nwsp2 lite - stock Seagate AF HD 2TB not booting correctly

[frenbu]

ok i'll try it in the late afternoon after work !
I hope the console output will give us more info on the issue...

have a nice day, frenbu

[frenbu]

now we got him, the kernel boot hangs during ehci usb bus registration!
it stops here:

Code: Select all

...
...
mv643xx_eth_port mv643xx_eth_port.0: eth0: link up, 100 Mb/s, full duplex, flow control disabled
console [netcon0] enabled
netconsole: network logging started
aoe: AoE v47 initialised.
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
orion-ehci orion-ehci.0: Marvell Orion EHCI
orion-ehci orion-ehci.0: new USB bus registered, assigned bus number 1

Here the full boot log: http://pastebin.com/2kwVWqcm

So the problem is the usb hub..... I'm trying to figure out the correct kernel parameter to blacklist the module loading, maybe rdblacklist?
good one!

[fvdw]

finally some progress.
Need to look at this if is the registering of the platform then I can disable it in the kernel but that would mean no support for usb bus anymore...

[frenbu]

i've found the correct kernel parameter: nousb

after this the boot go straight as hell and i can telnet the box with the ip you coded in the image!
now i'll try the same with the standard kernel to see if it boots... i'll update you in a while

:thumbup :punk

lets see what that brings, learned again something didn't know this nousb kernel parameter

[frenbu]

BOOTED! - with the Seagate stock HD!

:beer:

i think this evening i'll get drunk ;) i wish to offer you a beer or two ahah
mmm... what should i do in the u-boot to set permanently the parameter?

[fvdw]

success :bananadance at least you can use it now although it will lack usb support
I will take also a beer this evening to celbrate this victory

You have a nwsp2 Lite, that has a more recent bootloader and should support "the backdoor"
If you set when talking to u-boot the environment variable "LaBackdoor", then u-boot will not set the default value for bootcmd.
So you can define it yourself
For instance like this

Code: Select all

setenv LaBackdoor open
setenv bootcmd run fvdw_boot
setenv fvdw_boot 'ide reset; diskboot 0x800000 0:6; setenv bootargs console=ttyS0,1152000 root=/dev/sda7  ro reset=$(resetFlag_env} nousb; bootm'
saveenv

(Notice the capital letters in LaBackdoor)

[frenbu]

great!
I'll try that tomorrow morning, now it's beer time ;) see y!

[frenbu]

I've set the backdoor and modified the boot commands, now the nwsp2 boots always fine! :punk

Thank you fvdw, without your help and experience I would be stuck at the beginning... :hail

:thumbup glad to hear it is working now and it was a nice challenge :vhcool
It learned me something more on booting using clunc and making a rescue kernel. That knowledge we can use for other problems as well.
