On a two-plane part an FTL page spans the same page of two blocks, one in each plane, and flash_program() programmed them one after the other: two program busy times (tPROG) per page. The original firmware's FlashProgEnhanced() programs both with one two-plane program - 80h, the first page, 11h, a wait of tDBSY, 81h, the second page, 10h - so the planes share one tPROG. Do the same where the runs of a write cover the same page of both planes, on parts that take 81h for the second page. The original firmware sends 80h there on Toshiba and Micron parts, which address the planes differently too; those still program a page at a time. enum vendor_t moves to nand-target.h for the check. Over USB mass storage on a Samsung YP-CP3 the NAND wrote at 2.22 MB/s, against 4.35 MB/s in the original firmware; now 2.86 MB/s, every read verified.

Build Your Own Rockbox
1. Clone 'rockbox' from git (or extract a downloaded archive).
$ git clone git://git.rockbox.org/rockbox
or
$ tar xJf rockbox.tar.xz
2. Create a build directory, preferably in the same directory as the firmware/
and apps/ directories. This is where all generated files will be written.
$ cd rockbox
$ mkdir build
$ cd build
3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
a particular version depending on what player you are compiling for. These
can be generated using the rockboxdev.sh script in the /tools/ folder of the
source.
$ which arm-elf-eabi-gcc
$ which perl
4. In your build directory, run the 'tools/configure' script and enter what
target you want to build for and if you want a debug version or not (and a
few more questions). It'll prompt you. The debug version is for making a
gdb version out of it. It is only useful if you run gdb towards your target
Archos.
$ ../tools/configure
5. *ploink*. Now you have got a Makefile generated for you.
6. Run 'make' and soon the necessary pieces from the firmware and the apps
directories have been compiled, linked and scrambled for you.
$ make
$ make zip
7. unzip the rockbox.zip on your music player, reboot it and
*smile*.
If you want to build for more than one target, just create several build
directories and create a setup for each target:
$ mkdir build-fuzeplus
$ cd build-fuzeplus
$ ../tools/configure
$ mkdir build-xduoox3
$ cd build-xduoox3
$ ../tools/configure
