While the AR9331 has a gigabit MAC towards the internal switch, the integrated PHYs however are only 100-base-tx capable. The existing code however advertieses gigabit capability in the link status word. If you attach such a PHY to a gigabit capable switch on the remote end, with some probability it attempts to negotiate gigabit and fails, falling baco to the AR9331 assuming a 10mbit half-duplex link. This has been observed quite frequently with the Carambola2 and gigabit capable switches. In ath79_register_eth(), "pdata->has_gbit = 1;" is set unconditionally for both AR9331 ethernet ports. This is most likely wrong. Despite the two MAC IP cores being gigabit MACs, the MAC for eth1 is connected to a 100base-T PHY via MII. The has_gbit attribute is used in the ethernet driver to determine the supported link modes. So either pdata->has_gbit is not set to 1 anymore, or the ethernet driver needs to be modified to determine the advertised link code word on another criteria than pdata->has_gbit. This patch implements the former solution. Signed-off-by: Harald Welte <laforge@gnumonks.org> SVN-Revision: 42432
This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
