Ya tengo el u-boot arrancando desde la memoria nand de un ad1018 con SoC BCM6328.
El cferom.bin, de 16KB, lo he grabado en el bloque 0 de la nand y a un u-boot.bin renombrado como cferam.000 le he añadido 12 bytes de cabecera con la dirección de entrada de memoria.
Este cferam.000 se lo he pasado al mkfs.jffs2 para que creara una imagen JFFS2 y la he grabado en los bloques 1,2,3,4 y 5 (ocupa unos 600KB)
Vamos, lo que se hace con el cferam.bin lo he hecho con el u-boot.bin.
Al u-boot.bin le cambié en el make menuconfig la dirección de entrada (CONFIG_SYS_TEXT_BASE) de 0x80010000 a 0x80600000, porque la primera me machacaba los punteros debido a que un cferam es bastante más pequeño.
Pero no se cómo añadir al cferom.bin los datos por defecto de la NVRAM cuando compilo ¿Alguna idea?
Un saludo
