uboot doesn't pass bootargs to kernel
August 13, 2017 10:05PM
Hi, I'm fighting half of the day and slowly giving up.
Nsa320 with latest debian and kernel on usb stick and latest uboot with default settings (env default -a). When booting I get an error:

I edited it a bit so it shows the bootargs before booting the kernel and it seems ok.

and still the same error:
I tried it on ext4 and ext2, usb and sd card, different root parameters root=LABEL=USBROOT , root=LABEL=rootfs (changed label of course), root=/dev/sdb1, sdc1, updated uboof from 15.10 to 16.05, downgraded kernel to 4.10.9, created /boot/uEnv.txt with bootargs and manually set bootargs from commandline before run bootcmd_usb command and always the same error.
One thing which I see now is

importing envs ...
## Warning: Input data exceeds 1048576 bytes - truncated

but I don't have any Idea where it's from

Your problem seems to be quite simple. But I need to see the entire serial console log to be sure. In a booting problem like this, the entire serial console log is a must (fragments of the log is never good enough).

Re: uboot doesn't pass bootargs to kernel

@bohdi
Hi, I was using screen for serial connection and it gave me just 1 screen of output ;) this is from minicom:
Maybe as a walkaround is there a option to hardcode the commandline somewhere? I know that when compiling kernel there is an option for that. what about device tree ?

When you run my u-boot and kernel releases, there will never be needs to hardcode bootargs!

The problem was that you had the DTB embbded inside uImage. That was the reason bootargs was messed up when you load the DTB from u-boot.

Step 4 said:

Quote

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

So mount the drive on a different box and reverse the step:

cd /media/sdb1/boot
cp -a uImage uImage.nsa320
cp -a uImage.orig uImage
sync

And plug it back in the NSA320 and restart.

And by the way, this error is not important. But it indicated that you don't have the latest default envs for U-Boot 2016.05-tld-1. Either you did not flash it, or they have been changed. You shoud not see this with the latest envs.

Re: uboot doesn't pass bootargs to kernel

Will try this when I get home,
also with the ubot env i had it loaded but then flashed new uboot and reset this to default envs from uboot with env command because too much clutter and i was thinking it helps ;)
Re: uboot doesn't pass bootargs to kernel

@bohdi
Big thanks, I managed to get it running but still have an error later - the command line differs from what I have in uboot


Gave up waiting for root file system device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  LABEL=rootfs does not exist.  Dropping to a shell!


BusyBox v1.22.1 (Debian 1:1.22.0-19+b3) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) cat /proc/cmdline
console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)
and uboot generates (run set_bootcmd_usb then saveenv)
bootargs=console=ttyS0,115200 root=LABEL=USBROOT rootdelay=5 rootfstype=ext2 mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)
when I changed the label of usb drive and in uboot to rootfs it booted bot still the /proc/cmdline is different from uboot

root@debian:~# cat /proc/cmdline
console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)
For now it's not a problem, but we have to be aware of this, maybe you can add some info to the debian thread

Cool.

It is a requirement to have label named rootfs if you run the new u-boot with its default setting for bootargs root=LABEL=rootfs. Of course you can set it to anything you want in both palces.

It's in the installation instruction, you've just missed that part:

Quote

Updated 24 Jul 2017:

Basic Debian stretch Kirkwood rootfs for most Kirwood plugs:

...

1. Format a new USB drive with a single Ext3 partition, and label it rootfs. If you are running the latest U-Boot for Kirkwood then you can use Ext4.
