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.
