MPC5xx now with MMU

MPC5xx now with MMU

[Geir Frode Raanes]

Has anyone kept an eye on the Motorola Automotive PowerPC group
lately? Apparently their line is upgraded with parts with MMU:

 http://e-www.motorola.com/webapp/sps/site/taxonomy.jsp?nodeId=01M98648

At the bottom there is now a MGT5100 PowerPC chip that has lots of
System-on-a-chip goodies, like DDR, 100Base-T, USB, PCI and an ATA
port. At 250 MHz. So unless one really need the QICC serial ports,
this is a interesting part indeed. The User Manual claims 603
conformity and lists Linux among its operation systems support -
but is this the doing of 'our' developers or is it an Motorola SPS
port? Or does it just lend on the fact that 603 itself is supported?

More of Motorola's automotive processors are now claiming "603 core"
processor.  It appears as this block in diagrams without any further
details.  I have a number of outstanding questions to the group
trying to get details on this block.  Things like MMU and FPU are
in the questions, and there are other details about processor
registers that I have asked as well.

I have received some requests for Linux on these new processors,
but so far no one has provided a board for me to use for development.

Thanks.

Yes, I keep an eye on the MGT5100 since its announcement. Since few days I
even have a board from Motorola with that most interesting MCU. It's
simply called "IceCube - MGT5100 Evaluation Board" and has all you need
for a nice embedded Linux system on chip/board:

- MGT5100 ( PPC603e core )
- 8MB Flash, 64 MB SDRAM
- ATA interface
- 3.3V PCI
- Serial Port, 2 x CAN, Ethernet 10/100, USB, I2C
- up to 44 GPIO

All controllers for the listed interfaces are integrated in the MCU. The
"IceCube" is shipped with an evaluation copy of CodeWarrior for Windows
:-( . No signs of Linux in the package, but a CodeWarrior shirt and a
multi-function tool instead ;-) .

I'm not very experienced regarding the Motorola integrated controllers
what means that I can't say anything about similarities to the peripherals
in the other PPC MCUs already supported by Linux. As usual the "MGT5100
User Manual" says nearly nothing about this point.

Are there any others interested on a MGT5100 Linux port or even working on
it?

Hello Werner,

	The MGT5100 is a very interesting and attractive chip. We were(are)
interested in developing a linux system using it. Unfortunately we were
told
(as of 3 weeks ago) that we could not get it because it was only being
sold
to automobile manufacturers. The reason for this was someone paid
Motorola
to develope this chip and Motorola needed that parties permission to
release
it to everyone.

	It is strange that Motorola sells a development board with for the
chip if it is only available for a select few.

	Are you able to get the MGT5100 ? If so from who and how much does
it cost and in what quantity?

	We are interested in a linux port for this chip but only if we can
buy it and it falls within our price range. I am not sure how much we
can
contribute as none of us is experienced enough to write a device driver
yet.
We have successfully hacked others code to work with our stuff, but I am
certain that this will be more involved.

	If you find Motorola has changed their policy on selling this chip
please let us know as soon as possible because we are close to having to
make
a final decision for our next project soon.


	Its good to see we aren't the only ones who want this chip. Please
pester your Motorola representitive if any of you are interested as
well.


Thanks
