Reverse Engineering / Re: MFA on 60D - reversing calibration
« on: September 09, 2019, 03:10:37 PM »
Hello All. My camera come back from authorized service almost 2 with statement there was no issue found (however i got later on information that service noticed AF speed issue but they dont know how to fix it for now). I am not sure if they performed MFA calibration or not. There are few sections in MPU eeprom which has changed after service but it is beyond my knowledge to assume AF calibration data location. Easier and methodological approch may be calibration setup at the table and dump after each action. But SPT software is expensive for this.

I ran linux strings against firmware dump and noticed there are Microdajustment menu entries texts present in firmware. Also there are some other hidden menus and special factory PTP mode.

Code: [Select]
[root]# strings fw/ROM1.BIN | grep -i -e "All by same" -e "Adjust by lens"
1:Adjust all by same amount
2:Adjust by lens
[root]#
[root]# strings fw/ROM1.BIN | grep -i -e "Menu" -e "Factory" | grep "\*\*\*\*\*\*\*"
********** Details Analysis Menu Ver 0.03 **********
************ COMMAND MENU Ver 0.02 ************
********** FACTORY ADJUSTMENT MENU VER 0.01 **********
************ FROMUTILITY MENU Ver 0.09 ************
[root]# strings fw/ROM1.BIN | grep -i -e "FactoryConnect"
FactoryConnect\PTPtoFAPI\PTPtoFAPI.c
Canon EOS FactoryConnect
FactoryConnect\TransparentMemory\TransparentMemory.c
[root@]#


All that brought me to post https://www.magiclantern.fm/forum/index.php?topic=20507.msg217522#msg217522 which confirm factory menu is present. So now question is if AF adjustment could be performed from this factory menu or via Microadjustment menu executed by particular function call.

To be honest with you, I dont know how exactly it works. But from discussion I had with seller after they contacted service on my demand, it seems that calibration will be done via some propietary software in service. Thats where my thoughts came from. That's why i though calibration for particular lens is stored in body itself, but it is not accessible to normal user. I am sorry if I am wrong. I am not requesting microadjustment to be implemented. I just offered my situation to capture some valuable(if any) data.  :)

Reverse Engineering / MFA on 60D - reversing calibration
« on: February 23, 2019, 11:19:52 AM »
Hello guys,

I am owner of 60D body and I bought new lens. As this lens is not working properly on my body (due to FF/BF per Canon service), I am about to send with body it to service for calibration. As 60D do not have MFA available, I would like to help in this regard and willing to dump body before and after MFA calibration for mentioned lens. Let me know if this may be helpful for development of MFA feature for bodies without this feature. If this is the case, I will need guide to what need to be captured before calibration.

@Moderators: I think this could be tracked in separate topic but merge it with other topics if it is duplicate.
