gigabeat screen rotation patch

[lights0ut]

Success! I've got myself a screen rotating gigabeat  . Now on to patching, I have to use week old source code though because of the improvements to the gigabeats, any suggestions on the patches I should use, I don't know of any that are special for the gigabeat.
Here's what I'm using so far:
-Scrolling margins                             -random album database
-Album Art                                        - playlist viewer titles
-(BMP resize if/when it gets synced)   - switch playlist/sound settings in WPS context menu  
-one click to insert                             -spider solitaire
-plugin backlight

Sweet!  Congrats on your success.  

Are you talking about which patches to use for one of your famous builds?

I personally am pretty simple.  I only use the Album Art and Scrolling Margins patch.  Now I can include the Rotate patch.  

Mad Cow has a build with a bunch of stuff in it.

Thanks for taking the time out to work on this.  Sincerely!

Sounds good! Maybe you could also add prompt-rtc, which prompts you to set the RTC at startup if it's reset. Maybe pong-multi-pulse a stardict too?

I can't compile a build right now, and maybe for a while as the network card on my compiling computer just decided to die. I'd rather have somebody else make a good build rather than me, I'm getting tired of waiting for all of the patches to be synced at the same time.

[lights0ut]

Mad Cow, I will be trying to include those patches from your build, I took a read of the tracker pages, and they sound pretty cool. A pong demo that thumps along with my techno will be sweet, and I didn't know stardict can get you wikipedia on your player. And yea the RTC thing helps for the gigabeats because we can turn the power off.
Any other patches I should know about? I do search the tracker often but there's ones that I miss.

evilg123, thats great, congrats!

i'd love to add 2 more patches:

New dict plugin: http://www.rockbox.org/tracker/task/6697
MOD player codec: http://www.rockbox.org/tracker/task/5241

both are synced to the current svn.

You need to first define button mappings, which means you need to find the GPIO data for the UP button, the rest seems pretty self-explanatory. I'm trying it out right now.

EDIT: It oads the rotated binary by default, which is really strange. This is the whole loading part of the bootlaoder:

Code: [Select]

    if (BUTTON_UP) {
         printf("Loading Landscape Mode");	
	loadbuffer = (unsigned char*) 0x100;
    buffer_size = (unsigned char*)0x400000 - loadbuffer; 
		
    rc=load_firmware(loadbuffer, "/.rockbox_1/rockbox_1.gigabeat", buffer_size); 
    
	 if (rc == EOK)
    {
        kernel_entry = (void*) loadbuffer;
        rc = kernel_entry();
	}
         
    } else {
		 printf("Loading Portrait Mode"); 
    loadbuffer = (unsigned char*) 0x100;
    buffer_size = (unsigned char*)0x400000 - loadbuffer; 
	 
    rc = load_firmware(loadbuffer, "/.rockbox/rockbox.gigabeat", buffer_size); 
	 
	 
    if (rc == EOK)
    {
        kernel_entry = (void*) loadbuffer;
        rc = kernel_entry();
    }
}
}

Why does does it not work?

[lights0ut]

gcc tells me that the in function whatever 'button_was_held' is uninitialized.
however, I don't know what this means other than something is wrong, but not critical.
To get the exact error, just try to build a bootloader, it makes the .dat but it just loads as usual.

There's no "button_was_held" function in the bootloader. You have to define the UP button manually and use that. That's what I did, but it loads the rotated build no matter what, even after some help on IRC.

EDIT: I modified you code a bit, it loads the normal rockbox fine, but only loads the rotated buld halfway before going back to normal. I'll try to fix it later today.

Never mind, it automatically loads to rotated build no matter what, I had the path wrong.

Cool, glad to hear you are making some progress and getting help on IRC, thanks for your interest in this

Well I'm done for today, this thing is really annoying. I don't know C, so I'm pretty much guessing where everything goes.

[lights0ut]

don't worry, I am about the same knowledge level when it comes to this stuff. I really should learn C now that I'm done school.

[Mad Cow]

From looking at code examples, I see no reason why this doesn't work.

GOT IT!

It was the button recognition code that was at fault, not the loading code. Because of this, it loads landscape mode with a press anywhere on the touchpad. It's a bad hack, but it works for now. This bootloader looks for both ".gigabeat" files in their respective folders ".rockbox" and ".rockbox_1"

Haven't tried it yet, but SWEET!  Thanks for your work!  And again, thanks to MadCow and EvilG for reviving this effort.

*** EDIT ***
Just tried your bootloader:
* patched, and loaded patched build.  
 Â  * I have .rockbox and .rockbox_1 directories.  
 Â  * Made sure I copied the fonts directory over to the .rockbox_1 dir.
* Powered down.
* Turned the battery off and on
* Powered on.
*Hit/held the up "button."

I received some print out of text that I can't really see because it flashes too quickly.  I believe it looks like the info you get when you don't have the bootloader correctly installed or something.  Is there anyway to capture that message?

After error, it loads in portrait mode.  Everything works fine in portrait mode.
