Good :)
I just updated the wiki, expliciting it works on VX747+.

hello
am new the forum. am interested in help porting rockbox on vx747. i have hardware and knowledge on processors. i have player with me and able to upload bootloader.
has anyone able to upload rockbox yet? the stable release code base is not fully compile the code for Normal mode. on forum i found that someone was able to play audio, but garbage. where is that code base?
thanks
jaining

Hi,
the current focus is on USB and trying to get some storage to work (I still haven't committed the USB drivers, I'll certainly do it today).
I got audio out of the device several times, the first time it was 'recognizable' but after that it was just garbage and I haven't put any energy in it (as it's not a priority).
The codebase is in SVN and in my local tree (but not for long).
There's no point compiling Rockbox (non-bootloader) as there's no storage to put it on (except for the RAM-disk, but that's not really an option).

Thank you for quick reply. I hope to use the code after u comitt to the SVN. please reply when u do.
For storage, i look at wiki page, shows that FLT not known yet. But that is needed only if we want to run both original FW of player as well as rockbox. what if we format the flash with known FS like FAT, and run only rockbox? please tell if i miss something here.
thanks

Yes, that's possible but how would you know which blocks are currently marked as a bad block?
If you would ignore that, you would get in trouble pretty quickly as on every NAND chip there are several bad blocks.
When a NAND chip is shipped, the manufacturer has marked these blocks in a way like they described in the datasheet; but as we currently don't know the FTL we also don't know which blocks are bad.
Also, there will always be a need to run the OF (especially in the beginning, when not all drivers are fully developed/working) so it would be better when we use the original FTL.
If you really want to get some storage working, I would say you should look after microSD.
I did a little bit of groundwork there, but got stuck at some point.
And just 'formatting' the NAND as FAT won't work either, there's really a *need* for a FTL (bad block management, Google for more information).
