Trying to install 2.6.30-rc2

[jdonth]

I'm trying to install the 2.6.30-rc2 uImage (http://openplug.org/plugforum/index.php?topic=145.0) and need to resize my 2M uImage mtd partition to 4M.

I have been unsuccessful in resizing the partition. I have tried to resize and boot into my nfs server with the following u-boot settings:

#----- SheevaPlug U-Boot settings for NFS booting -----
# Boot the plug and interrupt auto-boot sequence
#Marvell>>
set ipaddr '192.168.1.103'
set serverip '192.168.1.91'
set rootpath '/home/rootfsv1.0'
set image_name 'uImage.sheeva.040309'
set bootargs_root 'root=/dev/nfs rw'
set bootargs_end ':::DB88FXX81:eth0:none'
set mtd0 '0x100000@0x000000(u-boot)ro'
set mtd1 '0x400000@0x100000(uImage)ro'
set mtd2 '0x1fb00000@0x500000(rootfs)rw'
set console 'console=ttyS0,115200 mtdparts=nand_flash:$(mtd0),$(mtd1),$(mtd2)'
set bootcmd 'tftpboot 0x2000000 $(image_name);setenv bootargs $(console) $(bootargs_root) nfsroot=$(serverip):$(rootpath) ip=$(ipaddr):$(serverip)$(bootargs_end); bootm 0x2000000'
saveenv
reset


But after the reboot into my nfs server my uImage partition is still 2M

root@debian:/# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 "u-boot"
mtd1: 00200000 00020000 "uImage"
mtd2: 1fd00000 00020000 "root"
root@debian:/#


Any idea what I am doing wrong?
~Joe Donth


To save having to ask another question after I can solve this:
Are the following u-boot setting correct to boot back into flash when I'm done installing the 2.6.30 uImage?

setenv bootargs 'console=ttyS0,115200 mtdparts=nand_flash:0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)ro root=/dev/mtdblock2'
setenv bootcmd 'nand read.e 0x800000 0x100000 0x400000; bootm 0x800000'
saveenv
reset

The partitioning is passed to the kernel via the bootargs.  I wrote the following explanation for another thread.

The problem you are having is the MTD1 partition is 2MB and your image is slightly larger than that.  You don't need to go all the way up to 5MB partition.  You should be able to just go up to 3MB.  I'm using 4MB since that is what almost all the documentation refers to.

In the mtdparts definition the first number is size and the second number is the starting location. So 0x00100000@0x00000000 is 1MB starting at 0.  The second partition should start at the end of the first one so 0x00300000@0x00100000 would give you 3MB or 0x00400000@0x00100000 would give you 4MB.  the third partition should start at the end of the second partition 0x00400000 if you have a 1Mb first partition plus a 3MB second partition or 0x00500000 of 1MB plus 4MB.  The size of the third partition should be 0x20000000 (512MB) minus the size of the first and second partition.  So 0x1fc00000 if the second partition is 3MB or 0x1fb00000 if the second partition is 4MB.

I use:

mtdparts=nand_mtd:0x00100000@0x00000000(uBoot)ro,0x00400000@0x00100000(uImage),0x1fb00000@0x00500000(rootfs)

Which gives me a 4 MB partition for the uImage.

When you boot with the new kernel you need to use orion_nand instead of nand_flash.

Make sure you boot up the kernel using the correct mtdparts before you write the new kernel and file system to the flash.  You really need to be running the files system from someplace other than the nand flash (nfs, sdcard, usb) before you write it to the new location that your new partitioning will specify.

Once you have decided on the partitioning you want you must always pass the same parameters to the kernel.  If you don't pass the partitioning via the bootargs, the kernel assumes a default value.  The nand flash doesn't really have a partition table.

You can display the partitions the kernel understands with:

cat /proc/mtd

[cbxbiker61]

"mtdparts=nand_mtd ..." is correct for a 2.6.22.x kernel.
"mtdparts=orion_nand ..." is correct for a 2.6.30 kernel.

So If you are booting the 2.6.30 kernel over tftp, you need to change that.  I noticed that if you boot with an incorrect mtdparts for the 2.6.30 kernel, the 2.6.30 kernel seems to figure out the "old" partitions.  Which sounds like what you're seeing.

You definately need to use "orion_nand" once you're ready to boot the 2.6.30 kernel from nand.

[jdonth]

Sorry, I didn't make myself clear.

I'm booting from nfs with the original uImage (2.6.22) and wanted to flash the 2.6.30 image to the nand from there (and the jffs2 to mtd2 at the same time).

However, I can not get a 2.6.22 uImage partition to size to 4M so that I can do the flash_earaseall/nandwrite of the 2.6.30 image.

Am I trying to do this the wrong way?

[kilowatt]

Did you set the bootargs to pass your desired partition info to uImage (2.6.22) when you booted from nfs?

[jdonth]

Did you set the bootargs to pass your desired partition info to uImage (2.6.22) when you booted from nfs?

Here is my bootargs:

set ipaddr '192.168.1.103'
set serverip '192.168.1.91'
set rootpath '/home/rootfsv1.0'
set image_name 'uImage.sheeva.040309'
set bootargs_root 'root=/dev/nfs rw'
set bootargs_end ':::DB88FXX81:eth0:none'
set mtd0 '0x100000@0x000000(u-boot)ro'
set mtd1 '0x400000@0x100000(uImage)ro'
set mtd2 '0x1fb00000@0x500000(rootfs)rw'
set console 'console=ttyS0,115200 mtdparts=nand_flash:$(mtd0),$(mtd1),$(mtd2)'
set bootcmd 'tftpboot 0x2000000 $(image_name);setenv bootargs $(console) $(bootargs_root) nfsroot=$(serverip):$(rootpath) ip=$(ipaddr):$(serverip)$(bootargs_end); bootm 0x2000000'
saveenv
reset


See anything wrong?

[kilowatt]

nand_flash needs to be nand_mtd

Your setting the uImage partition to read only which will make it hard to write you kernel.

[jdonth]

No good.

I changed the following settings:

Here is your problem:

Code:

Kernel command line: console=ttyS0,115200 mtdparts=nand_mtd:$(mtd0),$(mtd1),$(mtd2) root=/dev/nfs rw nfsroot=192.168.1.91:/home/root

Uboot is kind of tricky about expanding variables.    Your mtdparts isn't being expanded.   Reset your plug and set the console variable again.

for some reason the kernel is not getting the right bootargs.

The last line here shows the kernel command line.  It is not getting the partition table.  Seems the uboot doesn't do the substitution you have in your console setting on each boot.  Perhaps it only evaluates the bootargs for substitution and doesn't evaluate console for substitution during the bootargs substitution.

try

set console 'console=ttyS0,115200'
set bootcmd ''tftpboot 0x2000000 $(image_name);setenv bootargs $(console) mtdparts=nand_mtd:$(mtd0),$(mtd1),$(mtd2) (bootargs_root) nfsroot=$(serverip):$(rootpath) ip=$(ipaddr):$(serverip)$(bootargs_end); bootm 0x2000000'

last suggestion will work.
U-boot will only replace the env variable for the first setting i.e.
setenv y $(x)

if x==55
y will get 55
if x==$(z) and z==44
y will get $(z)

OK! Thanks for all the help so far.

I was able to boot into nfs with the resized (4M) uImage size.
I then Flashed the 2.6.30-rc2 uImage and reset the plug:

I used the following u-boot commands for the nand boot:

setenv bootargs 'console=ttyS0,115200 mtdparts=orion_flash:0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs) root=/dev/mtdblock2'
setenv bootcmd 'nand read.e 0x800000 0x100000 0x400000; bootm 0x800000'
saveenv
reset


The plug "hung" booting the kernel:


USB 0: host mode
PEX 0: interface detected no Link.
Net:   egiga0 [PRIME], egiga1
Hit any key to stop autoboot:  0

NAND read: device 0 offset 0x100000, size 0x400000

So close, any other suggestions?

[cbxbiker61]

The first time I booted after reflashing the kernel I got hung just like that.  Then I did a hard reset and it worked fine.  Yeah, your getting close....almost there.

[kilowatt]

2.6.30 needs two additional uboot parameters set.

setenv mainlineLinux yes
setenv arcNumber 2097

Also did you write your jff2 file system to flash mtd2 after changing the partitions?   

You will need to change mainlineLinux to "no" if you go back to booting  the Marvel kernel.

[kilowatt]

Since your only telling the kernel about two of the partitions on your flash, the files system will be the second one /dev/mtdblock1.  You can either change your bootargs to root=/dev/mtdblock1 or change the bootargs to tell the kernel about all 3 partitions.
