I meant that my canon m50 does not recognize the magic lantern firmware and it won't do a firmware update. I already put in the autoexec.bin file but the camera says "memory card containing firmware is required to update"

the basic is out in JUST THE START not full magic lantern.
It is not only the basic ml april fools you need.
If you look in the forums you will see post with the files you need.

you will need fir files
just the find function on the forum : BOOT_M50.FIR

Personaly i get the awnsers you get from others.
But the forum is for helping others?
I send you in the right direction but do know that ML is not in it full form.

i was also in the dark for the how to, but i invested time and surfed and searched the forum and found my awnsers. TY DFORT for the pointers (Again a hint for searching Matt222Yt)

Also please do not ask ET for full version. just my to cents. alex needs the break

G - 15500 safe limit for my camera
B - 16383

M50 bit depth

Single - 14-bit
Continuous Low - 12-bit?
Continuous High - 12-bit?

Histograms (single, continuous low, continuous high) :


If you want to use 14-bit exposure bracketing, you need to quickly press the shutter button, continuous modes are not 14-bit.

These histograms show dark frames (lens cap photography).
Look at the histogram and you'll see the missing bits. It looks like 12-bit converted to 14-bit.

M50 bit depth

Single - 14-bit
Continuous Low - 12-bit?
Continuous High - 12-bit?

The manual says that the data for continuous recordings are converted into 12 bits...

Do you have a link to said manual? It's embarrasing but all I can find online is a manual resembling a pre-school children book.

Only the German version ‘EOS_M50_Help_Guide_DE.pdf’
https://www.canon.de/support/consumer_products/products/cameras/digital_slr/eos-m50.html?type=manuals&manualid=tcm:83-1667469
Page 88 or search about 12 bit.

The M5 also has 12 bit  in continuous mode...

Thanks! Found english "help-guide" here: http://gdlp01.c-wss.com/gds/2/0300030642/02/EOS_M50_Help_Guide_EN.pdf and the information about continuous shooting bit-depth on page 88, too.

M50 - rolling shutter measurements - https://www.magiclantern.fm/forum/index.php?topic=23040.msg208479#msg208479

It looks like we have 3 readout modes :
Code: [Select]
timer A = 534, timer B = 4061 @ E19EBAC8
timer A = 1064, timer B = 4061 @ E19EBB20
timer A = 772 timer B = 4061 @ E19EBB78

Code: [Select]
[SHTC] ShutterType(1) ReadOutMode(1) ReleaseType(1) // Manual mode, mechanical shutter
[SHTC] ShutterType(3) ReadOutMode(0) ReleaseType(1) // Silent mode, electronic shutter
[SHTC] ShutterType(1) ReadOutMode(0) ReleaseType(2) // Manual mode, mechanical shutter, AEB continuous

ShutterType(1 - mechanical, 2 - ???, 3 - electronic rolling shutter) // 2- electronic global reset?
ReadOutMode(0 - 12 bit, 1 - 14 bit, 2 - ???)
ReleaseType(1 - ???, 2 - ???)

The manual says that the data for continuous recordings are converted into 12 bits...
I didn't know about it.  :o

Any tutorial how to remove that kind of banding? Or just dark frame substraction?

Didn't the latest firmware for EOS R solve that?

I don't know if I should publish this script, maybe I should sell it to Canon?

Is that EOS R with the latest firmware 1.2.0? I saw samples of before/after with big difference. But yes, your script is impressive.

My first post, I am the owner of an M50.  I eagerly await ML for it.  I am trying to read as many posts as possible.

Am I right to say ML for m50 is still experimental?  I will follow these posts for updates and advice.

Cheers

There is no ML for M50 and don't hold your breath.

Well there is this fishy build -- which requires setting the camera boot flag:

BOOT_M50.FIR (confirmed by 71m363nd3r; works on any Canon firmware version)

This will modify your camera.

Right now I'd really like to unset the camera boot flag because when inserting a card that has ML for another camera on it the M50 just goes into a coma. I'd ask for a FIR file but last time I asked for something--well, I won't ask.

Thanks Greg, that was easy.

Anyone else who wants to do this make sure you also set CONFIG_BOOT_BOOTFLAG=y

"when inserting a card that has ML for another camera on it the M50 just goes into a coma"

           Should work if You simply "Hide" ML in a "HidingPlace" Folder/Directoy ~

I am new to all this ML thing, But really want to test out this ML. So today I tested the fishy build on my M50.
The procedure was simple for me, just placed the boot m50.fir into the memory card and updated my firmware from canon menu. After that, I placed the entire fish build into my sd card and by using EOScard made my sd card bootable. Then just booted my camera. And I saw the log getting captured over my display.


And to enter the magic lantern settings, I need to press the delete button, but it didn't take to the ML settings during those presses as much as I need. Then I found that I need to be in video mode to get into ML settings. On video mode, Every press of delete button took me to ML menu.

Also, there is no extra function available on this Fishy build. the modules available are benchmark and self-test modules. Also, the video module in ML menu causes to freeze the camera and the only available option is to remove the battery.

Note guys, I don't know any technical stuff that much right now cause it's my first experience of flashing a custom ROM on Camera. So if any of you guys are free, feel free to let me know about all the technical stuff or at least what I did by flashing that boot m50.fir and how it's going to affect the future of my m50.
