i had tried but failed.i 'm sure there is something wrong with the RB .maybe ,the VX777's chip in China is different from foreign
Now I think it's not the Rockbox's fault.You should try to download Rockbox builds for VX777,not for VX747.

I'll upload a bootloader for VX777 for you and try again.
BTW:I cannot find the 'svn' tool in the Ctgwin.Where is it?

Looks terrible.So I had reinstalled my Cygwin and I had to set up the build envoirment--not very diffcult but cost me much time.

That's odd, this could indicate that they have different LCD controllers on different versions of the hw board.

I know that the OF does most of it's LCD initialisation in the bootloader, but Rockbox can't rely on that as it uses a different screen (and probably pixel) orientation.

Does the Rockbox bootloader give a correct screen output?

mcuelenaere: 

The Ingenic MIPS CPUs would be really neat to see test_codec results for.  Could you wget this folder:

http://download.rockbox.org/test_files/

add test_codec.c in apps/plugins/SOURCES

and then run it on that whole folder and post the logs?  Sooner or later we'll have to start optimizing for MIPS and it would be great to have a baseline.

I've tried this before, but last time I did test_codec crashed on several of these files and I never (really) looked into it.

I'll retry and see whether this problem has been fixed/disappeard.

Quite good considering most codecs have no MIPS optimized 32 bit x 32 bit = 64 bit multiply.  We could quite easily improve most of them.

FWIW, from the memory error, I'm guessing you have a 16MB target?  Current test codec isn't smart enough to rebuffer is a file doesn't fit in RAM.  Its on my todo list.

So have you tried to disassemble the OF to find out the FTL?

Why the Ondas doesn't appear on the current build section of the main site?

I guess no one bothered to add them.
They are available though.

I think you need to promote the builds to unstable and then ask Bagder or Zagor to update the front page and the builds table.
