CF Card Over Clocking on D4 Cams (5D2,50D & maybe7D)

[reddeercity]

Ok we are back at it again , working on over clocking D4 CF Card Bus speed.
Actually i trying to reproduce a old experiment a1ex did on the 5d2 years ago where he over clocked the
CF Card bus speed where he had success but never gave any number on speed .
I'm using the old (ml core) as his code was written in that , the branch is hdparm
I did try to merge it to the new core but it has too many error for me to fix .
So i had to re-install a old ml clone of ubuntu VM with the old tool chain so i just got it running ,
I can compile now but i keep getting a "fatal error" on the cf_acc.mo (module)

hdparm//identify.c:7:25: fatal error: linux/types.h
The problem is there no "Linux/type.h" in the source code at all !
even in the the new core code . Tried to to edited it out but just made things worse .
 Can anybody shed any light on this ?
Here is the source code for the module cf_acc.zip

[theBilalFakhouri]

I think cf_acc.mo module is only for getting CF card Info, or for benchmarks, can't see an overlocking part in source code, here are some replies regarding CF overclocking from SD UHS-I thread:

It's looking for a system header.  Probably should be at /usr/include/linux/types.h.  Do you have linux-libc-dev installed?

[reddeercity]

Do you have linux-libc-dev installed?

no sure , did a find file and i guess i do 

But dose it need to be in the path with the ARM toolchain ?

@theBilalFakhouri look at the code closer under hdparm .

[names_are_hard]

Search using your package manager.  This differs per distro.  If you're using an apt based distro, you can do this:

Code: [Select]

apt search linux-libc-dev|grep linux-libc-dev|grep installed

apt search linux-libc-dev|grep linux-libc-dev|grep installed

Ok got this , I should also mention that I'm using "Ubuntu Mate Desktop Environment 1.8.1" from 2014 i think

Code: [Select]

ml@ml-pc:~$ apt search linux-libc-dev|grep linux-libc-dev|grep installed

WARNING: apt does not have a stable CLI interface yet. Use with caution in scripts.

linux-libc-dev/trusty-updates,trusty-security,now 3.13.0-40.69 amd64 [installed,automatic]
ml@ml-pc:~$ I notice it says "amd64" I'm on 64bit Intel laptop (i5 Dell M430 2.27GHz) does this matter , or is this just
a default file for 64bit systems .

[names_are_hard]

Okay, so you have at least one version installed.  But it's not the one the compiler is looking for.  Could be 32 vs 64 bit, could be amd64 host vs ARM target.  You could use strace to determine where it's searching, which might give you some clues.  It will produce a lot of output, redirect it to file or filter it.

..... You could use strace to determine where it's searching, which might give you some clues.  .....

Ok , i'm not good on linux command line stuff (i'm a windows user)
So i did a little search , and found this https://en.wikipedia.org/wiki/Strace
so i got an idea what it is , but the syntax is a little hard to get my head around .
would this be right ? if i'm in the 5d2 platform  compiling ml ?

Code: [Select]

ml@ml-pc:~$ strace make zipwould this out put a log file or something like that ?

[reddeercity]

Ok run "strace" on make "cf_acc.mo" like this

Code: [Select]

ml@ml-pc:~/CF_Card-Over-Clocking_magic-lantern/modules/cf_acc$ strace make zipIt didn't compile but give a print out what was going on , the only this i could understand was

Code: [Select]

access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or directory)
the "= -1 ENOENT (No such file or directory)" comes up a lot
here the output

ml@ml-pc:~/CF_Card-Over-Clocking_magic-lantern/modules/cf_acc$Here it says it's open up the linux stuff but in the the ml compile file it says it's can't find "linux/types.h"

Code: [Select]

open("/lib/x86_64-linux-gnu/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
this is starting to drive my crazy 

Edit:found out what "ENOENT" is from https://stackoverflow.com/questions/19902828/why-does-enoent-mean-no-such-file-or-directory

It's an abbreviation of Error NO ENTry (or Error NO ENTity)

so back to linux/types.h not being where it should be .

[names_are_hard]

It's normal for strace to show lots of ENOENT during a build, that in itself is not a problem.  The idea is to show where it's looking when it doesn't find them, to get a clue on how your system is configured.  Then we can try to find out what way it's badly configured.

The most interesting part is not strace itself, but this:

Code: [Select]

ml@ml-pc:~/CF_Card-Over-Clocking_magic-lantern/modules/cf_acc$ strace make zip

You shouldn't use "make zip" inside a module directory.  You want to run just "make".

My mistake , it's been a year since I have done any compiling on ml .
but i may have found a clue where the Linux issue is
Here the contents of the Makefile in the cf_acc module

Code: [Select]

# define the module name - make sure name is max 8 characters
MODULE_NAME=cf_acc
MODULE_OBJS=cf_acc.o hdparm/identify.o hdparm/hdparm-routines.o hdparm-ml-shim.o

# include modules environment
include ../Makefile.modules

LINUX_PATH=$(HOME)/src/linux-3.19

CFLAGS += -Ihdparm
CFLAGS += -Idietlibc/include
CFLAGS += -I$(LINUX_PATH)/arch/arm/include/uapi
CFLAGS += -I$(LINUX_PATH)/arch/arm/include
CFLAGS += -I$(LINUX_PATH)/include/uapi
CFLAGS += -I$(LINUX_PATH)/include

# fixme: properly handle generic-y from Linux makefiles
# (hack: copy and rename folders around manually)
CFLAGS += -I$(LINUX_PATH)/generic

test: FORCE
gcc hdparm-test.c hdparm-ml-shim.c hdparm/identify.c hdparm/hdparm-routines.c -Ihdparm -o hdparm-test
./hdparm-test
this is the path to the linux stuff

Code: [Select]

LINUX_PATH=$(HOME)/src/linux-3.1so I assume this is the path to Linux source ml is looking for ?
Is this a path at's in Ubuntu ?

[names_are_hard]

That Makefile is very different to mine.  What repo & branch are you using?

Old core (old 1st gen .raw video before .mlv or mlv_lite) , here the complete source code , 
I downloaded it before ml was deleted CF_Card-Over-Clocking_magic-lantern.zip
here the old link before bitbucket deleted it  https://bitbucket.org/hudson/magic-lantern/branch/hdparm
from a post of a1ex https://www.magiclantern.fm/forum/index.php?topic=19336.msg207053#msg207053

Edit: I extracted the chance set from them the failed build (only cf_acc.mo fail to build) autoexec.bin

Code: [Select]

Changeset: 1af20c52fbe4+ (hdparm)

[names_are_hard]

Okay, hdparm branch, that's on heptapod too.  Yes, the hardcoded 3.19 is likely breaking your build, it points to a location in /home.  That's very hackish.  It suggests whoever was working on this had linux source directly there (and that this code is not at all ready for release).

The clean solution is probably to work out why there's a dependency on types.h and remove it.  Likely not too hard.
