The flash chip on the board (Spansion S25FL256SAIF00) is rated to support at least 50MHz for normal read requests according to the datasheet. 133MHz for fast reads. However, ramips seems to be limited to 80MHz. >From testing this, higher values do not improve speeds. time dd if=/dev/mtdblock3 of=/dev/null bs=64k from 42.82s to 14.09s. boot speed is also faster: [ 66.884087] procd: - init - vs [ 48.976049] procd: - init - Since spi speed was requested: [ 3.538884] spi-mt7621 1e000b00.spi: sys_freq: 225000000 CPU is 900MHz: [ 0.000000] CPU Clock: 900MHz Signed-off-by: Rosen Penev <rosenp@gmail.com> [fixed commit message by adding missing 0 in the spi-mt7621 clock output] Signed-off-by: Petr Štetiar <ynezz@true.cz> |

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
