Regd the memory section eCos1.3.1



    The following is in the file "mlt_powerpc_vpc_ram.ldi" in
"install/include/pkgconf" directory.

SECTIONS
{
    SECTIONS_BEGIN
      .
      .
      .

    SECTION_text (ram, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_fini (ram, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_rodata1 (ram, ALIGN (0x8), LMA_EQ_VMA)
    SECTION_rodata (ram, ALIGN (0x8), LMA_EQ_VMA)
    SECTION_fixup (ram, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_gcc_except_table (ram, ALIGN (0x1), LMA_EQ_VMA)
    SECTION_data (ram, ALIGN (0x8), LMA_EQ_VMA)
    SECTION_sbss (ram, ALIGN (0x4), LMA_EQ_VMA)
    SECTION_bss (ram, ALIGN (0x10), LMA_EQ_VMA)
    CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
    SECTIONS_END
}

   Here,
     
          SECTION_rodata(ram, ALIGN (0x8), LMA_EQ_VMA)
    
    is a READ_ONLY section in ram area. Means it is defined as  READ_ONLY
in the linker script.

   Is it possible in ecos to make a READ_ONLY area READ_WRITE and then
reassign it's type to READ_ONLY from within our application?

   This is required because we want a section be READ_ONLY, on demand when
we want to write something to this area, we want to make it READ_WRITE and
after modification we want to be READ_ONLY once again.

   Is this is possible in eCos(1.3.1)? If possible, please let me know and
please also tell me how to do it.

Regards,
Prabal
