[Solved] TC3.8_4 Real Time Upgrade

[Rich]

Hi MTCAT

Oh, right, sorry about that, ...

Not a problem.

... I do recall now that "sudo touch" command but I didn't realize that's what we were doing (making an empty backup file). ...

That's on me. I didn't mention it in that post, but will add that information to it.

Hi Rich,

No problem, good to know what's going on there is all.

So I tried to boot up the real time kernel and now get a different modprobe error;

modprobe: can't open 'modules.dep': No such file or directory
Failed to open /dev/ramzswap0: No such file or directory
swapon: can't stat '/dev/ramzswap0': No such file or directory

And then when it gets to loading extensions, it hangs up there again. I thought we dealt with modules.dep and modules.alias already ??

Thanks,

David

Hi MTCAT
Does it boot to a prompt? You may have to hit the carriage return a couple of times to see it.

Hi Rich,

I do see a "boot:" prompt initially but I don't seem to have a choice as to what to boot, there's no "LILO like" list to choose from or anything ?

But I just wait a few moments and then it proceeds to boot the kernel indicated as default in extlinux.conf.

Thanks,

David

Hi MTCAT
Sorry, I meant command prompt.

Hi Rich,

No, unfortunately it's getting stuck again at the "Loading Extensions" step, the boot process never gets past that when trying to boot the real time kernel, I did copy all the *-rt19-tinycore.tgz files into /mnt/sdb1/tce/optional though, unless some are still missing somehow ?

Thanks,

David

Hi MTCAT

... But I just wait a few moments and then it proceeds to boot the kernel indicated as default in extlinux.conf.

So DEFAULT points to realtime, right?
And realtime looks like this:

Code: [Select]

LABEL realtime
KERNEL /boot/vmlinuzRT1
APPEND initrd=/boot/tinycoreRT1.gz quiet home=UUID= .....
If that all looks correct, add the word  text  like this:

Code: [Select]

APPEND initrd=/boot/tinycoreRT1.gz quiet text home=UUID= ..... This will skip loading extensions. See if you get to a command prompt then.

Hi Rich,

Sorry for all these problems, the extlinux.conf is setup properly for realtime, I added the "text" entry to the APPEND line as you indicated but the boot process still tried to load extensions, and get's stuck there. I attached the extlinux.conf file here.

Thanks,

David

Hi MTCAT
Try  base  instead of  text.

Hi MTCAT
One more thing, on both entries, change this:

Code: [Select]

waitusb=5 waitusb=5:UUID="622fa3dd-62bb-43fc-a837-43021b9b3c7f"to this:

Code: [Select]

waitusb=10:UUID="622fa3dd-62bb-43fc-a837-43021b9b3c7f"

Hi Rich,

Using "base" worked !, I was able to boot into X now, and "uname -r" returns "2.6.33.3-rt19-tinycore", so we skipped loading extensions with the "base" modification ?

What now, add one extension at a time to see when booting fails maybe ?

Thanks,

David

[MTCAT]

Hi Rich,

Forgot to add, I'll change the waitusb to 10 as you instructed as well, I also forgot to do the sudo touch modification, will do both of those now.

Thanks,

David

Actually, what you booted into is called the console. X is a graphical environment.
Yes, the  base  boot code instructs Tinycore not to load any extensions.
The  text  boot code instructs Tinycore not to start  X  after loading extensions.

... What now, add one extension at a time to see when booting fails maybe ?

Attach a copy of your  onboot.lst  file and we will proceed from there.

Hi Rich,

Thanks for all the help, I had problems mounting a second pen drive, so here is onboot.lst typed out for you !

Thanks,

Hi MTCAT
So you are not running a GUI. Lets start with a simple one:

Code: [Select]

tce-load -i zsync
