CFE para BROADCOM BCM963xx

     Vamos a compilar un nuevo CFE para Broadcom 96348GW-11, (probado en router Comtrend CT-5361).
     CFE original del CT-5361:

CFE version 1.0.37-0.7-1 for BCM96348 (32bit,SP,BE)
Build Date: Thu Apr 28 12:04:28 CST 2005 (root@jyang.linux.comtrend.com)

     Vamos a trabajar plataforma Debian 6, necesitamos una plataforma con kernel 2.6.2:

     Necesitamos los fuentes y el toolchain para la plataforma BCM96348GW-11, que vamos a descargar con git:

#git clone git://github.com/Noltari/cfe_bcm63xx.git

     Editar el fichero build.sh y cambiar de las macs el número que manejar y su base address, colocar la mac address adecuada:

hostTools/nvramembed -b "96348GW-11" -n 4 -m 11:22:33:44:55:66 -i cfe6348.bin -o cfe6348-nvr.bin

     Cambiar por:

hostTools/nvramembed -b "96348GW-11" -n 11 -m 00:1d:20:xx:xx:xx -i cfe6348.bin -o cfe6348-nvr.bin

     Ejecutar build.sh.

#./build.sh

     Y tras compilar:

nvramembed: Embed the NVRAM with the following inputs:
Board id : 96348GW-11
Number of Mac Addresses : 11
Base Mac Address: : 00:1d:20:xx:xx:xx
Memory size : 16MB
Input File Name : cfe6348.bin
Output File Name : cfe6348-nvr.bin
CFE size is 61868
NVRAM CRC = 0x9664f4e
cfe6348-nvr.bin CFE with embedded NVRAM
successfully created.

     Copiar cfe6348-nvr.bin y renombrarlo a CFE.BIN

# cp cfe6348-nvr.bin CFE.BIN

     Y ya podemos grabar nuestra flash a través de Jtag.
     El resultado es:

CFE version 1.0.37-6.4 for BCM96348 (32bit,SP,BE)
