ML 2.3 on exfat on 60D

[kcleung]

I am testing the ability to record >4GB videos, so I need to put ML on exfat-formatted cards.

I tried to unzip all files onto my exfat-formatted card, but it does not work on my 60D.

How can I get ML 2.3 working on exfat-formatted cards?  The 60D has previously worked with other ML cards with fat32

I tried the solution at:

http://photography-on-the.net/forum/showthread.php?t=1232870

but when I boot the camera, go to the menu and select "updated firmware", it says "update file cannot be found, please check the memory card and reload the battery and try again"

So is this special exfat-enabled autoexec.bin only for 600D, and not for other cameras?

You're going to have to add it for 60D. That's just for 600D.

Here I don't mean the >4GB recording support.  I just try to get ML 2.3 working on exfat.

Do you mean ML 2.3 exfat support only exist on 600D?

When all else fails, read the manual

The manual just says run make-bootable.sh (that uses exfat_sum), but the scripts claims that I haven't formatted in exfat format, despite  I followed the instructions to format in exfat and with label of EOS_DIGITAL

To get exfat working on a <=32gb card, format it to exfat in windows. Then make it bootable with eoscard just like any other SD. Those scripts aren't the best.

My computer has Ubuntu 12.04 amd64 installed, with the ML from:

hg clone https://bitbucket.org/hudson/magic-lantern/

on the unified branch.


Then I formatted my Apacer class 10 16GB SDHC card to the exfat format with the label "EOS_DIGITAL"

Then I go to:

magic-lantern/contrib/make-bootable

and I run:

make exfat_sum

to create the executable

Then I followed the instructions in INSTALL.pdf in the ML 2.3 zip file and run

sudo ./make_bootable.sh



However the scripts apparently fails to recognize the partition as exfat

Initially, I formatted the card with OS X 10.8 on my macbook, then I repeated the above procedure by formatting the card with Ubuntu 12.04 amd64, but with no luck


Also in INSTALL.pdf from ML-2.3, it just say prepare the exfat card with make-bootable.sh, however should this be done before, or after unzipping ML-2.3 zip file onto the card?  I am really confused.......

To get exfat working on a <=32gb card, format it to exfat in windows. Then make it bootable with eoscard just like any other SD. Those scripts aren't the best.

Have anyone tried to format the exfat card on OS X 10.8 or ubuntu 12.04 using exfat-utils 0.9.5?

Thanks!  I have just manage to get my 16GB exfat card working on ML 2.3

The procedure I used was:

1. format the card in exfat with Windows 7
2. run EOScard 1.2 with EOS_DEVELOP and BOOTDISK strings checked on the card
3. unzip ML 2.3 onto the card

The card now works.  However on my 60D, the recording still stops at 4GB, although I will talk about this problem on the development thread


By the way, are there ways to get the algorithm used in the EOScard 1.2, so that one can implement an open-source software on Linux that can do this job to make the card ML and CHDK bootable on any exfat card regardless of size?

I need to try this. But I assume that we need to delete the movies and photos opposed to formatting the card in camera.
