LinuxPPC running on an EST SBC740 board?

LinuxPPC running on an EST SBC740 board?

[Todd C. Larsen]

Has anyone attempted to boot Linux on an SBC740 (or SBC603, SBC750)
development board from EST?  So far, it looks like one of the best
candidates for an evaluation board for the MPC740, since Motorola
no longer sells the Yellowknife X4.  I was just wondering if anyone
else on the list had experiences with this board.

The only EST boards I see mentioned in the mailing list archives
are the SBC8240 and SBC8260 boards.  I'm still waiting for technical
documentation from EST on this board, but does anyone on this list
know what PCI bridge chip it uses?

Thanks.

How about an alternative?  What about the IBM CPC700 reference
platform with a 740?

http://www.chips.ibm.com/products/powerpc/tools/600_ekit.html

There is already somebody booting a limping partial port to this
board using a 750.

Matt,

Thanks for the suggestion, but I've got some custom hardware that
I'm trying to find a close match for, and it has an MPC106 PCI
bridge/memory controller.  The EST SBC740 board has an MPC106 as
well.  Also, many PReP reference boards and PowerPC VME boards
(except for those from MCG, which use the Raven, etc.) use the
MPC106, so I'm hoping LinuxPPC running on one of these will be
similar.

The IBM boards use PCI bridge chips specific to IBM, as far as I
can tell.  Someone please correct me if I'm wrong...

EST is probably the way to go in your case then.  A shame
considering theu are WindRiver. :-/

Oh, FYI, a non-reference platform that matches your custom hardware
is the SBS Denali board (http://www.sbs.com).  It has a 740 and 106
bridge  with a DEC21x4x and DEC21554 in a cPCI form factor.

The CPC700 is no more specific to IBM than the MPC105/6/7 are specific
to Motorola.  I've worked on on boards with Raven/Hawk's, MPC105/6/7,
Galileo, CPC710, and CPC700.  The IBM bridges are by far the most
versatile bridges on the open market (Raven/Hawk aren't available
except on an MCG board).

I'm seeing a lot of boards now becoming available with the CPC700.
About the only thing missing is a DMA engine which its cousin, the
CPC710, does have.

Good luck,
