[U-Boot-Users] Choosing flash and ram for embedded mpc5200 and loading flash

[mike ingle]

1.  I am designing in a MPC-5200 loosely based on the MPC-5200 LITE.
2.  I plan to keep the ethernet the same.
3.  I plan to keep the serial console the same.
4.  I would like to use 2 : K4H511638B-TC  Samsung  32Mx16 DDR memory 
	Any comments?  Am I asking for trouble?
5.  I would like to use Toshiba 16Mx8 NOR flash TC58FVM6T2ATG-65.  It
uses common flash interface.  
	Any comments?  I am choosing this over the AMD flash in the reference
design based on availability.  

Finally, I have a MPC-823 set up as a JAM player over JTAG for use with
Altera parts.  Is there any way to move the u-boot image to a JAM file
which could then be loaded via the MPC-5200?  I am trying not to have to
purchase the BDI-2000.  I suspect that I could also use my FPGA (I will
have an Altera cyclone device connected on the local bus) as a flash
programmer by porting the programming algorithm from the NIOS reference
board, and having pins connected to the necessary Flash pins.

On a scale of 1 - 10 how useful is the BDI-2000  10 being no one will be
able to help me at all without it.  For reference, I am one of those
people who never use a debugger.

You may see  some  50%+  better  perfromance  than  on  the  standard
Lite5200.  You may want to have a look at the icecube_5200_DDR_config
settings in the U-Boot tree.

No problems.

Reconsider. This is the  only  item  in  your  plan  where  I  really
recommend to reconsider.

You _can_ do many things, if you have enough time and nerves. You can
re-invent gthe wheel again and again and again, or  you  can  nail  a
piano  to your kneecap. Some people actually like doing these things.
I rather get a project done as smoothly and reliable as possible.

If you never use a debugger that you will not use the BDI either,  so
it's 0 for you. For me, ist's something between 10 and 20.

I very, very rarely use the BDI for debugging, but I _LOVE_ it for
programming flash.  I would rank it as a 8 on your scale.  Unless you
are a unpaid software slave (been there, done that :-), the time you
spend making a "JAM file" (whatever that is) and programming the flash
parts by hand (writing a custom program to drive the "JAM player") will
easily pay for the BDI2000.

In addition, the BDI2000 is insurance: if you ever need it just once to
single step one line of code, you will have it and be able to do that.
That one step of one line of code can easily save you from becoming a
stark raving lunatic (been there, my wife says I'm still there ;-).

The "JAM Player" has not come up on this list before, so chances are you
will be even lonelier than the VisionICE people :-/.  It appears to be a
Windows-only solution.  Two strikes against JAM: you likely won't get
any help at all.
