I tried several times to get this working (pearl DPF @ Raspberry PI) but all of the howtos are not working/ have errors in the steps and so on.
Thanks a lot!

And what errors did you encounter?

[m_K_o]

I'm also currently stuck with:

Code: Select all

Found AX206 DPF (bootloader)
Error: Failed to claim usb device!
Possibly you have to 'sudo libhid-detach-device 1908:3318'
dpf: cannot open dpf device usb0
Error initializing driver DPF: Exit!

libhid isn't apparently available via apt-get and compiling it by myself is pretty hard with my current knowledge of linux stuff.
I already have latest svn of libhid, but don't know how to continue from here.
Any help would be appreciated.

Got the same error when I ran the test config for lcd4linux too. Whats wrong? Do I need to edit the conf file?

Is frame in bootloader mode - press menu and reset together? You may need to execute hiddetach as well.

No, it was not in bootloader mode.

Im now holding manu and pushed reset, and it is a HID device now, but I still get the same error. How to execute hiddetach?

[m_K_o]

Got the libhid compiled and device detached but still no go.
Now I'm getting this:

Code: Select all

Found AX206 DPF (bootloader)
DPF: framebuffer could not be allocated: malloc() failed
Error initializing driver DPF: Exit!

Now I have absolutely no idea what to do.

[ax206geek]

@m_K_o:
Did you execute the commands as root user?

@Norefall:
The hiddetach is in fw directory. It is a shell script.

Oh.. It works. Thanks!

So this DPF is not hackable?

Mine also wasn't recognized using the python tools. But it worked with the windows tool, once I had the proper INI file and the image for my particular device. I found both in a different forum. Sorry if I cannot be more specific but I am on a business trip.

Yes.

Here's all the info i have about my dpf:

Now I'm wondering if i should be running some hacked firmware on the dpf... and if so, where would i get one?

I don't have the skills to hack this type of frame yet but you can backup the firmware with fulldump.py and upload firmware like m_K_o and I will cross-post it to forum.doozan.com to have superelchi to take a look - or you could do these steps yourself.

I'll try to hack it for you or you could post the firmware to superelchi at forum.doozan.com to have a look.

Try this. You have to unzip the file first as the forum only allows zip extensions.

Now i got the googly eyes and menu, but having hard time getting pi to detect it correctly.

Same thing in both "normal" and bootloader mode.
With progspi i can detect it, but I'd need to enter some flash info (that I'm not sure about) to get it to flash.

[ax206geek]

That's an indication the frame is already hacked so you don't need to flash it anymore. Try lcd4linux or any other compatible program like ax206term or dpfsend.

Is there a manufacturer or link?

@m_K_o:
Try a different cable. Some of the shipped cables that comes with the frame are of bad quality. Is the display and menu working normally?

[Norefall]

Not that I know of. I threw the box and cover it came with. Thanks for helping me ax206geek!:) I will try the proposed fw.

[Norefall]

Is there a manufacturer or link?

I think I found it. When I was trying to flash the fw from superelchi I got this:

Code: Select all

Found AX206 DPF (bootloader)
Manufacturer: Apple
Size : 1 MB
Flash size mismatch, specify -f to force

As you can see, there is a mismatch in size (~28kb vs 1MB), but it says my Manufacturer is Apple.
Shuld I force flash?

[ax206geek]

@Norefall: Yes, with -f

[Norefall]

@Norefall: Yes, with -f

Yey, it's hacked!:) Big thanks to ax206geek and superelchi!

m_K_o:

Same thing with three different cables. Even with the cable that came with it, it detected just fine before the firmware flashing.

[ax206geek]

@m_K_o:
If the USB errors appear in bootloader mode, it is unlikely it is due to the new firmware you flashed since bootloader mode works even with a blank flash. What other USB peripherals is plugged to the r-pi? Have you tried rebooting the pi?

Do you have desktop linux to reflash back to the original firmware with restore.py? doozan forum might have the right flashlib for your device for ProgSPI, see this: http://forum.doozan.com/read.php?9,2435,9541#msg-9541.

[m_K_o]

@ax206geek
Restarting pi fixed the detecting issue.
Also the flashlib you linked contains info for my dpf so I'm also able to flash with my win7 now.
Big thanks for all the help so far.

[ax206geek]

@m_K_o:

That's great. Is the hacked frame working? Do you have a link of where you bought the frame/manufacturer? I'll need to update superelchi with these details to commit the code so others who got the frame can hack it too.

[m_K_o]

@ax206geek

I believe the frame itself is working, but I'm still having some issues.
I'm getting "bulk write: Resource temporarily unavailable" whenever i run lcd4linux.
It prints something on the top half of the screen and then goes back to googly eyes.

Frame is bought from here: ebay.de link
Let me know if you need any other information of the screen.
