I did put the first patch of Lyre on Rockbox tracker.

Thanks, you answered my question. I was doing the same thing.
I think it's the sd_crc7 function.
Did you log a chart and want to just have a constant check at all times?
You must be trying to add a second card through the spi secondary. I think there is an e-book (free in pdf format) about this in sd/mmc subject.
I thought you were using definitions to use the atmel library?
You may want to make the data from the sd to be global so the other peripherals can use the data. Just be sure to kill the pointers after the other peripherals use the data.

I must do more tests on SD Card but for now, looks the main problem is on audio drivers, there is no audio out nor time of file do not advance because there is no audio data sent to the hardware.
Bagder:
I went through and renamed all the wiki pages about this subproject on rockbox.org to now use names involving the new Lyre name. If you think any turned out wrong, just let us know and we'll adjust!

I am not finding free time for working on the audio... while that, here is the last video, for the first time I got Cabie V2 theme working on playing screen.

This may help for crc16 function. I didn't go though them yet.

SD Card. CRC16 is done and is working.

NEWS
We are in talkings with Matt, from AVRopendous, to produce and sell a hardware for Lyre.
Matt produce his boards on home, a bit DIY. He can solder BGA. He uses just as possible Free Software tools as KiCAD for schematics and board drawings (as we did before on this project).
Matt sells his boards on Ebay, here.
Matt wants to make a cheap hardware, because he needs to sell ;-) and because of that he choosed to use some Phillips LPC ARM9. Hopefully, we will have a new board with LPC ARM9 + color LCD (16 bit colors + 240x ??) + Lion battery chaged by USB + SD Card + wheel and buttons + stereo audio codec for playing and recording.
Target price is no more than 120 euros (?), which I think is good. And later he can design and make a plastic case ;-)
We didn't get good reception from big companies but we got from "small" business individuals like Matt... we should work together, grow together :-)
I believe that actual working state of Lyre, with the last video I did record, was important for "marketing", for prove that we can do it. It was good for convince Matt ;-)

I am being busy on preparing the Lyre patches instead of being able to work on audio :-(
The Lyre code were for the first time commited to Rockbox SVN :-) :-)
