Hi: While tring to bring up my mpc8270 based board, I found out the u-boot is not receiving packets (It's sending correct packet when i use ethereal for sniffing). When trying "ping", it generated an ARP packet first, the other host replied with , but the board never seems to receive it. When digging into the code, in cpu/mpc8260/ether_fcc.c file, it tries to initialize the parameter ram by :
pram_ptr = (fcc_enet_t *)&(immr->im_dprambase[info->proff_enet]);
However, I can't seems to find where the info->proff_enet got initialized. I am using u-boot-1.1.4, but the 1.1.6 code does the same thing. The ether_scc.c file seems doing the right thing, because it defined PROFF_ENET as a macro.
A bug ?
Another thing, I loaded the uImage into memory using JTAG, but the "bootm" command failed when it tries to uncompressing the kernel, error message is "inflate() returned -3". I am running u-boot in ram directly , not from the flash, I have found some posts which saids if u-boot is running from RAM, it can't uncompressing the kernel, but without any explaination on why.
Thanks lei
