Porting Rockbox to YP-R0 (FAQ in the 1st post)

[kugel]

I'm considering to get an YP-R0 to help the port. Anyone has hints where to get one (cheap) in Germany?

Hi Kugel,

I'm very pleased to read that!

The R0 has been discontinued for about 1 year now so it will be difficult to get a brand-new one.
You can get a second-handed one on ebay for instance: http://www.ebay.de/sch/i.html?_from=...All-Categories There are 2 cheap 16GB R0 for sale (one auction ends in 7 hours). If you don't buy them I might do it so bid quickly :P

If you don't find any and as you're in Berlin, I may lend you one of my 3 R0s for a few months (until April max as then I come back to Paris) is that really can help for the RB port. But I would prefer you to buy one yourself as I really love -almost need- to see my 3 R0 every evening

Great news!

lol for the video, nice to see something like that hahah (indeed the quality needs to be top for such things )

@kugel: great! Because at the moment I have so few time to spend on it
...moreover I'm still quite newbie in C-rockbox. Not that good indeed hehe

@lebellium: it would be great if you can lend him the stuff

Lol, Samsung should make that syscheck screen with trollface on it.

In Russia i guess they are still selling 'cause i bought myself one no more than 2 months ago. Wonder why is Russia always such amount of time behind other world

Alright, I got one from ebay. I should be able to help with the port soon.

BTW: The Rockbox fund is going to help me with buying this device. That's one of its main purposes. We always welcome contributions to the fund, so feel free to make a donation to Rockbox (the donation button is on our front page).

Great great great
Then when you will receive it, I will give you all the information you want...

Very good news!

Congrats to all hackers/developers for successfully porting Rocbox to our beloved R0's. Merci à tous. Grazie mille (esp. Lorenz092, lebellium & slade)
I have been using it for one week, and I am already looking forward to newer versions, especially to a "RB only" loader!!

I have found a few quirks, nothing special. but now I pose a simple question that's been puzzling me.

How to use the colour selector screen??? Apparently, the obvious up/down buttons do not change from R to G to B sliders. So you can just edit the red component of the colour. I don't know if it is a bug or I just am not doing things right.

Thanks again!

This is a bug in apps/keymaps/keymap-r0.c. There are a lot of different keymaps for all the different settings screens.

        case CONTEXT_CUSTOM|CONTEXT_SETTINGS:
        case CONTEXT_SETTINGS_RECTRIGGER:
            return button_context_settings_right_is_inc;

        case CONTEXT_SETTINGS_COLOURCHOOSER:
            return button_context_colorchooser;
        case CONTEXT_SETTINGS_EQ:
            return button_context_eq;

        case CONTEXT_SETTINGS_TIME:
            return button_context_time;

Having something like

        case CONTEXT_CUSTOM|CONTEXT_SETTINGS:
        case CONTEXT_SETTINGS_RECTRIGGER:
            return button_context_settings_right_is_inc;

        case CONTEXT_SETTINGS_COLOURCHOOSER:
        case CONTEXT_SETTINGS_EQ:
        case CONTEXT_SETTINGS_TIME:
            return button_context_somethinggeneral;

might suffice... But the coder here is Lorenz092. What do you think about that?

I can't do any testing with my R0 until I manage to get rid of

/home/olojkine/rockbox/apps/settings_list.c:1903:5: warning: missing initializer
/home/olojkine/rockbox/apps/settings_list.c:1903:5: warning: (near initialization for 'settings[157].<anonymous>')
make: *** [/home/olojkine/rockbox/YP-R0-build/apps/settings_list.o] Erreur 1

. Any idea ?

[Lorenz092]

Sorry for the delay of the answer

For keymappings, yes, I guess I built everything in a messy way. Need to split properly the right parts. A rework is needed indeed.

For the latest SVN, this evening I should have some time to test that. I guess that some definitions are missing, probably also in the keymap file for shortcuts page? Just an idea....

EDIT: this morning kugel has done some great work!
- SDL removed completely
- using now ALSA directly
- libuisimulator removed (simulator stuff)

[lovasoa]

Wonderful! Can we see the patch somewhere?
Does removing SDL audio backend also removes sound glitches?

As kugel is part of the rockbox team, can we expect to see YPR0 becoming an official target soon?

I'm asking the patch right now
For the glitches I'm still not sure. We need testing. For example I don't have any glitch also with the current build but lebellium does. Let's see!

And yes of course it will be an official target, don't worry

maybe you should insert a kind of index on page 1, so everybody can have a quick glance on the progress - and the latest download is also listed.
just my 2 cents - i followed the hole thread so i dont care too much, but it could be quite hard if you just joined
btw superb work! just hit us with any update - no matter how infinitesimal it may be - so it can be tested an you can get the feedback

That or a wiki page.

Did you see Lorenzo how all RB developers have put pressure on you for a few times; I think you have no choice now, edit this f**king wiki page ahaha

[Lorenz092]

Okay okay you convinced me

I'm editing it right now inserting all information I know...

[Predelnik]

I've got a little problem with last.fm scrobbler actually, don't know if it's player dependable though. The problem is that when i stopping playback in second half of the song, and then resuming it, the song is written to log 2 times with "L" mark, so i need to do manual deleting of entries pretty often. Can it be solved in some way and does other players with rockbox have same issue?

Port issues (device specific)-> IF: audio flickering, display color problems, power management issues etc...
Application issues-> something not related to the hardware, logical/algorithm errors....like this last.fm. I'm pretty sure it does the same on all the players

[MrVibrating]

Sorry if this isn't the place to ask, but i'm curious whether the "sound settings" (bass, treble, EQ etc.) will apply to the radio too? Or are these functions specific to file playback, like on the R0 app?
