[U-Boot] no mtdparted from U-Boot> prompt

[johns at msli.com]

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

Is there a trick to add the mtdparts command?
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.

This mtdparts is defined for Linux kernel NAND driver.

Yes, you need to add "#define CONFIG_CMD_MTDPARTS" in

include/configs/at91sam9g20ek.h

I had the impression there was also an interactive command-line tool for
mtdparts, from the u-boot prompt.

I added this to include/configs/at91sam9g20ek.h

Now it contains:
#define CONFIG_JFFS2_NAND 1
#define CONFIG_JFFS2_CMDLINE 1
#define CONFIG_CMD_JFFS2
#define CONFIG_CMD_MTDPARTS"

This post give me the impression that there should be a uboot mtdparts
command in addtion to the kernel option.

Dear John Stile,

Yes, there is.

For example:

=> mtdparts -?
mtdparts - define flash/nand partitions

Usage:
mtdparts 
    - list partition table
mtdparts delall
    - delete all partitions
mtdparts del part-id
    - delete partition (e.g. part-id = nand0,1)
mtdparts add <mtd-dev> <size>[@<offset>] [<name>] [ro]
    - add partition
mtdparts default
    - reset partition table to defaults

-----

this command uses three environment variables:

'partition' - keeps current partition identifier

partition  := <part-id>
<part-id>  := <dev-id>,part_num

'mtdids' - linux kernel mtd device id <-> u-boot device id mapping

mtdids=<idmap>[,<idmap>,...]

<idmap>    := <dev-id>=<mtd-id>
<dev-id>   := 'nand'|'nor'|'onenand'<dev-num>
<dev-num>  := mtd device number, 0...
<mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)

'mtdparts' - partition list

mtdparts=mtdparts=<mtd-def>[;<mtd-def>...]

<mtd-def>  := <mtd-id>:<part-def>[,<part-def>...]
<mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)
<part-def> := <size>[@<offset>][<name>][<ro-flag>]
<size>     := standard linux memsize OR '-' to denote all remaining space
<offset>   := partition start offset within the device
<name>     := '(' NAME ')'
<ro-flag>  := when set to 'ro' makes partition read-only (not used, passed to kernel)



=> mtdparts   

device nor0 <fc000000.flash>, # parts = 7
 #: name                size            offset          mask_flags
 0: firmware            0x00100000      0x00000000      0
 1: dtb                 0x00040000      0x00100000      0
 2: kernel              0x00240000      0x00140000      0
 3: small-fs            0x00280000      0x00380000      0
 4: initrd              0x00200000      0x00600000      0
 5: misc                0x00800000      0x00800000      0
 6: big-fs              0x01000000      0x01000000      0

active partition: nor0,0 - (firmware) 0x00100000 @ 0x00000000

defaults:
mtdids  : nor0=fc000000.flash
mtdparts: mtdparts=fc000000.flash:1m(firmware),256k(dtb),2304k(kernel),2560k(small-fs),2m(initrd),8m(misc),16m(big-fs)

It actually reads this:
#define CONFIG_JFFS2_NAND 1
#define CONFIG_JFFS2_CMDLINE 1
#define CONFIG_CMD_JFFS2 1 // Required to include cmd_jffs2.c
#define CONFIG_CMD_MTDPARTS 1 // Required for mtdparts command in uboot

But the command is not available on my system.
Would it help to post my .h or maybe my build log?

Adding CONFIG_CMD_MTDPARTS won't work, this option is not available
in this very old U-Boot v1.3.4. CONFIG_JFFS2_CMDLINE should add
mtdparts command. Please double check where you add this option and
ensure that it is not added in some #ifdef ... #elif ... #endif
construct. Depending on the CFG_USE_* build options some options
in the config file may have no effect at all.

It might help.
