I an designing a product using p2020cpu refering to the design of p2020rdb-pc. I have 4GB DDR, 32MB Nor Flash and no PCI. So I have to modify the memory map.In 36-bit u-boot my memory map:
0x0_0000_0000 0x0_ffff_ffff DDR
0x1_e000_0000 0x1_e00f_ffff CCSRBAR
0xf_fe00_0000 0xf_ffff_ffff NOR (0xf_eff8_0000 uboot)
I already have the appropriate 36-bit u-boot, I want to download the .bin file to my board.
I have some questions:
(1)Can I assign the address as above? Can I assign the NOR base address as I want?
(2)Do the memory windows in the Codewarrior have relationship with the memory map in u-boot? Or I can assign the address as I want?
(3)How should I assign the memory windows in Codewarrior?
(4)How should I build a project to achieve my memory map？
The steps that I download a 32-bit u-boot to p2020rdb-pc in Codewarrior is:file>new>codewarrior bareboard project wizard>board-p2020rdb-pc >others is default.In Target Task I set Target RAM 00002000-00030000,Base Address FF000000.
(5)Now should I also choose p2020rdb-pc board? How can I achieve the 36-bit?
(6)Should I modify the files such as p2020rdb-pc_init_core.tcl? How to modify it?
