Tried to use fast SD Card - Sandisk Extreme Pro 95MB/s (UHS-I U3 V30). CHDK benchmark on Digic6 camera writes at 70+ MB/s.

On 450D ML benchmark in playback mode writes at 19-20 MB/s. The theoretical limit is 48MHz / 2 = 24MB/s.
Can't display benchmark results in LiveView mode because canon code refreshes the bitmap buffer continiously and ML texts are flickering or disappear. How to fix it?

Now MotionJPEG recording is more stable at ~29.7FPS (dual write buffering - 2x8MB).
But frame drops still occur when the frame size exceeds 400kB for a long time.
In some very spetial situations frame size can exceed 700kB. For example: https://i.stack.imgur.com/YbUvO.gif

The experimental build is there

Hi Ant123

I never any flickering on 40D, not even on the early version, but if you have flickering the buffering system is'nt working correctly, might be due to incorrect WINSYS_BMP_DIRTY_BIT_NEG address. If that one is incorrect the BMP_LOCKS in dialog_test.c will not work, and that might result in flickering. Without locking canon is free to redraw.

That is really interessing, too bad I don't have time atm to implement your module on 40D, maybe after summer holiday.

You need only modify lines 559, 560, 715 and 755.

Good day. tell me on the latest version of the magic lantern is the focus peaking function implemented? moved from film and got used to manual fixes. and this function would help me. only she is needed.

Not implemented on 450D.

Out of curiosity, does this port include the patch manager stuff? I'm wanting to use ML to help with trying to circumvent the SD Card write lock issue on mine (it shows as being set to lock no matter what, and not had any luck getting it to show otherwise so far), and I saw a1ex had a method for circumventing the check with ROM patching that required the patch manager.

Damiano · « **Reply #106 on:** August 10, 2020, 01:20:02 PM »

Hello,
I'm trying to find the STATE objects of the 450D. In particular i'm trying to find the address of SCSState and SSSState.
I'm using this procedure on qemu as a1ex said : https://www.magiclantern.fm/forum/index.php?topic=17969.msg196010#msg196010
but the first part of the code doesn't return nothing.

Code: [Select]

./run_canon_fw.sh 450D,firmware="boot=0" -d calls |& grep --text EvfState

Any idea why the code doesnt't work and how can find SCSState and SSSSate for this camera?
Thank you,
Damiano

Damiano · « **Reply #107 on:** August 15, 2020, 06:43:30 PM »

I was able to redo the procedure of a1ex using FWState instead of EvfState but the SCSState and SSSState are not present in the final result. Does anyone know what's the name of SCSState and SSSState for this camera?
Thanks.
Damiano

Hi all.
I am new to this forum and I appreciate the enormous work that you are all doing.
I am trying to install ML on a 450D.
When trying to download the BITBUCKER links give an error.

Could someone post a link with the latest version that works?
Thank you very much

Im new to this and my 450d has the 1.0.4 firmware version, does anyone have a WORKING link for 1.1.0? most of the links i found dont work or arent trustworthy
And what exactly are the features for the ML for the 450D, I dont know everything about this

Which of these do i need to download? because i got 3 .FIR files, ML450D110, ML-setup and e5kr4110.
The last one is the firmware update for 1.1.0 and not one of the others works to get ML on my 450D, I constantly get the error 'update file error please check the memory and reload the battery and try again'

kitor · « **Reply #113 on:** December 30, 2020, 07:38:45 AM »

First update to 1.1.0, then use Magic Lantern files.

Ant123 · « **Reply #114 on:** August 07, 2021, 08:09:55 PM »

I uploded the source code and the latest build to bitbucket.
But the modules can't be built because of missing the ".hg" folder. How to fix that?
Motion Jpeg movie recording is still experimental. It is limited to the SD controller speed. Maybe there need to increase somehow the compression of JPEG frames.

names_are_hard · « **Reply #115 on:** August 07, 2021, 09:09:10 PM »

Looks interesting, but it's hard to understand because there is not much context. This is a fork of some other repo? Which one? The commit history has lost everything from wherever it came from. It's not forked from mine because platform dir doesn't have any Digic 6, 7, or 8 cams. It would probably make more sense to have these changes on a branch of an existing repo, so that history was more meaningful.

You have a .gitignore file at top level, but official ML is hg managed - that's why you're getting these errors. You've probably taken this source from some git managed repo? The build process expects to use hg tools at a few places. Personally I think making the build process dependent on the source control system is not a good idea, I removed this in my repo so you might be able to adapt those changes:
https://github.com/reticulatedpines/magiclantern_simplified/commit/4a29a347f29276d4bec0876412cec4bb12b5a28c
https://github.com/reticulatedpines/magiclantern_simplified/commit/3163d41cee35fb54b4308e1f32318ff87de53645

Those changes might not cover everything you need, it was over a year ago and I wasn't very familiar with ML code yet, changes are more likely to be messy. Check commits around the same time.

Ant123 · « **Reply #116 on:** August 07, 2021, 10:11:08 PM »

This source code came from the official ML bitbucket repo last year before they removed all mercurial repos.
It contains my 450D related changes. Some code was taken from heder's 40D project.
But there was no changes since summer 2020. I was trying to convert mercurial to git locally but without success. Maybe I am wrong but it's strange that bitbucket do not provide mercurial to git conversion like github doing it (AFAIK).

names_are_hard · « **Reply #117 on:** August 07, 2021, 11:44:55 PM »

Okay, in that case definitely look at the commits I linked. ML does shell commands in various places that explicitly call hg CLI commands. It is not possible to automatically convert it, the problem isn't the repo using git or hg, the problem is ML build system tries to use hg tools, and expects hg related directories to exist. You must modify the build system if you want to manage ML code using git.

The commits I link to make those changes.

Hi, just put the 2021-Version on my 450D -fine.
I have already my other 600Da (astro) with ML so want to use this as many others as 2nd device in the night (after get rid of th LPT2-Filter).
Well - I mainly use the Intervalometer to avoid the need of an external control.
So what I really miss is the control/entension of the shutter time in bulk mode (to get 60sec or more).

Is there any chance to get this (simple?) feature into the firmware?

KR
Marcel

names_are_hard · « **Reply #119 on:** November 07, 2022, 09:56:02 PM »

Hi,

First, it's not likely as simple as you expect, second, the number of developers is very small. The number of devs who own a 450D is probably 1: Ant123. Either they notice this and decide they want to spend several days (at least) trying to get intervalometer working, or you'll need to learn how to do it yourself.

dl1ekm · « **Reply #120 on:** November 08, 2022, 02:53:21 PM »

No problem - if this is really the case - makes no sence :-) I'll stay with external control. Was just an idea. But anyway - thank you for the work so far!
