I'm attempting to load Linux onto a custom board that was based on the 5485EVB evaluation board. I was able to load the BSP distribution of Linux (from Freescale) onto the eval board with few problems. I pushed colilo onto the flash and just loaded the image into RAM via tftp. That all works fine. Now I need to get this onto my custom board. The primary difference between the boards is the memory map. On the eval board the memory map is reported to be: Type Start End Port Size ---------------------------------------------------------------------------------- SDRAM 0x00000000 0x03FFFFFF 32-bit MBAR 0x10000000 0x1003FFFF 32-bit System SRAM 0x10010000 0x10017FFF 32-bit Core SRAM0 0x20000000 0x20000FFF 32-bit Core SRAM1 0x20001000 0x20001FFF 32-bit Code Flash 0xE0000000 0xE0FFFFFF 16-bit Boot Flash 0xFF800000 0xFF9FFFFF 16-bit My board looks like this: Type Start End -------------------------------------------------------------------------- FLASH (8Mx32 32Mb) 0x0000 0000 0x01FF FFFF SDRAM (16Mx32 64Mb) 0x0200 0000 0x05FF FFFF I can't even find the colilo sources. I've been searching for a colilo how-to but it doesn't seem to exist. Can anyone give me a little advice here? Any help would be much appreciated.
