ps2 linux on usb memory

[devilinside128]

Hi, Mega Man
I can not partition the usb memory ext2, in the linux ps2, in the list of partitions or type of system is not.
Question: I use that program to partionarlo ext2, swap, fat32

[Mega Man]

You can use Windows for formating the last partition with fat32.

help pls ;O;

kernel panic:I have no root I want to scream

step 21 : crtmode=ntsc root=/dev/sda1 ro (usb memory stick
partitions: vfat32 + ext2 + swap)

kernel loader 1.7&1.8
ps2 v50001&70001

[Mega Man]

step 21 : crtmode=ntsc root=/dev/sda1 ro (usb memory stick
partitions: vfat32 + ext2 + swap)

You tried to mount a USB memory stick directly at startup. To do this you need to start using an initrd (remove root=...). Then mount the USB device and change root file system using pivot_root. This program is not included you need to copy it on your USB memory stick (See previous page).

First of all i would like to thank you for the awesome loader and tutorial , it has been very useful to me.

I am trying to install blackrhino to an USB hard drive , and i got stuck at the "pivot_root" point.I have extracted blackrhino from his tar archive and i mounted the disk , but i don't know how to use the .ps2 executable posted by pip25 (thanks to you too).

I tried to put the pivot_root executable inside the blackrhino's bin directory on the USB drive but i get an error (command not found or can't execute) when i try to execute the file (writing "pivot_root" or "exec pivot_root" in the console) from the ps2linux console launched with kloader and initrd.
That's because i have no clue , being noobish in this, to make the pivot_root command works , could you point me to the right steps to include , launch and use this command on ps2linux ?
Maybe i am failing the right command , or file permissions , or arguments to make it works , and some simple hints could solve it.

I hope this would not mind you too much , but i can't find anywhere on the net a better explanation to use the pivot_root command , and i am stuck with this situation.

Thank you all anyway , please excuse me if i did any error or i am asking for the obvious .

Go to the directory where you copied pivot_root and try to execute:

Code: Select all

chmod +rx pivot_root

This makes it executable.

Thanks for the fast help , i'll let you know the results, you are very kind.

[piffa]

Well , i did some progress so i edited the whole post :

Now after pivot_root command i can't login with blackrhino successfully , i type "login" and i insert root and blank password , but it keeps me saying incorrect login.And i can't unmount the oldroot directory , it seems that somewhat the root change isn't complete :

Here the steps i followed :


Insert an USB PEN with kloader , kernel and initrd

Boot with kloader , i remove the USB PEN after boot and then i plug the USB Hard Disk with the ext2 blackrhino partition.

Code: Select all

mkdir /newroot 

mount /dev/scsi/host0/bus0/target0/lun0/part1 /newroot

mkdir /newroot/oldroot

cp /newroot/bin/pivot_root _bin

cd /

cd bin

chmod +rx pivot_root

cd ..

pivot_root /newroot /newroot/oldroot

Now when i call the login command i get an incorrect login error , and i can't unmount the oldroot directory, it seems to me that the login command still is the original initrd one , so i doesn't recongnize me with root id and blank password.

Don't know what i can try 8(

You are already logged in as root and don't need to login again. When you type the commands:

Code: Select all

ls /
ls /oldroot

you can see if pivot_root was successfully.

Before unmounting /oldroot, you need to unmount /oldroot/proc and when you use devfs /oldroot/dev also. To work with it you need to mount proc and devfs on the new root:

Code: Select all

mount -t proc /proc /proc
mount -t devfs /devfs /dev

you can see if pivot_root was successfully.

When i type this i get the blackrhino directory list, so i think it worked.

Code: Select all

mount -t proc /proc /proc
mount -t devfs /devfs /dev

When i try to umount /oldroot/dev it says to me :" device Busy "

Mega Man , really thank you for the help you gave me , very appreciated, but i think i have to give up 'cause that's a little bit over my linux knowleadge , i can't keep bother you "babysitting" me every error i found.

Keep up your great work with kloader !!

Hello, mega man
I am in the step 18. Stoop pivot_root and copy it to the partition ext2 in the folder where I install the blackrhino. to him(you,them) I execute it and it(he,she) does not give ningun mensage, looks like all good.
Then reseteo her(it) ps2 and I load the vmlinux and desabilito the initrd.gz.



Then I edit kernel parameter and place the following thing crtmode=ntsc root=pivot_root, Boot Linux.

Aprece then a mensage of mistake " kernel panic "
Did I me can dicir that I am doing badly?

This means your finished at this point. System is running and usable. The only thing what is remaining is that you can start Linux System V init:

Code: Select all

exec /sbin/init

This will start remaining stuff.

Then reseteo her(it) ps2 and I load the vmlinux and desabilito the initrd.gz.

Then I edit kernel parameter and place the following thing crtmode=ntsc root=pivot_root, Boot Linux.

Don't do this. You are already finished above. The bad news are that you always need to do the steps above (running mount, pivot_root,...). For automatic start you can change the file "/etc/sysinit" in the initrd (see kernelloader README). Just replace exec bash by your commands entered.

[devilinside128]

Hello Mega Man
With the code "as income and the only thing that makes the ps2 is shut down until it seems comical.
What about file vmlinux?

The file "kernelloader readme", not where downloading.

We apologize for any inconvenience this will cause, but I water in a water-based. How could I say step by step I do?

Yes. I didn't see that init was already started in initrd. Init need to have PID 1.

I uploaded a initrd with replaced init.

There are 2 kernel parameters added (kernel parameters are passed to the initrd):

newroot=[USB device]
autostart=[n or time to sleep in seconds, default: 5]

autostart=n means, you need to press enter.

Hello, Mega Man.
On my PSTwo-slim SCPH-77008(PAL) this works well. Keyboard is working. But There is no "ide" or "scsi" in /dev directory(initrd.gz-ps2-20071224). I think therefore mounting usb-stick does not work: "can't mount /dev/scsi/host0/bus0/target0/lun0/part1(tried "disc","part2","disc1") device does not exist". Maybe i missed something.
Another kernel and combinations(kloader1.8, kloader1.7) starts well, but i have only blinking cursor, keyboard does not answer.
And when LIBSD module is enabled, kloader freezes on "starting modules screen".
And...Which filesystem must be on usb-stick(ext2, fat32 or reiserfs) for initrd.usb.gz?

You did Amazing work, anyway. Big thanks!

[piffa]

You did Amazing work, anyway. Big thanks!

On my 39004 i have the initrd on a FAT32 partition along with the kernel.
Kloader is in my MC instead.

Blackrhino partition has to be EXT2.

I don't know about Slim PS2 , but in my fat ps2 i have 2 usb ports and i can load pendrive only from the bottom one, did you try every USB port on your ps2 (if >1 8P).

Boot with initrd.usb.gz and the vmlinux.devfs and it pulls up the linux. next
It shows a series of errors, for example. Creating a directory in "newroot/oldroot" "read-only tile system" "boot failed rumming bash."
These errors believe that they are because it should be mounted in my "partition 2 ext2", in the partition 1 have a system vfat. is it this way mega Man?

Fearing this as hypothesis this modifies the "INIT", so that it mounts me the partition 2 ext2.

Should I modify another thing?
* By the way, when I modify the init or another thing when restarting the ps2 do they fade what modifies that I should make so that not you boren the modifications?

Then I execute the init with
exec / sbin/init
It shows the same message
"boot failed rumming bash"
but believe or it mounts the partition 2

should the pivot_root be in the portfolio where the backchino was decompressed?

* later I mount
mount - t proc / proc / proc
mount - t devfs / devfs / dev

Should the fstab modify it?

Boot with initrd.usb.gz and the vmlinux.devfs and it pulls up the linux. next
It shows a series of errors, for example. Creating a directory in "newroot/oldroot" "read-only tile system" "boot failed rumming bash."

There was an error in my /sbin/init. I needed to remount the file system writable for creating /newroot/oldroot directory. Please download initrd.usb2.gz from sourceforge. I fixed the following:

Code: Select all

mount -o remount,rw /newroot
mkdir /newroot/oldroot
mount -o remount,ro

These errors believe that they are because it should be mounted in my "partition 2 ext2", in the partition 1 have a system vfat. is it this way mega Man?

Fearing this as hypothesis this modifies the "INIT", so that it mounts me the partition 2 ext2.

I think there is no change in /sbin/init required. Just add to the kernel parameters the following:

Code: Select all

newroot=/dev/scsi/host0/bus0/target0/lun0/part2

Which filesystem must be on usb-stick(ext2, fat32 or reiserfs) for initrd.usb.gz?

Your error is not based on the file system. The USB memory stick is not detected. Please check if it is switched to be writeable. There must be a message on screen when you connect it and disconnect it. In the old initrd it is deactivated, please use "dmesg" command to get messages.

[devilinside128]

Hi, mega man
I count him that pulls up the linux with the vmlinux.devfs and the initrd.usb2.gz. next some errors are shown:
- ACTIVINTING SWAP
"modprobe: can´t open dependencies file / lib/modules/2.4.17_mvl21/modules.dep (not such file or directory) "... mega man this portfolio is not in the blackrhino "2.4.17_mvl21"

"mount - n - or remount, rw / "

"control - d will exit from this shell and reboot the system"

"not such divice or address while tring to open / dev/hda1 possibly or swap divice doesn't exist? "

..... later the screen is placed with the following thing
(none): #
... MEGA THEN CAN THAT YOU ACTIVATED THE PIVOT_ROOT.PS2
ls / oldroot



Should Maga man modify the I saw / etc/fstab, so that the partition of the swap comes out, do I have it in the partition 3, that is to say / dev/scsi/host0/bus0/target0/lun0/part3 swap?... in the blackrchino it does show the following thing:

Should it exchange the / dev/hda1 ext2 for / devhda2 swap? Here he/she doesn't go written my address "/ "?

Replace /dev/hda1 by /dev/scsi/host0/bus0/target0/lun0/part2
Replace /dev/hda2 by /dev/scsi/host0/bus0/target0/lun0/part3

To deactivate swap enter "#" at the beginning of the line, if you don't use it.

Press CTRL + D.

Note: Shutdown will not work correctly. There are some problems with the scripts in /etc/rc0.d/S31* and later.

What version of the loader and kernel should be use for my slim (77001)

1.8 + devfs + slim 77001 = usb errors ( "new usb device connected", "bulk message timeout", "unlink URB timeout", "device not accepting new address" )

1.8 + devfs + 55001 = load usb with the same result of devilinside128

It is possible that there will be a message at startup that eromdrvloader can't be started. When you see this message you need to disable the following modules:

ROM0:ADDDRV

Did you enter a white space before dev? Path names don't have white space.

To get around shutdown problem, I removed all scripts starting with /etc/rc0.d/S31* upto /etc/rc0.d/S*umountfs. To get a clean shutdown the script /etc/rc0.d/S*umountfs need to remount root read only, but there is some error before. I need to debug it.

Hi,

I'm afraid i can't use this great linux loader. I'm following the steps EXACTLY as explained on MegaMan website but I can't go even in the command line. Here is what I'm getting when booting using:

kloader1.8.elf;

vmlinux-2.4.17-ps2-20080209

It doesn't matter what combination of initrd and vmlinux i use. The result is the same. My system is 39001 with matrix infinity 1.88 and uLaunchelf 4.18. Where is my error?

Thanks for help.

My web site describes only, how to install Linux on the internal hard disc. This thread talks about installing on USB memory stick.

initrd.usb2.gz or initrd.usb.gz work only when Linux is already installed on the USB memory stick or when you remove the memory stick before the 5 seconds time out is reached.
I recommend to use initrd.gz-ps2-20071224. Please retry, the startup should look different.

[dirsors]

MegaMan, thanks for supporting me.

Unfortunately, I'm having no success. Although the linux appears to boot properly and shows no error messages, it shows me the bash "/>" but pressing any keys nothing happens, like a 'system halt'. Num and Caps Lock doesn't turn on/off. The cursor flashes at the screen but i can't interact with the command line. Yes, my keyboard is working properly ;-).

i'm using initrd.gz-ps2-20071224 and vmlinux-2.4.17-ps2-devfs-20080302. Booting from CD, DEV1 makes no difference.

Here's a snapshot just before the bash "/>" appears.

This looks like a normal boot. The jump happens, because kernel loader uses one function for loading uncompressed and compressed kernels. The size is not known before, when using compressed kernels. I decided that the graphic shows the available memory space and it doesn't show the file size correctly. Kernel loader will start it only, if it can verify that everything is loaded (by ELF headers).
USB seems to work, because the directory "oldroot" was created on your USB stick by previous experiments. Changing root to USB memory stick was also working. So it is caused by the keyboard. You can try to plug it out and in again. Or start it without and later connect the keyboard.

devilinside128 has already similar problems:

What happens is that a need modulate the UN "USBKEYBD.IRX." WITH LAUNCHELF runs it USBKEYBD.IRX and then the kloader_1.8.elf and runs on Linux and kloader_1.8.elf.

I don't understand this sentence, but maybe you speak the same native language as devilinside128.

Hello, Mega Man
I think my problem is that the blackrino is broken. could you put the download link?, what happens in official home page in this remodeling, or something like that. thanks
