This is my first post to the list. I am using u-boot-1.3.4 in buildroot-2011.11 My device is a at91sam9g20-ek I have a patch adding: include/configs/at91sam9g20ek.h which I gather acts as a config file for u-boot.
U-Boot> help does not list mtdparts
But my bootargs does use it: bootargs=mem=64M console=ttyS0,115200 mtdparts=atmel_nand:4M(bootstrap/uboot/kernel)ro,60M(rootfs),-(data) root=/dev/mtdblock1 rw rootfstype=jffs2
This mtdparts is defined for Linux kernel NAND driver.
Is there a trick to add the mtdparts command?
Yes, you need to add "#define CONFIG_CMD_MTDPARTS" in
include/configs/at91sam9g20ek.h
Or is there supposed to be a command?
I unsuccessfully added to include/configs/at91sam9g20ek.h #define CONFIG_JFFS2_NAND 1 #define CONFIG_JFFS2_CMDLINE 1 #define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c which did not result in adding the command line.
