On 32 GB cards, the ML does not load. I tried it on two other cards.

You can try this build

I do astrophotography and I need to brighten the view on the display so that I can set the focus on the stars. New versions of ML have this function available. Would you be able to program it into the 450D version? It would help me considerably. If you can do it, I would be willing to pay for that, just name your price.

Which function do you need? Can you explain exactly?

Note: ML is not a commercial project, so I do not need your money...

I've put ML on the card.

Probably ML can't find some files in ML folder on SD card.
Try to format SD card in the camera and reinstall ML.

[Trash]

3. During update blue led is blinking and nothing happend.

Installer for 450D firmware 1.1.0. : https://bitbucket.org/Ant123/magic-lantern-40d/downloads/ML450D110.fir
It works the same as 40D/5DC installer.

From 5D Classic thread:

7.) Launch the firmware update process. If you see any red led, then something went wrong. A solid blue led means that the bootdisk is now enabled. A blinking blue led means the bootdisk is now disabled (if you want to completely uninstall ML). Each time you run the firmware update it just toggles the bootdisk to the opposite of whatever it is currently. The installer FIR will make your CF card bootable for you, no further work required here.
8.) Turn the power switch off and pull your battery to turn the camera off. Just turn the camera on (make sure autoexec.bin and ML directory are on the card!) and you're all set. Press the Trash button to bring up the ML menu.

You only need to run the firmware update to enable the bootflag ONCE. Each time after that will only disable, re-enable, disable, re-enable, etc. the bootflag.

When will all these buffers be supported in QEMU?

But direct font taken from ML doesn't look beautiful...

RBF font looks better:

from 0xBFE00000, size 0x200000  - camera locks up with Err70, no log is saved.

0xBFF00000 memory region contains message buffers shared with MZRM core. So probably io_trace code is not fast enough for transfers caused by memcpy.

Does MMIO trace work in LiveView mode?

On EOS M3 io_trace causes crash in Rec mode.

- emulation is able to reach GuiMainTask (after updating the MPU messages and some trivial GDB patches - not yet committed)
- it gets stuck trying to communicate with Zico/MZRM (as expected)

Have you tried to apply modified EOS M3 patches? (0xFC3F1110, 0xFC3F1114, 0xFC3F1178)

Some progress with Zico core emulation:

But I found these fonts in M3 rom:

16 of them can be opened with FontForge

Also there need to decode images from ROM used to draw icons and some texts in Viewfinder mode.
These are vector graphic objects. They can be found by signature "99 99 0C 00" in DSLR's ROMs too. The next 32bit word is a size of drawing object.
Probably there need to use OpenVG to render it.

If you receive these strings from MMIO hooks, or from breakpoints into certain drawing functions, you will need to store them somewhere in a data structure, until the next display event comes up.

I recieve these strings from eos_handle_digic6: mzrm_send function writes 1 into register 0xD20F0840 to inform Zico core about new message.

I was trying this code, but it doesn't work:

Code Select Expand


DisplaySurface *surface = qemu_console_surface(s->disp.con);
printfxy(surface, (pos_x >> 16), (pos_y >> 16), "%s", MZRM_str);
Do I need to update the display somehow?

Even calling printfxy from eos_update_display doesn't work.

I think it's possible to emulate simple drawing of text strings in case main CPU will send certain messages to MZRM core...
But on EOS M3  the camera controller still does not allow to start it normally and goes to shutdown.

Got Canon menu navigation working on M3:

Any idea how to render these strings on QEMU VGA screen?

There is another solution without additional hardware. But you need to slow down your projector.

SX70HS

Canon released firmware update for EOS M50.

According to this page

AD80334BBCZ
4 CHANNEL, 14 bit , 50MSPS AFETG+PPP

80D sensor has no ADC onboard?

I am interested in the idea of using this camera as a 4K video camera.

slow image sensor * slow processor * slow storage device = bad idea 

if you could PM me you rom files form a download link somewhere  ?
I interesting in decompiling it to do some investigations in the Jpeg routines .

If you don't want to wait you can download and decompile 1000D fw right now.
Or do you need exactly 450D?

I don't have any code.
But AFAIK this program captures MJPEG frames via USB. I posted the resolution and framerate from video file recorded using this program. The average bitrate was ~30-35 Mbit/s. Maybe it's limited by USB.

Is there any other version which I can record video with?

EOS 450D has no video recording function out of the box. It's only theoretically possible to implement Motion JPEG(848x568px, ~22fps) recording without sound, but I abandoned the porting process in 2016 because of problems with the compiller...

I'm not sure what to explain. Any specific question?

You prepared M50_DUMP.FIR for M50 but today you "expect it to be PowerShot, too"
Why?
Sorry. I forgot to look at the date of your post.

Can you explain?

Unsure about M50, but I'd expect it to be PowerShot, too.

Has something changed since that post ?

- Twitter -> sticky post -> video
Should I go on?

Please recommend the exact version of linux you are using(have used) for it.

Make sure you are using proper speed and signal levels.
FYI, diagnostic uart has 1.8v levels on Digic 6 Powershots.
