Booting sandpoint from ide disk

Booting sandpoint from ide disk

[Lauri Ojantakanen]

Hi,

does anyone have a good solution for booting sandpoint X3 (cpu 7410, altivec
supported) from ide hard disk? Dink32 does not seem to support anything like
that and ppcboot does not seem to support that CPU.

If you want to stay with DINK, you can put the zImage in flash and set DINK up
to automatically (or not) jump to where you put it.  The zImage will relocate
itself, uncompress the kernel (in the proper location) and then boot.  With the
correct cmdline, you can use an IDE disk partition for your root filesystem.
Unless you hack DINK, you won't be able to boot a kernel actually sitting on
the IDE disk, you have to put it in flash or get it into memory some other way
first.  As others have already said, you can always use PPCBoot.

Instant need for booting from ide disk seem to have gone away :( Dink32 does
not start anymore at all. When I restart the machine nothing comes through
the serial cable (settings are correct). I have not touched to any board
switches. Red leds on the altimus board are as follows:

RAM: not active
ROM: not active
stat: not active

Others are active.

On sandpoint main power and standby power -leds are active.

Actually when I recycle the power I get just one totally random character to
minicom (does not happen everytime).

Any ideas?

Were you trying to put the kernel in flash or something?  If you've got
access to HW debuggers (like the Abatron BDI) look at what's at
0xFF00_0000, it should start off with a bunch of nop's.

Ah, I guess I should have said, "Don't overwrite DINK" if that's what you did.
If you overwrote DINK, you'll have to find a ROM burner & a copy of DINK and put
it back on the FLASH.  After that, you can put the zImage either further back in
that FLASH where id doesn't overwrite any other code or better yet put it in the
secondary FLASH.

Actually the worst thing is that I did not write anything to flash. I was just
considering to write zImage to flash. I just shutdown the linux running on
that board (booted with bootp) to get into dink and it just did not work
anymore.

Well, I would make sure everything is properly seated stil then.

There is nothing stopping you porting PPCBoot to this CPU.  Once you have
ported PPCBoot to this CPU you could use PPCBoot...:)

PS I'm, sure you could find somebody to pay money to who would do this for
you...

Sure; we do this work all the time. It takes usually  less  than  two
weeks. Feel free to contact me.
