[u-boot] bootm command leads to "bad magic number"

[François Zeayon]

Hello there. :)
First of all, thanks for the great work and the huge support.

As my Networkspace 2 couldn't get beyond LaCie first boot page, I look for an alternative software and found this.
I installed FVDW-SL software yesterday and everything seemed OK but, after a reboot, my NAS was unreachable and led blinked red / blue for a while.

I first followed instructions here : Thwarted in attempt to install fvdw-sl-console.
I then followed instructions here : 3TB Cloudbox - does not appear on network. I did this until post http://plugout.net/viewtopic.php?p=22016#p22016 where "bootm" command led to this topic title.

I then checked FVDW-SL console help for "Flash U-Boot" and came here to get support to prevent me bricking my NAS.

That said, could I get some guidance to get this Networkspace 2 working, please ?

Thank you. :)

Indeed don't do that.

it is not an issue with the bootloader and no flashing is required.

The issue is your disk : the bootloader fails to detect it.

For this point, I'd rather you wait fvdw who is the expert for this.

Please describe more accurate what you did, did you use the fvdw-sl installer or did you install fvdw-sl on another way ?

As Jocko said red/blue flashing of the led means the disk is not recognized by the bootloader. This can mean either because the disk is defective or it has no or wrong partition table.
Defective is not likely because you mentioned you were able to install the firmware.
because you mentioned "bootm command leads to "bad magic number it means when trying to load a kernel from partition 6 this means the loading of the kernel to memory from partition 6 failed. Then bootm command will fail with this error.
Quetion when gave the command disk 0x800000 0:6 did you get output similar to this?
(the Image Name will be different as in this example and also image size)

Code: Select all

Marvell>> disk 0x800000 0:6
disk 0x800000 0:6## Valid EFI partition found ##

I would expect that you didn't get this otherwise the bootm command would not have failed



What to do? first step check your harddisk and partition table start the fvdw-sl console on your pc and choose action load standalone kernel (use kirkwood standalone kernel) and log in with the telnet client.
At linux prompt type the commands

Code: Select all

fdisk -l /dev/sda

and

Code: Select all

gdisk -l /dev/sda

And post the output that you get
The second command is needed when you have choosen GPT as partition table when running the fvdw-sl installer when you installed the firmware

If this fails (no output) then you harddisk is probably defective. If it gives output I need to see the result to judge if there is problem.
If it is a normal partition table then we can try to access the disk by mounting a partition

[François Zeayon]

Thank you for your interest, gentlemen.

I used fvdw-sl-console, loaded UIMAGE-3142-KIRKWOOD-150-standalone standalone kernel and followed the procedure, with GPT option. This took a while. I ended the procedure with the final "reboot" command and here I am.

I tried another time to load this firmware (as far as I can remember), without installing and, then, fvdw-sl-assistant found the NAS.
I shut down and restarted the NAS to confirm that it was still blinking red / blue and unknown form fvdw-sl-assistant, wich is the case.
I, then, opened this topic. :)

I re-run u-boot console procedure listed beyond the second link wrote in the first post.
Command "disk 0x800000 0:6" gave following output : "disk 0x800000 0:6" (yes, the repetition of the command).

"fdisk -l /dev/sda" gives :

Instructions, sir ? :)

[fvdw]

Partition table looks ok and the device should work if the firmware files have been written to the partitions.

Before testing the partitions lets first concentrate on u-boot console. That the console repeats the command you type is normal but you should get after that the output I posted in the example, that it founds a valid partition and the info on kernel loaded. If that output is not coming then no kernel is loaded. Typically the ide bus must be reset before being able to acces the disk. Therefor try this, before giving the disk command give the this command

Code: Select all

ide reset

If the kernel now loads try the bootm command

[François Zeayon]

Hello. :)

I did call "ide reset".
Here it goes when I try again tonight :

Code: Select all

>>ide reset
ide reset

Reset IDE:

[fvdw]

You should not replace the words ipaddr and serverip by actual ip address. (It are variable names that already have a value. If you replace them by ip numbers you get a command error like command replication

[François Zeayon]

Hello. :)

I did that too, with the same result: command replication only. I tried once more tonight.

[fvdw]

Then you must have made a mistake. Ps do not use <cr> in the command line type the total line for setenv command before hitting enter
