Building v0.7 with MMCFS for EK-LM3S8962 (SDC_SPI_NUM undefined)

[Tim Sharples]

Hi! I'm very much enjoying eLua v0.7.

Building v0.7 for EK-LM3S8962 with MMCFS enabled does not seem to build in MMCFS.

The problem appears to be that v0.7/src/platform/lm3s/platform_conf.h refers to SDC_SPI_NUM at line 191 which switches off BUILD_MMCFS. I guess it should be changed to refer to MMCFS_SPI_NUM (it works for me anyway).

All LM3S boards with SD will be similarly affected. One to fix on a rainy day?

Regards,

[Dado Sutter]

Thank you very much Tim,
   We'll take a look asap (no, it is not raining today here :)

Best
Dado

Yep, that's a mistake, and the correction you suggest will work.

I'll check in a fix to trunk shortly.

Thanks James,

Now I'm going to scratch my head a bit and see if I can update files in /mmc/ using only the Lua command line (and ultimately edit files on my SD card while it is still in place in the EK-LM3S8962, but that's another story).

You can't do this right now. And I don't think you'll be able to edit the files on your SD card while plugged in an eLua board anytime soon, but with the introduction with RFS all we need is a shell 'copy' command. Then the flow becomes quite easy:

1. edit the files on your PC with your favourite editor
2. use the RFS on the eLua board to access them
3. when you're done, use the yet-to-be-written eLua "copy" command to copy RFS to SD.

I think this is a very practical use scenario. Even more practical IMO than being able to edit files on the SD card from your eLua board. Definitely much easier to implement :)

Best,
Bogdan

I believe he was meaning using just eLua to modify files on the SD
card, which should work just fine.

What we don't currently provide a recommended path for is remotely
editing files on the mmcfs filesystem.

You could probably edit files on mmcfs remotely over luarpc, though
I've not tried this.
