Not easily. There's a thread in the development forum where I gave some tips on running gdb on the devices. Running gdb remotely is a pain, though. And running it locally doesn't seem possible since none of the terminals seem to be able to support it. However, I've found that you can set up a file of input commands to gdb to run the program and then print out the stack frame where the crash took place, and redirect standard input for gdb to that file. In this case, though, I'm not sure which process you should run the debugger on. The event forwarder? Some lua interpreter? Who knows.

Could some one install this test build on their PocketBook devices? It will log detailed information on the framebuffer configuration of the device from which developers could find a way to solve the display problem on some PocketBook devices.
How-to-test: Just download the unzip the zip package from the above linked page and copy the extracted "applications" directory to your PocketBook devices. Then launch Koreader in the applications menu. And a "koreader.log" file will be generated in the "applications/koreader" directory on your device. It will be very helpful to post the first few lines of that file to this thread. Sample info you may need to post: Code:
PocketBook framebuffer info framebuffer finfo pitc 1200 framebuffer finfo size 1921024 framebuffer finfo pann 1 1 framebuffer vinfo xres 1200 1200 framebuffer vinfo yres 1600 1600 framebuffer vinfo offs 0 0 |

Now we need the above framebuffer info on PocketBook Mini(515) to verify my hypothesis that on PocketBook the actual framebuffer pitch may need 16-bytes padding but not revealed in the fixed framebuffer info. That's to say, pitch size 758 from finfo is not reliable and should always be modified to 768, like PB626. And pitch size 600 should be modified to 608, like PB515(? needs verification). And pitch size 768 on PB623 and pitch size 1200 on PB840 does not need to be modified.

Yes, on the whole the screen looks normal. But in the menus there are smal 'gaps' in some letters. And the contrast in the text is very poor, even though I select darker contrast. And I see the white lines as reported in post #54.

Thanks for everyone here. The framebuffer issue on PocketBook devices should be solved on the next koreader nightly release.

Great job, chrox!
(That's the first thing I should have mentioned yesterday. My only excuse is that it was past midnight for me.) |

Some question:
- Does koreader use A2 refresh mode? I am asking about this because builtin apps have faster and better scrolling. In builtin apps when scrolling page is displayed in black and white (high contrast, no grays), and scrolling is fast. In koreader grays are still displayed when scrolling and it is slower. - Is there any way to go back from filebrowser to already opened document without selecting any file? ![]() |
