Enable network for the Intel 82551ER chip - pc386

[João Paulo Scalão Martins]

Hello guys,

I'm using the PC386 BSP on a Single Board Computer and I need to enable the ethernet interface of this SBC, so I can create TCP/IP communication for my project.

My SBC uses the Intel 82551ER ethernet chip. The PC386 BSP doesn't have the specific driver for this chip, and I have some questions:

Does the ne2000 driver support this chip? How can I build the BSP with the ne2000 driver? (the source folder of pc386 has a ne2000.c file, but it seems that this file is not compiled in the building of pc386 - am I wrong?)

Thank you!

Regards from Brazil

Joao Paulo

This NIC is supported by the libbsdport collection of add-on drivers.

Check that out from git.

No on ne2000.

It is compiled but only when networking is enabled.

Thank you Chris!

I'm trying to use the fxp driver, but I didn't understand your init.c. As a matter of fact, I don't know how to use the fxp driver, because I have not found any fxp_driver_attach_function to put on the ifconfig struct !!!

I start writing some code, just this way: 

driver_t* libbsdport_netdriver_table[] =

{

  &libbsdport_fxp_driver,

  NULL

};

When I compile the program, the compiler gives me an error "undefined reference to libbsdport_fxp_driver". This error occurs in another .c file, at the start of a function which doesn't have any relationship with the libbsdport_netdriver_table !!!! 

I checked the header <bsp/libbsdport_api.h> and the driver libbsdport_fxp_driver is defined as extern. Sounds like the linker can not found the real definition of the driver...

Best regards...

Hi Joao,

Have you checked the LDFLAGS in your makefile?

Something like this:

LDFLAGS = -lif_fxp -lbsdport

(copied from Chris' makefile.am file)

I hope it helps...

The problem was solved by adding "-lif_fxp -lbsdport" in the LD_LIBS of my MAKEFILE.

Now I have some TCP packets being exchanged between my RTEMS-Single Board Computer and a Linux Desktop.

Thank you so much, Joel, Chris and Wendell!
