It's probably your browser cache that needs flushing or try force reloading the page. If that doesn't work then I have attached the file you want that I just downloaded from the wiki.

Thanks Chris and Nigel.

I had been reloading the page, but I just tried it again right now and, what do you know, it's showing the 0.1.4 file. So I've downloaded it. Appreciated.

Magic Lantern 0.1.4 users be aware that if you shut down or let the camera time out in this version while you are in the menu mode, you may not get a complete shut down, and you will have to pop the battery out and reload it.

Also, when camera is shut down, on next reload you are back to defaults. Hopefully, in future version, Tramm will find a way to make your Zebra gain settings stick....

I haven't figured out where it is safe to write things in NVRAM. That's obviously a dangerous place to go scribbling since it might overwrite some other Canon settings.

Another step that I need to try is to open a file on "C:/", which appears to be some sort of in-memory filesystem. If it is also in the NVRAM, perhaps that would be a safe place to store all of our settings.

It would be awesome if, along with the firmware, we could put a configuration file on the CF card that we could load. That would help in multi-camera shoots.

Chris Hurd · June 24th, 2009, 09:56 AM

For what it's worth, I have absolutely *no problem* with having to manually set up a specifically called files / folder structure for each CF card that I'm going to put into the camera... in addition to copying ML to each card.

Jon, you come up with some of the best (and simple) ideas. That's perfect.

Chris Barcellos · June 24th, 2009, 10:09 AM

As I suggested before, with the small file size, one could keep a subfolder of various versions of ML, on each chip, and drag an drop the one with the settings into root before start up. I know with the variables starting to grow, this will get to complicated, but maybe kind of editable string for the user to set up on the CPU system, that automatically writes the wanted values into the version of ML.

Excellent! I'm glad to hear that a config file is doable.

One thing to keep in mind is forward compatibility. As new versions become available, we would want our previous config files to still be valid. And you probably don't want to write version converters, or burden the code with the reading of bunch of completely unique formats/versions. Unless you're designing Microsoft Word, of course. :)

Anyway, design that first config file with great care. You might have to live with it for a long time...

One advantage of being "in beta" is that it is sometimes ok to say "delete the config file and restart"...

I think we'll have a simple text INI style file initially, but ideally we would move to a script based setup. So at startup the Magic Lantern firmware would look for a autoexec.pl (or .py or .scheme or something) to initialize all the parameters. That way the complexity of configuration is moved out of the "hardcoded" C code and into an end-user editable format.

Chris Barcellos · June 24th, 2009, 12:13 PM

Sounds right to me ! By the way, I think in some situations we will want to turn off zebras, so that option should be there at some point..

Title speaks for itself. I have loaded to my Canon 5D Mark II, and after booting, go to the Picture Style button. There in small print on left center is area. You go up or down and adjust with the toggle.

I will be testing tonight, but this means a lot more to us, depending on what you are using to get sound to your camera....

Go Here :

Magic Lantern Firmware Wiki

Chris I am sorry if it is obvious, but how do I adjust gain and zebra?

For the truly adventurous, fool hardy and other mad men, the Magic Lantern 0.1.4 sources are now posted: Download Magic Lantern sources.

Even more than the pre-built and tested binary firmware images, these sources are potentially dangerous and you can damage your camera. There is no warranty of any kind on this software. There is no support implied. In fact, it is best if you pretend you never read this post and instead look at cute pictures of animals instead.

To build the firmware I'm using arm-elf-gcc 4.3.2 on Mac OS X and arm-linux-gcc 3.4.4 on Linux. Beyond that I can't make any promises of things compiling or working. You must also have mercurial, perl, make, binutils, etc. There is no support for cross compiling from Win32.

Due to copyright issues with Canon's firmware flasher, you must supply your own 1.0.7 firmware image if you want to build the ROM dumper. The only top-level Makefile target of interest is magiclantern.fir.

The sources are GPLed, but any commits to the main tree must be accompanied by copyright assignment.

Good luck and be careful.
