initial ML version for 600D/T3i

[indy arm]

Hi,

Please find:
- an minimal version of ML that set the bootflag.
- Stubs and Consts files for "autoexec.bin" development

Thanks to Chucho for the very first test!

Most work has been done by Alex and assembled by me.
we used this tag as a starting point: https://bitbucket.org/a1ex/magic-lantern/changeset/93135f58ed93

Any developer for the 600D/T3i will be helped to port the 550d and 60d features.

Indy (who do not have a 600d ;-)

[arm.indy]

this is for Canon firmware 1.0.1, so upgrade first !

I installed this on my t3i, per the 550d instructions (using these
files). The ML hook installed (shows in firmware), but ML will not
launch when trashcan button. SD card made bootable with the macboot
utility, camera set to "P" to install, set to "movie" when trying to
activate.

same here, but so far i understoud its

"an minimal version of ML that set only the bootflag."

no other functions yet.

i have a 600d and i am free to test any versions :)

Hey I do some pretty in depth php programming, and while I realize
it's probably quite different from what you're working with, some of
the code looks very recognizable and like I might even be able to make
sense of it and pitch in. Is there a link to an SDK or something I
could use to help? I'd love to get involved and contribute...

[Chuchin]

Brain, I'm using the 550 build as a starting point, which can be
downloaded here https://bitbucket.org/hudson/magic-lantern/src you
have to update the 5d-hack.c file the new address that can be found in
the consts-600d.101.h. In the gui.c file keep the #include
"consts-550d.109.h" untill the 600d are confrim. In the makefile the
restartstart has to be update which is in the stubs-600d.101.S also
replace the 550d-empty.hdr with the 600d frimware, keep
magiclantern.lds entry.o 5d-hack.o stubs-600d.101.S version.o bmp.o
font-large.o font-med.o font-small.o config.o menu.o debug.o stdio.o
lens.o property.o propvalues.o gui.o chdk-gui_draw.o and try to
activate the other functions one at a time. You will have to rewrite
code as needed but not much.

gui.c from 60d can be used.

counter and queue offsets (0xc and 0x30 resp.) are the same.
struct is 0x1C38

600d is closer to 60d than 550d: same DryOS 2.3 version release #47

thanks for your help Chuchin!

Ok so where do I get the ARM dev tools/environment to follow up on
this?
Is it available on OSX or just Windows?
If I can get the hang of the codebase I might even develop a new
feature or two!

I only had success running the gnu arm compiler on Ubuntu using this:
http://magiclantern.wikia.com/wiki/Build_instructions/550D

Removing the need to use libc in the source (by replacing the needed
functionality from eg. bionic or uclibc) would make the building a lot
easier though imho.

[Alex]

Right now, the only dependency on libc is memset (and even this one is
optional; my_memset.c seems to work well).

[arm.indy]

if we execute this piece of code on the 600d, it should display some
video ram addresses:

int i;
unsigned int *bmp_ram_addr = bmp_vram_info;
for (i=0; i<2; i++)
DebugMsg( DM_MAGIC, 3, "bmp_vram[]=0x%08x, 0x%08x, 0x%08x",
bmp_ram_addr[3*i+0], bmp_ram_addr[3*i+1], bmp_ram_addr[3*i+2] );
unsigned int *vram_info_addr = vram_info;
for (i=0; i<3; i++)
DebugMsg( DM_MAGIC, 3, "vram_info[]=0x%08x, w=%4d, h=%4d, p=%4d, n=
%4d",
vram_info_addr[5*i+0], vram_info_addr[5*i+1],
vram_info_addr[5*i+2], vram_info_addr[5*i+3], vram_info_addr[5*i
+4] );
unsigned int *stateobj_disp = 0x23DC+0xb0; // see FF062CEC
SetBitmapVramAddress
DebugMsg( DM_MAGIC, 3, "stateobj_disp+0xb0[]=0x%08x,0x%08x,0x%08x,",
stateobj_disp[0], stateobj_disp[1], stateobj_disp[2]);

I just cloned Alex's branch from this revision
https://bitbucket.org/a1ex/magic-lantern/changeset/93135f58ed93

and included my diff for 600D / T3i in

so has anyone got the t3i with ML working ?

[Vincent Olivier]

Hi Indy,

I looked at both your code and the hudson original master (both
downloaded just a couple of minutes ago).

Your T3i branch seems to be missing some code from the main hudson
branch. Namely, when I search for the string "movie" in all the text
files, there is a "movtweaks.c" file that is returned in hudson's case
but not in your branch. I'm asking because this code contains
something that is of high interest to me possibly, the auto-restart
movie recording function, seen in the hudson movtweaks.c at line 313
(search for "movie_restart").

I'm looking to bypass both the 29m59s and the 4GB limits on movie
recordings. An auto restart whenever the movie recording is non-
interactively stopped will fit the bill for now.

So yeah, I'm just asking why is this code missing from your branch and
if you are planning on reincorporating it, or if I can do it myself,
if I'm on the right track, etc.

Regards,

Vincent

Hi!

The 600D branch is based on the 60D branch which is based on the 550D
branch which is based on the original master (5DmkII branch), but is
somewhat different as Alex is actively developing new features primarily
here. Each one has more or less differences from the previous one. If
looking for features you should first check the 550D or 60D branch, as
those contain the most compatible code that should more or less work on
600D too.

Hi,

When looking for the "movie_restart" in the t3i branch, it only shows up in the "debug.c" file whereas in the original one, there are around 10 files where it's a hit. So, I might want to import this code in. But I'd need a little guidance…

I'm totally new in this and it's really difficult to get a grasp on the code because the only comments I will find in there are dead lines that have been commented out. ;-)

For instance, everything of interest seems to arise around "call("MovieStart");" statements. I find "4a79d9 FA_MovieStart" in the "fa-functions.txt" file, but no further definition for that. Is that a lower level service in DryOS or something? Can it be overridden/looked at?

And even if I get the whole thing to compile and load on the camera (which seems feasible given the instruction set I found for Mac OS), I'm not sure I will be able to understand what needs to be done to have ML working on the t3i before you guys are done with it… Unless I get a crash course or something…

Anyways, I'm really into bypassing the recording time limits as per my other conversation here : http://groups.google.com/group/ml-devel/browse_thread/thread/9c2b9aece9e459fd

And I'm willing to give a couple of hours every week until we nail it for the T3i, conditionally to some intellectual support on the code structure. ;-)

Anyways, let me know.

Vincent

[arm.indy]

Hi Vincent,

The first thing is to activate menu and key events handling (gui.c).
The 60d code can be reused, but key events may differ a little bit.
the 600d is very close to the 60d, which must be taken as model for
the porting process.

[Vincent Olivier]

Hi Indy,

I'd be glad to look into it. I'm trying to compile the ARM toolchain now (from the current esden trunk). It currently crashes at "Configuring openocd-master" with

"checking Build & Link with libftdi...... configure: error: Cannot build & run test program using libftdi"

Contacted Piotr Esden-Tempski about it already.

I think I'm going to look for a version dating back from the time when the ML instructions for Mac OS on the wiki were developed, now.

While it's compiling, I'm looking at "gui.c", guessing that the actual changes need to be done in header file "consts-600d.101.h".

Can you confirm that you are now trying out event constants using "console_printf" (guess from commented out code), which, what, will output on the camera screen? If so, can we separate the workload so that we don't redo the work independently?

Still compiling ARM toolchain…

Vincent

[arm.indy]

follow the wiki to create your build toolchain
http://magiclantern.wikia.com/wiki/550d_dev

[Alex]

Hi,

Do not use other versions of ARM toolchain; use the ones recommended
on the wiki.
http://magiclantern.wikia.com/wiki/Build_instructions/550D

If you don't use console.c (i.e. just bmp_printf), messages will still
appear on the screen, but sometimes they may get erased before you
have a chance to read them. For the first time, I think it's OK to use
this approach.

To use console_printf, you need to include console.c (add console.o in
Makefile at ML_OBJS-y ). This will print messages on the screen; you
have to start it with console_show() first, because the menu is not
working yet. Also make "draw_event = 1" in menu.c.

Relevant pages:
http://magiclantern.wikia.com/wiki/Debugging_Magic_Lantern
http://magiclantern.wikia.com/wiki/GUI_Events/550D

Also see the 60D porting thread for more hints.

[arm.indy]

Vincent,

static void gui_main_task_60d() in
https://bitbucket.org/a1ex/magic-lantern/src/93135f58ed93/gui.c
should work "as is", because queue and counter are at the same offsets
as with the 60d.
other changes are handled in consts and stubs files for the 600d.

yes, buttons codes (BGMT_*) must be modified on consts-600d.101.h file

Alex knows this better than me.

Hi again Alex and Indy,

I recompiled the ARM tool chain from the script provided in the ML forum. Now, I'm getting this upon running "make" in the T3i branch of the code :

######## BEGIN

~/arm-toolchain/bin/arm-elf-ar cr libstdio.a lib_a-setjmp.o lib_a-strlen.o lib_a-strcmp.o lib_a-memcmp.o lib_a-memset.o

[ LD       ]   magiclantern

[ OBJCOPY  ]   magiclantern.bin

[ CC       ]   reboot.o

[ LD       ]   autoexec

[ OBJCOPY  ]   autoexec.bin

Notice: ../dumper/build_fir.py not found; will not build magiclantern.fir. It's okay.

Leaving magiclantern.fir unchanged.

stat: illegal option -- c

usage: stat [-FlLnqrsx] [-f format] [-t timefmt] [file ...]

make: *** [magiclantern.fir] Error 1

######## END

Previously, I extracted the 1.0.1 firmware from the Canon-supplied DMG file and renamed it to "dumper/600d_101.fir" I also put the "magiclantern.fir" from the T3i ML forum thread in the build directory.

So, not sure what to do from here. Do you guys have a clue on what I did wrong?

Thanks,

Vincent

I'm sorry. I read that already. I'm not sure what you are referring to exactly. If it's about the signature thing, I did place the "magiclantern.fir" in the build directory (see bottom of my previous message, after console dump). Is that where it's supposed to go? I'm not sure…

Vincent

[Alex]

It's okay, it worked. You only need autoexec.bin.

[Vincent Olivier]

OK, so I upgraded with the provided "magiclantern.fir". I now have "Firmware Ver. 1.0.1-ml-2011May29". I made the SDHC card bootable with MacBoot. I copied the provided "cropmks" folder and the "autoexec.bin" I just compiled.

But I can't seem to be able to trigger anything. Does the code now in version control do anything more than "set the bootflag"? How to I test "gui.c" from the camera? Or confirm that the autoexec.in has loaded properly?

Thanks again guys. I know this is basic stuff, but, well, I think I can contribute if I get these little steps done! ;-)

Vincent
