Welcome to the Rockbox Technical Forums!
Greetings!I have just made an acount on this forum to let you know of my troubles with rockbox on my v2 fuze and i can try diferent build's on my fuze to help find the bugs on v2.The only build that doesn't give me the "Bad checksum" on my v2 fuze is this http://download.rockbox.org/daily/sansafuzev2/rockbox-sansafuzev2.zipAnd with this build i can browse the contents of the internal memory and the sd card but when i play a song it plays fine but when it should pass to the next song it crashes.Also i have been trying some games and some of them crashes when exiting.Cumps
Look at rbutil/mkamsboot , especially dualboot/dualboot.S, but I advice you don't modify this code because it's very easy to brick your Clip if you do so.
As far as SD writes go the problem to solve now is a FIFO over/underrun error whenever we try to write to the card. We do get data into the FIFO as you can read the MCI_FIFO_COUNT to see how many bytes are there but I have not yet gotten to looking at the MCI_TCBCNT & MCI_TBBCNT registers (card byte count & bus byte count) nor any sd card response values which may help.
I think we have identified the controller (find it in one of my previous posts) which has both the internal and uSD attached to it. Unfortunately all we have are some lunux patches, marketing sheets, and our own exprimenting to "deduce" how we need to use it.

Seems worth a try.
Now, something else I don't get. What exactly is this AS3525v2? (A quick google search brought lots of Rockbox references.) Is it ARM926EJ-S? (Not that I know the difference) Is it a variant of AS3525 hacked by SanDisk or something different? Is there a spec or at least a summary of differences between AS3525 and v2?
just to report this http://download.rockbox.org/daily/sansafuzev2/rockbox-sansafuzev2-20100408.zip build works pretty well on my v2 fuze 4gb when i get home i'll test it on my other v2 fuze to see how it worksbut the playback seems to be working pretty well on this one i haven't tested any of the other stuff
