Re: [Announce] modRana: a flexible GPS navigation system
 

All,

I got another question: is it possible to download maps such as those available from http://maps.google.com.hk/ These maps are in the language that I want. In general, I want the street name and etc to be displayed in the local language of the said location(ie. Chinese(simplified or traditional) in China and english for NA and etc)

Thank for your time,
Cheers,

MartinK, thanks for taking my suggestions into account.

Unfortunately the most recent version has many issues. The new submenu structure doesn't work, often showing empty menus on repeated touch-throughs.

And modRana is more-frequently locking my phone's input entirely. Keyboard, touchscreen, lock, and power buttons fail. Curiously, other running tasks (like mediaplayer + FM Carkit) were unaffected and continued to run until battery reseat.

I'm on the latest CSSU, and using sqlite tiles.

This was mentioned a few posts back. There is a stopgap fix for this here.

what happend to modrana after laste update?it has empty submenus and no gps????!!!!!

Re: [Announce] modRana: a flexible GPS navigation system
 

I'll look what can be done :) BTW, I'm thinking about changing the way map layers are selected, the current click-through method has become a bit tiring for so many layers :) I'm also thinking about a in-GUI layer editor (you can already edit layer settings/add new layers in /opt/modrana/map_config.conf).

Yep, really looks like that infamous SGX-freezing issue again - its really shame the drivers are closed, so no one can take a closer look on this issue... Thinks might be moving in the right direction, if slowly.

I still can't see a reliable pattern causing this, which would enable some workaround. I thought active GPS (liblocation) might be causing this, then someone reported he got a freeze while downloading tiles even with GPS off.
Someone reported on the related Maemo bug, that redrawing on the background might be causing this, so modRana now does not redraw on the background (which sure was bad anyways), but I don't think I got some feedback for this already.
So, did any of you manage to get the freeze with blanked & modRana running ? :)

I haven't been able to reproduce this yet, can you give me some more information ?

• which submenus are empty ? all of them (route,search,etc.) or just the new ones in options ?
• which sequence of buttons you need to push to get to an empty submenu ?
• no GPS = modRana is not activating the GPS and thus not tracking your position on the map ?

Also an xterm log would be really helpful :)

How to get modRana terminal output log:
Open xterm, type "modrana" try trigger the broken behavior (eq. enter the empty submenu) then close modRana and copy-paste the output here (or to pastebin, etc.). Thanks :)

Re: [Announce] modRana: a flexible GPS navigation system
 

Regarding the submenus, it appears that when you scroll down in the new Options submenus, it saves the position of the menu when you go to a different submenu.

I.E. when one submenu has 6 items and you downarrow-tap to item #5, the submenu stays at item #5. This means when you access a different submenu with only one item, you get the appearance of an empty submenu. Tapping the uparrow-button one or more times reveals the single menu item.

Thanks to everyone for the SGX driver issue notice. I'm confident the issue is not related to GPS, because I did not use the GPS during my trip. However, I can confirm that the freezes began happening far more frequently around 0.22-2 or -3.

Something is happening that the graphics driver doesn't like, and as a result input gets frozen. Curiously, other running tasks like audio seem unaffected.

I'll try and record stdout next time I use modRana.

I can confirm that this is the issue... Not a big one, however, since tapping the up arrow brings the menus back in sight.

Re: [Announce] modRana: a flexible GPS navigation system
 

Understadn, the SGX driver is the graphics driver, not the GPS driver. It seems that the graphics driver locks up more often when GPS is on, but that's not the only reason it locks up. Other things that can cause it are lots of re-draws happening and/or when the system is in a sparse resource mode. (eg heavy ram and/or cpu use.) It's also been shown that GSM activity can trigger it in some cases.

That's the reason other things seem to run ok, because they are. The only thing NOT running is the graphics driver, making the display useless. My script actually uses espeak to warn that the driver has gone bonkers and that it's going to reboot your device (just in case you're talking on the phone or some such...)

Re: [Announce] modRana: a flexible GPS navigation system
 

Yes I understand it's the video device. :) Apologies for not ordering my thoughts better in my last post. With luck there will be an open SGX driver someday. And a non-2.6.28 kernel! And... sigh.

Incidentally my device was in offline mode during these tests, to conserve battery life and avoid roaming charges. So my crashes couldn't have involved either GSM or GPS use.

If the problem continues, I will likely try your reboot script/driver. It appears to be a useful workaround, but I hate that such a workaround is necessary on N900 when other Linux systems are so robust!

Re: [Announce] modRana: a flexible GPS navigation system
 

I totally agree. For what it's worth, in the bug link the Nokia rep handling the bug points out the opesource portion of the driver in the git repository at Nokia. Apparently the kernel module is opensource, but loads in a binary blob that runs as firmware on the device. So it may be possible to at least "fix" this in the open part if someone can figure out what's going on.

From what I've read at the TI site, this "bug" apparently was fixed upstream by TI, but Nokia doesn't have the manpower (or is not willing to pay for the update maybe?) to fix it in the N900. Maybe that's something someone can tackle in the new community SSU?
