Won't beat Rockbox !

does metronome plugin work on d2? mine's not...

[3amsleep]

I made a little patch that enables the user to change the tracks while on hold mode by pressing the minus or plus buttons.

Personally I think this feature comes really handy when you're on the street/bus/metro, since you don't have to get the D2 out of your pocket, thus keeping it safe =).

You can get it here http://www.rockbox.org/tracker/task/9875

Also I used Francesco Rigoni button-touchscreen patch and added a way to switch between the 2 touchscreen modes so anyone can test/use them.

D2 starts in the common "button" touchscreen mode, to get into "pinpoint" touchscreen mode press the MINUS and MENU buttons together, to get back to "button" touchscreen mode press PLUS and MENU buttons together.

Hi! This patch works very well, just 2 things:

I can't quit the "lamp" application (maybe there are others which can't get closed).
And the calibrations does not work very well on the right border, i will take a photo tomorrow.

good work!

I Repeat: In touch_to_pixels try to modify "x = val_x / 3.5;" -> to -> "x = val_x / 3.1;"

I'm sorry i will soon commit a patch with this fix included.

EDIT: Done,

http://www.rockbox.org/tracker/task/9590?getfile=18525

this patch is based upon 3amsleep altTouchscreenMode patch, so you only have to apply this one.
However the only change is x = val_x / 3.5; which has become x = val_x / 3.1, you can also do it by hand

explain to ordinary user: how to add this feature? when i try to download a patch i see a bunch of codes

[Llorean]

It's not for ordinary users. Patches are code, to be patched into the source code and then compiled.

@outlawman

like llorean said, "Patches are code, to be patched into the source code and then compiled.", if you wish i can compile a build with this patch for you to test.

@shotofadds

i been reading the code on the arm/tcc780x and it seems that the SD code is getting somewhere, do you think we can expect to be using our sd cards soon?

also, how is that nand driver going, any news so far?.


PS: im trying to understand the rockbox code, its going ok so far, but i think it's going to take some time before i can make any serious colaborations.

Hi, I'm not working on that, ask shotofadds 

@shoto

Can I help you somehow with that nand driver?

[buk]

I'm starting getting into Rockbox code too.
I'm working on getting the "logf over usb" working, it's almost done (juste need minor changes in trunk) but I have issues with USB connection.
Sometimes Rockbox doesn't detect that usb cable has been plugged in. If I set the cpu frequency to 192MHz, the usb initialisation is OK but I have communication issues. The most surpising thing is that it works for days and suddently problems appears.
Does anyone experience this kind of behaviour ? (USB works fine with original firmware).

@shotofadds : if you need some help on the nand driver that do not need advenced skills, I'm ready to help too.

@FranzD2

lol, I just realised I confused you two.

@buk

In my experience with electronics (way more than with coding) I learnt that those "come and go" problems are (really) often caused by wireless interference and heat, they cause the oscillators to vary, thus changing the FCPU;  I would try to get the code to consider such oscillations with a nice calibration function.

my D2(2G) firmware version 2.59
download patch from
ftp://andiators.homeip.net/D2%20rockbox/2009.01.21%20rev19825/d2N_patched2.59.bin

follow the instruction from
ftp://andiators.homeip.net/D2%20rockbox/2009.01.21%20rev19825/How%20to%20install.txt

but it seems not work for me
The screen shows:

*PANIC*
Unknown NAND: 0xEC 0xD5 0x14 0xB6 0x74

And I try to use tcctool to patch
But get the same result

Any idea?

@store88

2.59 is new ground for rockbox, so if you want to test rockbox on your d2, revert to 2.57 or 3.57 and install rockbox.

anyway, what D2 model do you own? (2gb/4gb/8gb/16gb...)

PS: if you had a SD card on, get it out and try anyways.

I have metioned my D2 model is 2G
and follow the instruction I had get my SD out
I will try again on 2.59 firmware
Thx

I recompiled the source, and rebuilt the patch
as a result, it cannot work on 2.59 firmware(2gb D2)
maybe I need to roll back 2.57
'cause I don't know How to make rockbox work with 2.59

Hi!
What's the exact command you used for patching the firmware?

./mktcctool /path/to/D2_2.59/1/D2N.bin /path/to/bootloader.bin /path/to/patched/D2N.bin

should output a correct patched Firmware.

I use Rockbox on a 8GB D2 with 3.59, i don't think there is too much difference to 2.59.
