pv2tool for linux
I am starting a pv2tool linux port on the pv2tool sourceforge page. It should be relatively easy to port since Pv2Tool is very similar to Ops and all of the ops for linux code can be borrowed. For instance, one of the most difficult parts of the ops for linux project was implementing the file tree view on the window. Implementing this in pv2tool for linux is as easy as changing the commands sent and parsing the data gotten back differently. Progressbars are another thing already figured out. Anything done mostly with libusb is easy to port. Pretty much the project will consist of copying a button's code from pv2tool and making it suitable for gtk and c. Things with dialog boxes and other graphical bricabrac are a little trickier. (Ie: porting the unlock code could be done in 15 minutes, where porting something with a lot of checkboxes would take hours for someone with a little experience in gtk.) Anyone who wants to help is welcome!

I've put together a very primitive version of pv2tool for linux. It opens, unlocks, and closes the camera. (Ignore the non-functioning update-directory-listing button). The files will be or are in the sourceforge cvs under modulename pv2tool-for-linux. (See sticky on this forum for location of sourceforge page) I need somebody to -*test*-('") the unlocking button if possible because my camera is already permanently unlocked and can't be a good -*test*-('") subject. I believe it should work since the code is essentially bill's with few changes, but I want to be sure. The next part is improving the 'update-directory-listing' button so it works. This will probably be the most difficult part. I'll: - start with the ops-for-linux code and remove references to partitions and a "root" node since cameras have only one partition - put the bootsector reading into a function and replace GetFileInfo with something which access this bootsector information instead - If a bunch of buttons are simple commands to be sent, that'll be easy to implement. (That rhymes!)

things work now! The CVS version allows you to open, unlock, take a pic, and update the file listing (with icons!). The update file listing thing was definitely the hardest thing to implement. It's there now though. Everything else should be bananas.

I looked around the SF page and didn't see any mention of linux. I tried "make"ing around in my unzipped folders, but clearly that isn't the way to do it.

it's only in the cvs repository right now. it's far from complete though, and the functions it does do now probably wouldn't allow you to do much

could you try porting pv2 fetch too?

beef, you could always just sudo and then run the program

Heh, I'll worry about sudo or some other mechanism once get this camera unlocked. Plugged in the camera (no batteries) # lsusb Bus 003 Device 004: ID 04cf:8818 Myson Century, Inc.

What am I doing wrong? Beef.

I don't know if ygfperson has ported the "SDRAM Keyscan" button - is it there on the panel? If not, you'll need to grab a Windows box somewhere to unlock the cam. Either way, you should be able to follow brite_eye's instructions on the legal method (check out the HOWTO section). Note that you *don't* need to hit unlock when you're connecting in bootloader mode; bootloader doesn't have the concept of a locking.

If you want an alternative to SDRAM keyscan - check my now outdated post before BillW made it much easier: forumer.com/viewtopic.php?t=318" target="_blank">http://camerahacks.10.forumer.com/viewtopic.php?t=318

Did ygfperson implement "transfer memory" and the pv2keys.txt mechanism? If not, then he can't follow that post.
