how to download lua files?
Locked
|
I have downloaded the eLua binary to a development board (ET-TM32 STAMP). This all worked fine. I can use the shell to do some interactive Lua programming. I then used "recv" command to download (via XMODEM) and execute some sample programs (e.g. info.lua). This also works correctly. But here is my question - How do I download a lua file so that it stays in flash on the target board. The "recv" command simply downloads and executes. When I do a "ls" command, the file is not in the /rom directory. How do I get a file onto the board so that it is permanently stored in the flash file system? I know there must be a simple answer but I can't find it on the web site
documentation. Thanks Henri _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Hi Henry,
You can use the web builder to put files no rom too (http://builder.eluaproject.net/web/start.lua?control=user&act=index).
If your board have a sd card you can copy your files using a PC directly or use the commad "recv /mmc/file.lua" but in official eLua binary (version 0.8) this command not work correctly only master git version works (https://github.com/elua/elua).

Hi Bogdan Thanks for your reply. Basically all I want to do is create a lua script program, and download it to the target board so that the target board executes the program when it is reset. If I understand your reply and the documentation on line, the only ways I can download the new lua script for running on the target board are 1. use the recv command (but this doesn't store the program on the target) 2. re-build the binary incorporating the program and send the whole lot to the target (messy and time consuming) 3. use a local SD/MMC card (my target doesn't have one) 4. Use remote file system
(awkward and won't allow the board to execute. Is the above correct?

To do this, you need to write your program into "autoexec.bat" on some device. You have no writable areas on your target device; neither eLua not the eLua shell are currently able to reprogram the board's flash memory. In theory it is possible; it is just a small matter of programming in C and would certainly be a Good Thing.

Use a board with SD card, like the Mizar32 simplemachines.it/mizar32 If you use the Go@ (GoAT) IDE, while developing you can download and run the program by pressing a single button (F5, is it?) then when the program is right just download it to autorun.lua on the SD card. Does it get any easier? :) M _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Perhaps I should implement a quick&dirty FS for this kind of stuff ... A full R/W filesystem on the internal Flash has to fight a number of limitations on various devices, but a more restricted R/W FS shouldn't be that hard to implement.

Bogdan Even a "quick and dirty" file system would be a highly useful addition if it would allow a user's program to be downloaded easily to the target board. (To Martin) - Yes, I am aware that if you have an SD card on your target board (eg Mizar32), then this is not a problem - see point 3 in my original post. However, many of the target boards listed on the eLua's website do not have SD cards. I became aware of Lua while programming Celestia. It seems an interesting and efficient language, and I would like to use it in embedded applications. Being able to download a user's program is a pretty important functionality to add, especially since there are so many alternative boards one can use. BTW - by the time I add freighting outside Europe, I can buy 2 or 3 Arduino's or R Pie's for the price of a Mizar32.
