Why is the NAND flash size in P1022DS_init_sram_flash.tcl file 64K ?

[nishad_kamdar]

I am trying to bring up a custom P1022 board which has a 1GB Nand flash connected to P1022.

I referred to the P1022DS, which also has a 1GB Nand flash.

But when i opened the tcl script, the size of the LAW window for the NAND flash is configured to only 64K.

Why is that???

Thanks for your time and support.

Hi,

The NAND flashes aren't memory mapped (as NOR flashes) - for that reason in the intialization (TLB/MMU, LAW, eLBC CS) we're mapping only a small section SRAM eLBC controller used for programming the NAND flash (you can take a look into the processor reference manual for full details).

Regards,

Marius
