I have generated the BSP by EDK 8.1.1 for my project in ML403(hardcore 

Temac and PLB Temac included). I noticed that there is a directory
called 

Xilinx_gige in the directory of /drivers/net. Is this the driver for 

MontaVista Linux2.4.20?

 

Yes, this is the PLB TEMAC driver for Linux 2.4.20.  In EDK 8.1.x, the
temac driver and Makefile are copied to drivers/net/xilinx_gige.  This
xilinx_gige directory is not available in the MVL 3.1 Preview Kit, only
in the full Professional kit.  We put the temac driver here mostly to
take advantage of the JUMBO_FRAME_SUPPORT in kernel configuration.

 

 I copied the BSP and overwrote the original one in 

the linux kernel directory (in the kernel directory, there is only a 

directory called Xilinx_enet, no Xilinx_gige. So I just copied 

Xilinx_gige.). However, my problem is in the menuconfig item of Network 

Device Support->1000Mbit ethernet, there is not any option to choose and


enable the Xilinx on-chip ethernet. Is this a problem of MontaVista
Linux 

3.1 Preview Kit, or my problem?  And What shall I do to enable the
tri-mode 

Temac in my platform? Thanks for your answer. 

 

Our best recommendation is to use the drivers/net/xilinx_enet directory
for the temac driver and just enable the Xilinx 10/100 Ethernet in
menuconfig.  If you want jumbo frame support, modify adapter.c in the
driver to define the CONFIG_XILINX_GIGE_JUMBO constant.

 

Note that Linux 2.6 support for the temac should be available from
MontaVista soon and a driver was pushed to this mailing list in March.
There will be support for MV Linux 2.6 in EDK 8.2.1 (around August).

 

 

Thanks,

Rick
