Koreader crashes on Pocketbook Color Lux PB801

[ibiza666]

I got my Hands on an old and not so good(for various reasons) color reader for my kid. Pocketbook Color Lux PB801
I was not particularly satisfied with the integrated reading programs, so I tried cool reader, which was amazingly fast but lacked color support und has no device support since 7 yrs.

So I tried koreader v2024.11
But after I copied the application completely to the reader and adjusted the extensions.cfg to open epubs with koreader directly, the application crashed on startup. Here is an excerpt from the crash.log

I think that the model is recognized correctly, but my programming and lua skills are not ready for this^^

The color lux was certainly not the favorite child of the ereader scene, but I would appreciate any support.

[Frenzie]

Try the latest nightly: http://build.koreader.rocks/download...02-10/?C=M&O=D

[ibiza666]

Tried latest nightly, however same error.
But I assumed that this worked in the past. So I tried older Versions of koreader and the first that booted, but had wrong orientation was v2015.11-stable.
The first which kind of worked was v2018.12, but changing some settings freezes the device. power off with long button press needed.
I try to find the point, where the regression was introduced.

[Frenzie]

Can you change line 243 from

self._model_init()

to

self:_model_init()

[ibiza666]

Yeah that fixed the first error. But it segfaults later:

You could see if there's an updated firmware version that helps, and otherwise it should work if you change the device definition to hasColorScreen=no.

I think I am on the latest firmware. However most probably Pocketbook does not serve any new FWs for this old device anymore. I Stand corrected, you can download the fw here: https://download.pocketbook-int.com/...riton_user.zip
However it is an older Version, than I have right now and it won't update.

The latest Koreader which is working "better" than 2018.12 is v2019.03.1. After that Koreader ain't gonna start or create a crash.log.

I'll try hasColorScreen=no, however this is not ideal^^
Edit:
Just tested hasColorScreen=no. It works as expected
(however, crashes when opening the top Menu, with touch. Button works -.-
I think this device is flawed) now it is working...

Koreaders Fileexplorer on the otherhand does use colours nonetheless and works.
How is the Framebuffer handling different between fileexplorer an Reader?

-----
Ok Ok. After changing canHWDither from yes to no color is working again. However I am unable to open the top Menu (with button or touch)

edit 301:
undefined symbol: PartialUpdateHQ gave a hint, and looking through the code I changed it to the following:
/applications/koreader/ffi/framebuffer_pocketbook.lua Line 36-40

if fb.device.hasColorScreen() and hq then
        inkview.PartialUpdateHQ(x, y, w, h)
    else
        inkview.PartialUpdate(x, y, w, h)
    end

quick and dirty to

if fb.device.hasColorScreen() and hq then
        inkview.PartialUpdate(x, y, w, h)
    else
        inkview.PartialUpdate(x, y, w, h)
    end

Now the Menu is working, I'll test it further.

There is inkview.FullUpdateHQ() also. I think this is doing a fullscreen Update e.g. after 6 pageturns. But this is working as expected.

[dmalinovsky]

Yes, inkview.FullUpdateHQ and inkview.PartialUpdateHQ functions are available for newer firmware only, that's why I suggested toggling hasColorScreen to "no". Does it make everything black and white with that flag?

Yes, this option renders Images b&w. The fileexplorer still renders Images of book covers in color.

What did the trick in the end was reverting hasColorScreen back to yes and changing the option canHWDither to no. This allowed coloured images but broke the top menu.
There are still some crashes, but reading and changing document settings is fine.
Should I open a github issue?
