read - write between DDR and T1024

Hi All,

I do not know how to communicate between DDR to T1024, could you support me? Thank you for your consideration.

The memory map is like that:

Memory map on T1024RDB
----------------------
Start Address End Address Description Size
0xF_FFDF_0000 0xF_FFDF_0FFF IFC - CPLD 4KB
0xF_FF80_0000 0xF_FF80_FFFF IFC - NAND Flash 64KB
0xF_FE00_0000 0xF_FEFF_FFFF CCSRBAR 16MB
0xF_F802_0000 0xF_F802_FFFF PCI Express 3 I/O Space 64KB
0xF_F801_0000 0xF_F801_FFFF PCI Express 2 I/O Space 64KB
0xF_F800_0000 0xF_F800_FFFF PCI Express 1 I/O Space 64KB
0xF_F600_0000 0xF_F7FF_FFFF Queue manager software portal 32MB
0xF_F400_0000 0xF_F5FF_FFFF Buffer manager software portal 32MB
0xF_E800_0000 0xF_EFFF_FFFF IFC - NOR Flash 128MB
0xF_0000_0000 0xF_003F_FFFF DCSR 4MB
0xC_2000_0000 0xC_2FFF_FFFF PCI Express 3 Mem Space 256MB
0xC_1000_0000 0xC_1FFF_FFFF PCI Express 2 Mem Space 256MB
0xC_0000_0000 0xC_0FFF_FFFF PCI Express 1 Mem Space 256MB
0x0_0000_0000 0x0_ffff_ffff DDR 4Gb

I thought that, I can assign an address to a pointer which defined in the main program, the address is from the range of 0x0_0000_0000 0x0_ffff_ffff DDR 4Gb and when I start to write and read this address, I can use the ddr directly. Is it correct?

I have done this method in pc, i had a segmentation fault error. Could you guide me?

Thank you for your consideration.

NXP supports only CodeWarrior IDE for development and debugging.

Please refer to the attached T1024RDB initialization script as example.
