need to know fallout strategy for LS 1043A processor for booting

[prasad_chormale]

Here is our query ,we are developing an product for  in which LS1043A  processor which has multicore is to be used. LS support booting from various source i.e nand flash,nor flash ,sd card etc.

From reference manual we came to know that the source for booting (for RCW loading)is to be selected by cfg_rcw_src[0:8] which are noting but  port pins multiplexed on {IFC_AD[8:15], IFC_CLE}.

In this aspect we have following 2 quires

1.Is there any other option to select the boot source other that port pin configuring  for e.g. by giving  any command or any thing else?? .

2.If we configured sd card as boot source and sd card  is not connected to the system than in this case what is the fall out strategy carried by LS. Does automatically boots from any other source or what action does it takes??.

Hi,

thanks for your help.

We are taking mpc-ls vnp-evb as reference and from its schematic which is available on nxp site we can to know that it has both nor and nand flash in the board

So our query is when the board is using nor as its fixed boot source what is the use of nand flash here.?

What all contents goes in nor flash and nand flash ?.
