dpf-ax: unsupported dpf - requests

@dkrusko
Do you get a white screen when pressing MENU?

@markusbrutus
As I expected. So I will mark xg4241 as "not supported" for the time beeing. :-(
None the less I will put it in svn.

superelchi

@superelchi

No no white screen when menu is pressed screen stays black.

@dkrusko
I am still waiting for my linkdelight. Please keep monitoring this thread. I will post my findings here.

Hi Superelchi,

I found this DPF at a second hand store, they are sold in Australia by Big W / Woolworths.

Zipp Model DP605

The firmware Dpf206.bin from the SDK works except for 180 degree rotated screen.


here@nowhere:~/DPF/dpf-ax/fw$ sudo python ./identify.py /dev/sr1
Detecting & reading dpf flash...
Opening generic SCSI device '/dev/sr1'
Manufacturer: Winbond
Size : 1 MB
Reading 100000 bytes...
Flash written to file 'identify.out/full.bin'.

Looking for firmware.............: Found (buildwin, 128x128 px).
Looking for Openwin..............: Found.
Looking for LcdIniTbl............: None.
Looking for known signatures.....: None.
Looking for known version info...: None.

Sorry, no matching dpf found.


Would be great if you could work your magic on this firmware.

Cheers

@CaptainCheeks

Please try attached fw.

Hi Superelchi,

Your firmware seems to work fine, thanks.

I have maybe found a glitch with this DPF, when I first started messing around with it, USB would sometimes become slow, flashing the Dpf206.bin fw took over an hour, and didn't work. Tried all sorts of replugs/reboots but what worked was desoldering and resoldering the battery wire. After flashing your fw it worked at first, then would have the About screen in the background of the graphs of lcd4linux dpf.conf. Resoldered the power again and it has been fine so far.

Cheers

I will add this model to svn, as soon as version 0.4 is ready.

Your problems look like a defective device to me. Maybe the battery? They are known to be of low quality. If you want to use the dpf as a status display with lcd4linux I would recommend to disconnect the battery. The dpf will be powered by USB and turn on/off with your computer.

@ Papa Oscar

Finally! My LinkDelight dpf has arrived.
Please try attached fw.

OK, now works correctly, I see the glass combined. Superelchi thank you very much for your dedication, the wait worthwhile, would also be willing to contribute to your research,,,,, if possible you had a Paypal account.
best Regards

Okay. So I will set the status of this dpf to "supported".

Thanks. But this is one of my cheaper hobbies. ;-)
Once in a while a new dpf. Not a big deal...

superelchi

superelchi

Thank you, it is working very good now.


Dkrusko

Fine! So I will mark this a "supported" too.

superelchi

@markusbrutus

Here we go: please try attached fw.

Hej superelchi,

some days ago I got my order from LinkDelight which is in the knowntypes list of dpf-ax.
It should be a delightdigi_2_portrait. But as so often, I don't know if they changed their pants... but I'm pretty sure, they changed the firmware. ;-)

I did a full dump of my dpf and attach it to my post.

Maybe you have time to take a look at it? :-)

Thx a lot!

Greetz,
Mr. P

Yeah - new pants. ;-)

Please try attached fw.

superelchi

Hej superelchi,

thank you very much for this prompt implementation.

I flashed my dpf and can now start lcd4linux without errors.

Unfortunately, the screen remains blank (just the backlight is on). There is also no difference, when I change the color settings in the lcd4linux.conf.

You don't know what's wrong, or better yet, what could I do about it? :-)

Thx a lot!

Greetz,
Mr. P

Hmm..

Can't find anything wrong.
Do you see the splash screen on power on?
What happens when you press menu?

superelchi



Edited 1 time(s). Last edit at 03/28/2013 05:23AM by superelchi.

No, I don't get the splash screen.
I also tried to set any custom start screen - same result.

When I press the menu button, nothing happens.
But when I press:

Menu -> 3x Right -> Menu = the display restart (also see it in my /var/log/messages that the USB reinitialize)
or
Menu -> 3x Left -> Menu = the display switch off and after another press on Menu the background light reappear.

Is it possible that there is a setting for brightness and/or contrast which is set too high or too low?

Greetz,
Mr. P

No, even in this case you should see something.
Please try attached fw. I made some small changes.
If this does not work either (what I expect), I have to dig a bit deeper...

Could you try to adjust the brightness setting in lcd4linux and report if the brightness of the display changes?

superelchi

superelchi Wrote:

This fw didn't change very much - still the same problem.

> Could you try to adjust the brightness setting in

Setting brigness to 0 ... black screen.
brightness 1 ... screen ist on.
brightness 7 ... screen ist brighter ... but the difference between 7 and 1 is minimal.

Regards

Very strange.
This fw is - besides init & blit commands - identical to linkdelight_black_portrait. I can see absolutely no reason why it should not work.
Are you sure the fw you posted here is the right one?
Did you re-flash this fw to your dpf? Does it work?

superelchi

Yes ... I'm pretty sure I used the fw from your link :)

And I use "restore.py" to flash the device (I'm using Linux) ... this should work?

BUT ...

Initialy I started flashing the DPF with a different fw ... I didn't work - I didn't have a copy of the original firmware :(

But we did have a "untouched" devices - so - I read out the original fw from that device - and flashed it back to the one I had "manipulated" ... still the device did not work - even with the original FW ...

the question is - the fw we get from you should work - regardless of the condition of the DPF?

Yeah, if restore.py did not throw any errors, everything should be fine.

Do I get you right: the one you try to flash does NOT work with the original fw you postet?

> the question is - the fw we get from you should
> work - regardless of the condition of the DPF?

No. What I do ist extract the lcd-specific parts from the original fw and "inject" them in the custom fw. So if the dpf does NOT work with the original fw it will for sure NOT work with the custom fw.

Did you try to flash the dpf you got the original fw from with the custom one? Does this work?

BTW: have you tried the other two know 240x320 portrait fws (delightdigi_2_portrait and linkdelight_black_portrait)? See attachment.

superelchi

Hi.

I got it working... :)

The first full.bin we (Mr.P) sent you - was the one I read out of one of the original boxes ... I was wondering why I just was 1MB large ... Anyway ... I found another "untouched" DPF - read out the FW again ... and guess what ... this time 2MB :)

Maybe my original setup (other PC, other cable) was broken ... anyway ...

flashing this 2MB FW to my "broken" DPF made it work with the original FW :)

And ... flashing the fixed DPF with fw_linkdelight_black_portrait - WORKS!

Thanx from Mr.P and myself!

Regards

Hej superelchi,

also a big thank you from me. The firmware works great here too.

Just one thing, I don't understand. How could it be possible, that 3 of our 5 ordered dpfs created a crapped dumpfile (I checked the md5sum from two of them and guess... they matched). We created the dumpfiles independently on different computers.

But at least... Everything works fine. :-)

Thx a lot!

Looks like you got two different hardware versions from LinkDelight.
The dumpfiles are not crapped. Looks like these three dpfs have a 1 MB flash chip, the other two 2 MB. Fulldump.py and/or identify.py will detect the size of the flash and generate a 1 MB or 2 MB dump accordingly.

Just to be sure: the new "linkdelight_black_portrait_2" fw works with the dpf you made the posted dump of?

No, it was the 'fw_linkdelight_black_portrait' from your post. But we always have to use the '-f' option for flashing because the flashsize is mismatched.

On Tuesday we will try to flash the other 3 DPFs... I'm very curious if we can use the same fw for all of them. :-)

Hej again,

we flashed the remaining displays this morning and exactly one had the 1MB flash I initially sent to you.
Sounds to me like Murphy. ;-)

So we could flash all DPFs. Four of them with the 'fw_linkdelight_black_portrait' from your post above the last one with the file from this post.

Thanks again from my colleagues and me! :-)

That is good news.
So I will mark linkdelight_black_portrait_2 as working.
