Eos 400d ( Rebel XTI )

Hi guys,

Great Project, thank you for doing it.

I would like to use it on my 400d also, but i cannot seem to make it work. A while ago(2-3 years back) there was another 400d hack Project, i dont remember its name or home page, but it was activated very much the same way. I have a autoexec.bin on my card and i have some (fewer) options in my print menu. now i tried to reflash this testfir.fir and according to what i see, it looks like it is applied normally, but when i change my autoexec files to latest from this Project, nothing happens and it starts as if there is no hack, and when i change them back, the old Project gets loaded.

Can you help me? I tried flashing to 1.0.5 and then 1.1.1 back again and reapplying everything to no avail.

Thank you,
Marko

AFAIK, all versions and variants of this hack have always used the same method to "install" themselves into the camera. You should "update" the TESTFIR.FIR file just once, then your camera will be ready to use any hack. The fact that you can still use the old hack proves that your camera is ready, thus no further action is needed in this field.

Now, when a prepared camera starts, it checks the card: if the card is also prepared, the camera will look for the AUTOEXEC.BIN fine. If the camera finds the file, it will execute it; otherwise, the camera will fail to boot. Thus, if you can boot your camera with the card that contains the new version of the hack, it means that the camera does not recognize the card. I would try to format and prepare that card again.

Or perhaps you are trying to use the new version of the hack just like you used the old version; this hack has changed a lot in the last years, and you will need to have a look to the user guide.

Thank you for the hint. I have 2 old cards, one 2GB one 4GB, replacing files on 2GB worked, but not on the 4GB. Old Project worked fine on the 4GB, then i saw that the 2GB was FAT and not FAT32, so i reformatted 4GB to FAT also and used EOScard, then set flags and then it worked fine. I have the latest nightly build btw.

Although the hack manual says FAT32 should work as well...

Thank You again.

Well, it works on both version of the FAT filesystem; but, depending on the method you are using to prepare each card, there are some differences on how to do it.

marko259

I used the same EOSCard app for both FAT and FAT32, was i doing it wrong? There wasn't anything really to do wrong.

Anyway, i was hoping you could explain the ISO in viewfinder feature. I was able to get it working but it works very weirdly. I have the D-pad enabled from the hack. When i view through the viewfinder and half-press the shutter button and then the up button, nothing happens. When i release the shutter button and press the up key the ISO selection is displayed on the big screen. I am able to get it to work when i press the zoom in button or AF point selection button WHEN i look through the viewfinder, after that i half press shutter again and then i am able to change ISO as instructed. BUT after that i am not able to change ISO or white balance or metering mode the old way, i have to press AF point selection again and then press the shutter half way and then i am able to change ISO, AF and metering the old way again. I have to repeat all to change it again in the viewfinder. If it is supposed to work this way then it is very hard to use. Shouldn't it switch the mode automagically when the proximity sensor fires?

You should also know that i have custom function 4 set to 1, AE Lock/AF, if this changes things.

Sorry. I have never used EOSCard.

The ISO in the viewfinder works only while you are looking through the viewfinder and the camera is displaying the shutter speed and aperture on the viewfinder. You just have to look through the viewfinder, take a measurement, and use the LEFT/UP/RIGHT buttons.

marko259

That's the point, i am looking through the viewfinder, and while i am looking through the viewfinder and pressing the ISO(UP) button the big screen turns on instead of dislaying the actual ISO value inside the viewfinder. To be able to change/view ISO through viewfinder you have to do what i described before.

Perhaps i could make a video of this to explain better, as a programmer myself, i imagine how you would like to flag it as "works-for-me" right now 😀

Ok, I think I got it.

First, make sure that you have the "Use D-Pad" option enabled. Then, while looking through the viewfinder, half-press and release the shutter button; now you can use LEFT/UP/RIGHT buttons for the "ISO in viewfinder" feature, as long as the viewfinder remains lit.

If you keep the shutter half-pressed and then use the keypad, then "ISO in viewfinder" does not work (this is a known limitation); but I have also noticed that a wrong shutter speed may be set (this is a new bug I just discovered).

Hope this helps!

Hi there!

There has been little activity around here lately, but the project is still alive; as long as I have this camera (let's hope it does not break), I have the intention of keep working in 400plus.

Thinking about next version, I have decided to release BETA versions as soon as we reach relevant milestones. I think this workflow will make it easier to follow the project, test new features, detect new bugs, ... I released version 20140521-BETA a couple of days ago; you can find it in the upcoming folder.

There are no user-related improvements in this version, but it incorporates a new "cache hack" (thanks mostly to Sergei and OxAF), and I wanted to make sure that everything works properly before adding new features. I have also recovered the overlay code from previous versions; this feature was the cause of many camera lock-ups, so more camera lock-ups are expected.

Google has changed the terms and conditions of the service that they provided to host our project: we can no longer put our downloads there, and thus I had to move everything to my Google Drive account. All links at the project's site have been updated, but if you find any difficulties downloading files, please let me know as soon as possible.

Please, remember that this is a BETA version, and this is an experimental project; if you really want to "use" your camera, it's better that you stick to the latest official release (20130414-05). This version is intended only for those who want to "play" with their cameras.

Edu.

Good job Edu. I'm still following the forum and the commits in the repo.
As you know I do not own the 400D anymore, though most users don't know.
Anyway I'm still available for questions/opinions/advices if you need them !

I will be around 😀

repeater

Great news Edu. The 400D is still my main camera and will be while it continues to go strong. Not sure what other enhancements can be made to the already great 400Plus firmware but I look forward to trying them!

Still using 400p and very happy with it. Especially the prerecorded settings on the dial is a real timesaver.
I have just bought the S110 and installed chdk, and while the features are good and many and I like the small camera, I really miss the ease of use from the 400.

Thanks again for this fine piece of firmware.

Clapor

very interesting project, thanks for development!

I just revitalized my 400d ... but note that using EOScard (unless under Win 7) you must remove all stuff it creates, before dropping the 400plus autoexec and language file, so may be somebody must change the "Preparing each card" section?

anyway, AUTO ISO works, apparently ...
i.e. you set it, point at something bright and it says e.g. 100 ISO, then point to something dark and it says e.g. 1600, you shoot and after that it says always 1600 even if your are pointing at the sun core!
OR
you set it, point at something bright and it says 100 ISO, then point to something dark and it says 1600, you click the ISO button, and after that AUTO ISO is killed

moreover, "Show ISO in Viewfinder" doesn't work at all and "DP for changing ISO" does nothing ...

suggestions to have AUTO ISO working and never going away?

BTW, puzzle captchas are funny

Unfortunately, EOSCard is maintained by someone not related to 400plus, and there is nothing we can do to improve that tool; I will change the documentation, thanks for the suggestion.

Yes, AutoISO is a bit slow to react to sudden changes in the scene; and I am afraid that there is not much we can do about that.

Claporyou set it, point at something bright and it says 100 ISO, then point to something dark and it says 1600, you click the ISO button, and after that AUTO ISO is killed

AutoISO means that 400plus decides the ISO; if you try to set a different ISO, then you no longer want 400plus to set the ISO, so AutoISO is disabled automatically. If you accidentally enter the ISO dialog, just press DP to reactivate AutoISO.

Clapormoreover, "Show ISO in Viewfinder" doesn't work at all and "DP for changing ISO" does nothing ...

"Show ISO in viewfinder" works for me, and it also works for many others, but it is a bit difficult to get used to it. Unless there is something broken in your camera (does the display switches off when you put the camera to your face?), I would suggest rereading the user guide and practising a bit more.

Sorry, but I do not know what "DP for changing ISO" is... I could not find it in the current user guide.

Hey

my name is Andy and i'm a new 400 plus user 😀

I've got 3 questions:

1: Has someone translated the latest version into German? A lot of menus are still in English!
2: user's guide: German translation has a lot of errors ans is based on an old version of the user's guide. How can i help to translate it?
3. were can i find the ISO in viewfinder menu in the German menu?

Hopefully I've chosen the right topic 😉

1: Has someone translated the latest version into German? A lot of menus are still in English!

As soon as I receive an update for a translation, I publish it as a new official release; so, the latest official release always contains the most recent translation for all languages. Unfortunately, translators are scarce, and some translations are outdated.

Popcorn13
2: user's guide: German translation has a lot of errors ans is based on an old version of the user's guide. How can i help to translate it?

Get a Google account and send me the address (private messages are OK); I will give you write aces to the wiki. If you need help about how to format or update the page, just ask.

Popcorn13
3. were can i find the ISO in viewfinder menu in the German menu?

ISO in viewfinder menu? There is a "ISO in viewfinder" feature, that can be enabled withe the "Use D-Pad" option, but there is no specific menu for it; here is the (English) documentation about this: https://code.google.com/p/400plus/wiki/UserGuide#ISO_In_Viewfinder

I'm looking for a 400D user to run a small test:
http://www.magiclantern.fm/forum/index.php?topic=14732.msg144057#msg144057

It's a portable autoexec.bin that prints "hello world" on all recent cameras, and there are some chances to work on 400D as well (but I don't have this camera to test it).

Knatterman

Hi,

just tried the autoexec from the link. Just a black screen ... nothing happening at all 🙁 🙁

Let me know if I can do sth. else.

Regards
Frank

Here's another test, just to make sure I'm calling the right display init routine. You should get the backlight enabled (probably something displayed as well, but that doesn't matter). The binary is only for 400D, and might cause damage if you try it on other cameras.

autoexec.bin

Source code:

    mov r0, #0
    bl 0xffff8cf0
    loop: b loop

Google is closing Google Code (where 400plus has been hosted up to now), so we are in the process of moving to GitHUB; everything seems has already been moved there, so we sill probably close the site at Google Code in a couple of days.

The new URL for the project is https://github.com/400plus/400plus.

eduperez

After almost one year, we finally have a new BETA version available.

This release does not add any new functionality to the previous BETA, but I hope to have fixed all the issues with freezing cameras. If you want to give it a try, just download it from https://github.com/400plus/400plus/releases/tag/20150422-BETA, copy the AUTOEXEC.BIN file to the card, and enjoy!
