Hi,

I am trying to control some Canon cameras using gphoto2 (www.gphoto.org) in my openWrt Arduino Yun. To achieve what I need, one of the gphoto2 developers told me I need to run the latest version of gphoto2 which is 2.5.8. Unfortunately I have not found this recent version compiled for openWrt.

I am fairly new to linux in general and openWrt in particular. My questios are:
  • Do you know if anyone has compiled gphoto 2.5.8 ?
  • If not, can someone point me in the direction on how to compile it for openWrt?


Thanks!

@pacific15,
you may not need the latest version, sometimes an earlier version will work. One of our regulars (SonnyYu) is well versed in gphoto. His notes include:

Gphoto2 2.5.2

and

Arduino Yùn and gphoto - Page 2

SonnyYu will be online in a few hours. He will have more information.

I think it is smart move (cross posting). put multiple horses on race track.  You and winner horse are both happy.

jessemonroy650: thanks! Unfortunately I already tried with version 2.5.2 (and 2.5.4) and it does not work.

Most newer Canon point-and-shoot cameras have no native PTP support as the older ones, because Canon removed this functionality to maximize their profits on more expensive cameras. Fortunately the "Canon Hack Development Kit" CHDK project adds PTP functionality to newer cameras, in particular to one of the cameras I own, the Powershot SX130.

The problem is that as CHDK support is very new on gphoto2,  one of the developers of gphoto2 (Marcus Meissner) told me version 2.5.8 was needed to make it work.

Best!

Sonnyyu:

I was aware of the last thread, in fact I posted on it, but I decided to open a new one specifically dedicated to discussing this particular version of gphoto2 (2.5.8 ), as it has special importance to run on most newer Canon cameras (except DSLRs), as I explained previously. The other thread was generally about achieving gphoto2 to run on Yun, regardless of version, which many users had trouble with, a problem which was successfully solved with your help.

Best.

I planed to do same thing, however in different hardware platform.



http://www.tp-link.com/en/products/details/cat-4691_TL-MR3040.html

TL-MR3040/TL-MR11U

AR9331@400MHz   
RAM 32 MiB   
FLASH 4 MiB   
1x 100MBit   
USB 2.0 x1

2000mAh battery, last 4-5 hours per charge.


I made hardware upgrade to

RAM 64 MiB   
FLASH 16 MiB

which is same as Yun.
