[U-Boot-Users] Kernel hangs after enabling FCC in u-boot -mpc8560

[Junita Joseph]

Hello all,
 
I'm currently bringing up the FCC port in our MPC8560 based custom board
which has one TSEC port and another FCC port. We use u-boot-1.1.4 as
bootloader, where we have enabled FCC3.
 
When I downlaod the kernel and filesystem images through FCC system boots-up
to the prompt.
 
 
Sametime , while I download the through TSEC port, kernel hangs at a strange
point i.e before "Freeing the initrd memory". 
 
Any help would be greatly appreciated.
 
 
Following are the changes done in u-boot to enable FCC3 include/net.h to
u-boot-1.1.4 
 
1. Port configuration in board/mpc8560_g8700/mpc8560_g8700.c
 
2.
// #if !defined(CONFIG_NET_MULTI) && defined(CONFIG_CPM2) // For FCC3
support  #if !defined(CONFIG_NET_MULTI) ||  defined(CONFIG_CPM2) #include
<config.h> #if defined(CONFIG_ETHER_ON_FCC) #if defined(CONFIG_ETHER_ON_SCC)
 
Is this the way to enable FCC in u-boot? 
 
Please find the screen-dump below.
 
 
 
Thanks,
Junita
