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
