RE: [ECOS] about porting ecos in S3C4510B development board

Hi Jonathan,

   can you give me one example on how to modify the RAM base address? I
tried but still got the same problem.

   The following are my *.ldi and *.h files:

#include <cyg/infra/cyg_type.inc>

MEMORY
{
    ram : ORIGIN = 0, LENGTH = 0x2000000
    rom : ORIGIN = 0x2800000, LENGTH = 0x200000
}

SECTIONS
{
    SECTIONS_BEGIN
    SECTION_rom_vectors (rom, 0x2800000, LMA_EQ_VMA)
    SECTION_text (rom, ALIGN (0x1), LMA_EQ_VMA)

    SECTION_bss (ram, ALIGN (0x4), LMA_EQ_VMA)
    CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
    SECTIONS_END
}

Your RedBoot is using quite a bit of RAM, and the RAM app is built to use
an address within it. You need to change the RAM base address in the mlt
files.
