Porting ML to XSi (450D)

[LTG2004]

Hey Ant123, could you please update those download links as i would like to test this build.. They seem to be broken

[gunny2k6]

was lucky enough to be given a 450d .. started doing google found this an updated 450d from 1.04 to 1.09 (arg when u can find it lol) then 1.10 (had to flash from eos util on pc) and gave your test files ago and it works! OK not much you can do but loads magic lantern menus !! .. I know this camera is so old now and be awesome to have more features but I guess like the most of magic lantern seems to be dead or lack of devs 😔

removed it from my sd card via format option and just stock canon again as lack of being able to do really anything with this so no point leaving it running.

I'm also behind porting this, as I'm also running the 450D/XSi and don't mind experimenting. Also can help by dumping and building if need be, although I don't know my way around too much code, I can at least be a guinea pig.

Tried using your files but camera only flashes LED when ML450D110.fir is the only .fir file on the card.

Also tried to put original 1.1.0 firmware on the card with your fir. I can select ML450D110.fir and confirm the update and get the error message.

I'm I missing something?

Thanks

Read the FAQ first...

Couldn't get it to work but managed to get it to work with EOScard software.

I think that there is huge potential for porting ML to XSi/450d because a lot of people use it as a 2nd camera. The intervalometer works as you said.

This thread needs more exposure and more devs joining in.

I have tried it on my 450D and it doesn't seem to work. It is installed but I can't seem to be able to load the ML menu up, Also it messes up the live mode, it flashes strange text.

When I press bin buttom this is what show up, then it crash and have to remove the battery to restart. I pressed Set and nothing happened.




I do have 1.1.0 firmware installed. Is there a different region of 1.1.0 firmware?? My camera is UK Version.

Many Thanks

Mike

Managed to emulate the 450D GUI in QEMU, and also ran some tests on Ant's build:



Animation (click to zoom):



Emulation log

Canon menu screenshots (without ML loaded):


Besides the not-so-impressive feature set, I have a few questions:

- On the actual hardware, do the fonts look as bad as in the following screenshot?



- Do the colors in the menu customization mode really look as radioactive as these?



- Does the "ETTR ETTR ETTR ETTR" message show up on actual hardware as in the above screenshot?

Another surprise: if I compile ML from the vxworks branch (here), it doesn't boot correctly. When trying to compile from Ant's repository, changeset b05d7ea7f486 does not exist (did I misread the screenshot?) and his vxworks branch doesn't work either (emulation log - it gets stuck on initial screen). Compiling from latest changeset from Ant (c700f92) gives the same result (stuck on initial screen, with LED turned on).

Unfortunately, I did not have this commit when Ant posted his build - that would have embedded his local (uncommitted) changes in the executable file - so I'm unable to re-create his binaries from the current sources.

In any case, continuing the ML port on VxWorks models just got easier by an order of magnitude - or maybe two

Yes, if you are talking about ML Prefs menu.

Compiling from latest changeset from Ant (c700f92) gives the same result (stuck on initial screen, with LED turned on).

Confirmed - works with gcc-arm-none-eabi-4_7-2012q4 (without requiring the FIO workaround).

BTW - address 0xFFD65490 doesn't seem valid for 450D - did you mean 0xFFD237F0 ?

Does that mean not all these patches from disable_cache_clearing are actually required for booting?

Yes. There was wrong address 0xFFD65490.
But it doesn't help to create working binaries using modern GCC.
Only gcc-arm-none-eabi-4_7-2012q4 generates binary which doesn't stuck.

I don't know. I just found the same opcodes based on 40D port.

should not matter i Had 450D working with it ...i m in UK.... but have since traded in the 450D ...got as latest i could now on 77D (love it or hate it) not looked back i really like it as a huge leap forward. ye could get better but its what i wanted so
