Ok. Now I'm getting these errors when compiling RedBoot:

It looks like my memory mapping is not configured properly. Here the
configuration files go:

-- mlt_arm_sa11x0_accelent_ram.h --

// eCos memory layout - Fri Oct 20 05:56:24 2000

// This is a generated file - do not edit

I don't know if it's make sense, but I've tried it for the
mlt_arm_sa11x0_accelent_ram.ldi file and it also didn't work:

// eCos memory layout - Fri Oct 20 05:56:24 2000

// This is a generated file - do not edit

#include <cyg/infra/cyg_type.inc>

MEMORY
{
    ram : ORIGIN = 0x80000000, LENGTH = 0x2000000
}

SECTIONS
{
    SECTIONS_BEGIN
    SECTION_fixed_vectors (ram, 0x80000020, LMA_EQ_VMA)
    SECTION_rom_vectors (ram, 0x80020000, LMA_EQ_VMA)
    SECTION_text (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_fini (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_rodata (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_rodata1 (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_fixup (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_gcc_except_table (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_data (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    SECTION_bss (ram, ALIGN (0x80000004), LMA_EQ_VMA)
    CYG_LABEL_DEFN(__heap1) = ALIGN (0x80000008);
    SECTIONS_END
}

Thanks again,
Cristiano.
