Re: Re: Change FEC and SCC1 sequence,But SCC1 not work?

Wolfgang Denk:
       Thanks a lot!
       My bootargs is "setenv bootargs root=/dev/ram ip=10.32.5.17:10.32.5.15::255.255.0.0:bug
:::off"
       Today,I found fec device down when linux kernel running ,but I can see "eth1(fec ethernet)"  status with "ifconfig" command,I checked linux kernel and found fec device down when kernel running.

       After debugging,I found linux kernel close the device when  running "ip_auto_config()" function  in "net/ipv4/ipconfig.c",then, I deleted "ic_open_devs()" funtions, AND EVERYING
WORKS WELL!

      But why  do it be added to Linux kernel?

      Best regards,
      Michael.  Z.

Briefly, my platform is MPC860T from Motorola. I'm using ppcboot
1.1.16 to tftp the kernel 2.4.4 through FEC and then load
NFS/RAMDISK. If I configure the kernel with only FEC, then
everything works well(NFS works and ping through eth0 works). If I
configure the kernel with both FEC(as eth0) and SCC1(as eth1),it
works well too,but when I configure ther kernel with both SCC1(eth0)
and FEC(as eth1) (net/setup.c)! . I try to ping out through
FEC(eth1), I get ring buffer dumps and no ping response:

Please post the "Kernel command line" as printed when your kernel
boots. You did include a network device parameter in your ip= boot
argument, didn't you?
