Multiple Ethernet Ports on Xilinx FPGA

Multiple Ethernet Ports on Xilinx FPGA

[Brett McNerney]

[-- Attachment #1: Type: text/plain, Size: 562 bytes --]

I currently have a custom board that we have successfully booted Linux on
and gotten telnet and ftp over a single Ethernet port to work.  What I would
like to do now is have it boot and use both the Ethernet ports located on
the board.  I have looked at the adapter.c file but was unsure how to go
about making this work.  I have searched around online to see if I could get
an idea how to do this but have not had any success in finding an answer.
Any help would be greatly appreciated.  And oh ya by the way I am working
with the 2.4.26 kernel.

Thanks

Brett

Hi All,

        Iam trying to port linux on an mpc8xx processor. Iam using 2.6.10 kernel and busybox 1.0.0.The system is booting up but its failing at the "init".For some reasons it says Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

 <0>Rebooting in 180 second

Pls check below the entire text.

Are all the libraries present for init?
# readelf -lh sbin/init
should contain a line similar to the following: [Requesting program
interpreter: /lib/ld.so.1]
If this is missing the kernel will fail to run init with the above behavior.

Re: fialing @ executing /sbin/int in main.c

[Abdul Rahaman]

Hi srideep ,

I tried putting hello world program in Ramdisk image.It is Ok.
But its not busy box link, but just object file.

I tried creating helloworld program also as busy box link, coudnt create.
perhaps u can tell me some tip to create hello world program as busy box
link.

Then i will head towards init , can tell clear what did you mean , you took
init from package , but not from busy box,
do you mean you have selected init from linux package!!!

Regards,
Rahaman

Are all the libraries present for init?
# readelf -lh sbin/init
should contain a line similar to the following: [Requesting program

If this is missing the kernel will fail to run init with the above behavior.
