) but doing the obvious copying of lines from lm3s/platform_conf.h into avr32/MIZAR32/mizar32_conf.h and enabling anything that uses the net module, such as BUILD_CON_TCP or the NET module, still results in the compilation error src/elua_uip.o: In function 'elua_net_send': ...

After a deep investigation, I discovered that the problem disappears building just "elua_uip.c" with no "-Os"
("-O2" or "-O3" are OK) nuccio > Hi, > I did a GitHub fork in order to push eth support: > https://github.com/Mizar32/elua > ... but it doesn't work using the "-Os" (the standard one for eLua) > optimisation, so it needs further investigation before the delivery. > Has anyone had similar problems? _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Eth support for AVR32 - resolved the "-Os" issue

In reply to this post by Martin Guy
The problem was related to the structure "elua_uip_state s" (**) that
should have been declared as "volatile". Ciao, N (**) line 279, file elua_uip.c, function elua_uip_appcall().

Hi,
what about an eLua simulator: 1- with the network support (using a TUN/TAP device http://en.wikipedia.org/wiki/TUN/TAP). 2- running as a user space linux application. 3- using the linux FS as /mmc /rom file systems. is someone interested? nuccio _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

really?
I thought we should restart the PC for every run. the "sim" target is different of "i386" one?

Last year, Thiago Naves and Marcelo Politzer were also experimenting with Proteus (http://www.labcenter.com/products/vsm_overview.cfm), trying to find a suitable target to embedd eLua. It would be great to have an eLua simulator on this kind of environment, as it already has interesting views and debug tools for the peripherals and even for simulated externally hardware connected to the MCU. As it has happened to eLua on the real world, I hope it is just a matter of time that new and larger (RAM & ROM) MCUs appear on the Proteus supported set. ciao, Best
