Hi all
I want to port u-boot on our company new board.
I request you to find me a closer matching board,
So that I can use it as a reference.

My board's specs are :

CPU is MPC 8260
4MB Flash at cs0
128MB SDRAM at cs1
512K DPRAM at cs2
512 NVRAM at cs3

ARINC 429   at cs4
DDC 1553    at cs5
uart        at smc1

No PCI Bus.

I request your help in proving some pointers for porting u-boot for this type of board.

Thanks in advance

Suresh Chandra Mannava.

These are not "specs". This is a useless summary.

CPU is MPC 8260

==> So you can use any 8260 baed board. Just search the Makefile for "mpc8260".

You don't bother to mention anything about chip types, bus width, or any other relevant parameters. All boards have flash and RAM, so you can use any one as model.

ARINC 429 at cs4

That's a databus protocol, not any type of chip.

DDC 1553 at cs5

As far as I know, DDC is a mnaufacturer and "1553" is probably MIL-STD-1553; there are several chips around to support this.

Standard for 8260.

No PCI Bus.

Of course not, as there is no PCI controller on the 8260.

Such help is impossible, as your did not provide any useful information.

Best regards,

thank you for your comments.

that's ok. I am not aware of board full specs,
I am presenting some information which I have.

FLASH - AT49BV162
DPRAM - CY7C0832V 16bit
SDRAM - MT48LC32M16
NVRAM - M48T512Y 8bit
ARINC 429 - DD42900FP-200 16bit
1553 terminal - BV-64843F8-210 16bit

After discussing with hardware designer, I will be in a position to present more information
of this board.

once again, I request your help in proving some pointers for porting u-boot for our board.
