Details

You'll need a file in the
root directory called "rover.raw" that's 4 MB and stereo 16-bit raw
PCM. It'll loop that file.

Note also that it's a bootloader build that does all this..

you also need the TI toolchain

Yeah, so this is how I got real sound out of my m:robe for the first time. It's painfully primitive, but at least we know it's possible ;)

This the same patch adjusted to the ZVM and the m:Robe 500.
It doesn't work yet on the ZVM though.
Could a m:Robe 500-owner or Catalin/jdgordon test if this breaks m:Robe 500 compatibility?

Could be, here's a fresh version.

Should apply cleanly to a clean SVN tree.
