Boot nand impossible

« on: 27 June 2011, 09:25:51 pm »

Hi there,
I installed Squeeze on the nand of my sheevaplug, with a rootfs of Squeeze.

Code:

setenv bootargs_console 'console=ttyS0,115200n8'
setenv mtdpartitions 'mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs)'
setenv bootroot_nand 'ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs'
setenv bootload_nand 'nand read.e 0x00800000 0x00100000 0x00400000'
setenv nand_boot 'setenv bootargs $(bootargs_console) $(mtdpartitions) $(bootroot_nand); run bootload_nand; bootm 0x00800000'
setenv recover_ramdisk 'root=/dev/ram0 rw ramdisk=0x01100000,8M install_type=nand'
setenv recover1 'setenv mainlineLinux yes; setenv arcNumber 2097; setenv bootcmd run recover2; saveenv; reset'
setenv recover2 'run recover3; setenv bootcmd run nand_boot; saveenv; run recover5'
setenv recover3 'run recover4; nand erase clean 0x00100000 0x00400000; nand write.e 0x00800000 0x00100000 0x00400000'
setenv recover4 'usb start; fatload usb 0:1 0x00800000 uImage; fatload usb 0:1 0x01100000 initrd'
setenv recover5 'setenv bootargs $(bootargs_console) $(mtdpartitions) $(recover_ramdisk); bootm 0x00800000 0x01100000'
setenv bootcmd 'run recover1'

All worked very well.
I decided to boot with my usb disk, so I change Uboot. But when I would like again to boot on my nand, it didn' t work.
I type that :

Code:

setenv mainlineLinux yes
setenv arcNumber 2097
setenv bootcmd 'nand read.e 0x800000 0x100000 0x400000; bootm 0x800000’
setenv bootargs 'console=ttyS0,115200 mtdparts=nand_mtd:0x100000@0x00000(u-boot),0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)rw root=/dev/mtdblock2'
saveenv
reset

The boot begins, untill that :

Code:

Probably because my files system is formated on ubifs...

So how can I ask to uboot my files system is on ubifs ?

Thank you very much for your help, good evening.

Did you keep a copy of your environment variables from your NAND-booting Squeeze system?

There's a difference in the nand read commands in your first two blocks of code, although I don't quite understand what each block represents, since each block is incomplete.

Initially you had this:

Code:

mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs

And it worked. But then you changed it to:

Code:

mtdparts=nand_mtd:0x100000@0x00000(u-boot),0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)rw root=/dev/mtdblock2

Do you see the difference?

Hi,

For Marcus : you want my printenv when I try to boot to my nand ? :

It works, but remember, I changed uboot in order to boot on an other support, and if y type that :

Code:

The boot didn' t finish.

For sfzhi :
I haven' t this line :

Code:

mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs

But :

Code:

setenv mtdpartitions 'mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs)'
setenv bootroot_nand 'ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs'

I replaced the 2 lines by your command :

Code:

mtdparts=nand_mtd:0x100000@0x00000(u-boot),0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)rw root=/dev/mtdblock2

It don' t work :

But now I have an other problem, my plug don' t want to reboot, no blue led... I' ll solve this problem before posting again.

Thank you again for you help.

Hi,
Thank you very much for your help.

For Marcus : you want my printenv when I try to boot to my nand ?

Not really. It would be easier if you explained some things that you are so far not stating. Let's review the situation - please correct me if I misunderstand anything.

Your used the recover environment variables with a rootfs on USB stick to install Squeeze to NAND.
At this point, your system booted from NAND
Your system was stable here, this is where you should have saved your environment variables
You changed some environment variables, maybe you changed U-Boot too.
You tried changing the environment variables again, and it's no longer booting from NAND

If the above sequence of events is correct, the most important thing to do is to restore the environment variables to what they were at step (3), when it was correctly booting from NAND.

I made a mistake in my earlier post; I highlighted differences in your nand read commands, but evidently my fingers were running away from me; as sfzhi has pointed out, it is the part of the environment variable that defines the location of the rootfs that differs, and this is clear from your boot logs also.

In any event, it looks to me as though the way you have tried to reset your environment variables is more like the factory state than that required for booting from UBIFS NAND. If you didn't retain your environment variables from when Squeeze was working, try the ones here:

Hello Marcus, my problem with uboot is solved, so I can continue.

For your question (sorry I have to improve my english) :

Quote

# Your used the recover environment variables with a rootfs on USB stick to install Squeeze to NAND.

Yes, I used the sheevaplug installer, and I replace the rootfs with a squeeze rootfs. I changed Uboot like that :

Code:

Quote

# At this point, your system booted from NAND

Yes, it booted without problem, all was ok.

Quote

# Your system was stable here, this is where you should have saved your environment variables

Yes, I saved my environment, no problem to boot after.

Quote

# You changed some environment variables, maybe you changed U-Boot too.

Exactly, I made a resetenv, and changed Uboot to boot on a usb disk drive :

Code:

setenv mainlineLinux yes
setenv arcNumber 2097
setenv bootargs 'console=ttyS0,115200 root=/dev/sda3 rootdelay=10 rootfstype=ext4'setenv mainlineLinux yes
setenv charge_image 'usb start; ext2load usb 0:1 0x01100000 /uInitrd; ext2load usb 0:1 0x00800000 /uImage'
setenv bootcmd 'run charge_image; bootm 0x00800000 0x01100000'
saveenv

So with that I can boot on my usb disk drive.

Quote

# You tried changing the environment variables again, and it's no longer booting from NAND

Yes, I would like to boot again on my nand. I made a resetenv and after :

Code:

The beginning of the boot started well :

Code:

But just after :

Code:

I hope I made a good sum up. Thank you for your help, and for your patience.

See the 3rd post in this thread:

Quote from: sfzhi on 28 June 2011, 08:42:53 am

Initially you had this:

Code:

mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs

And it worked. But then you changed it to:

Code:

mtdparts=nand_mtd:0x100000@0x00000(u-boot),0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)rw root=/dev/mtdblock2

Do you see the difference?

When you set the environment variables to configure your NAND with UBIFS, you used a recover command which itself changes environment variables. It is not the configuration that you had prior to running recover1 that you should be trying to restore, rather the configuration after recover1 had done its changes.

Again, please read the post that I have quoted above.

The error is with your root= parameter in bootargs. Ideally you probably should have the same settings as listed here.

Hello,
Thank you to answer me a Sunday.

Do you see the difference?

I had written this 2 lines in my uboot environment :

Code:

setenv mtdpartitions 'mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs)'
setenv bootroot_nand 'ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs'

You would like I replace those 2 lines by :

Code:

mtdparts=nand_mtd:0x100000@0x00000(u-boot),0x400000@0x100000(uImage)ro,0x1fb00000@0x500000(rootfs)rw root=/dev/mtdblock2

?

And I have to do that during the installation with the sheevaplug installer and the Debian rootfs ?

Good afternoon.
