Well Done.

There is no mixer.

It is on the to do list, but no serious work as been done.

These are the current flash partitions.
 
Linux Start
Device Address Size Usage

/dev/flash0 0x00000000 0x000004000 Boot loader
/dev/flash1 0x00004000 0x000008000 Kernel
/dev/flash2 0x0000C000 0x000004000 Params
/dev/flash3 0x00010000 0x000030000 Initial Ramdisk
/dev/flash4 0x00040000 0x000040000 Cramfs
/dev/flash5 0x00080000 0x000080000 Cramfs-user

Later today with init-ramdisk-2-39, cramfs-2-39, cramfs-usr-2-39 they will
be:

Linux Start
Device Address Size Usage

/dev/flash0 0x00000000 0x000004000 Boot loader
/dev/flash1 0x00004000 0x000008000 Kernel
/dev/flash2 0x0000C000 0x000004000 Params
/dev/flash3 0x00010000 0x000020000 Initial Ramdisk
/dev/flash4 0x00030000 0x000040000 Cramfs
/dev/flash5 0x00070000 0x000080000 Cramfs
/dev/flash6 0x000E0000 0x000010000 JFFS

The JFFS partition should give you a little bit of playing room. Once
compression is working under JFFS, then cramfs will go away. If you need
more space, you can store things in the /home or /root directory of the
ramdisk, but if you let the battery run out, then you will have to
re-download your files.

It should be compiled into the kernel. Please look for the device ttyS2 in
boot messages.

I hope this helps. Have lots of fun.
