The modified bootloader I used fails to write anything, so I guess the SD interface is different or at another location.

So we need to find the location of the SD interface? Which would be a good place to look; the bootloader.rom or the firmware.mi4?

It has to be in both, but the bootloader is a much smaller file.

My original post seems to have been deleted, so I'll keep it short and sweet. I have a busted View (Screen cracked). All the boards work fine, I will gladly mail it out to whoever needs a backup in case of a bricked View
obo:
For my GSoC work I've been looking at both the bootloader and the main firmware (I've been using version 01.01.06a, available at http://daniel.haxx.se/sansa/view.html). I'm finding a lot of references to registers which match those for the PP502x series, specifically:
Mailboxes (MBX_BASE)
Interrupts (CPU_INT_ & CPU_HI_INT_)
Timers (TIMER1_ & USEC_TIMER)
Processor Control (CPU_CTL)
Cache Control (CACHE_CTL)
GPIOs (up to at least GPIOI)
What I am not finding are any references to the registers for MMC/SD or either of the two LCD base/bridges, which has me a little worried that these might be completely different on this target.
Any advice, guidance or even confirmation of what I've found so far would be greatly appreciated!

Well, about the SD Interface I don't know, but since the LCD is a different size and resolution, I would expect it to be different.
