Hi,
We are using LPC2458, which has scatter (non-continuous) SRAM memory. Now we want to assign bss section to this scatter memory. We tried to create sections as below but the same is giving linking error.
SECTION_bss (sram, 0x40000540, LMA_EQ_VMA)
SECTION_bss (sram3, 0x7FD00a00, LMA_EQ_VMA)
How can we do that? What is the reason for error?
Complete ldi file:
MEMORY
{
rom : ORIGIN = 0x00000000, LENGTH = 0x80000
sram : ORIGIN = 0x40000000, LENGTH = 0xFDE0
sram2 : ORIGIN = 0x7FE00000, LENGTH = 0x4000
sram3 : ORIGIN = 0x7FD00a00, LENGTH = 0x3600
}
SECTIONS
{
SECTIONS_BEGIN
SECTION_rom_vectors (rom, 0x00000000, LMA_EQ_VMA)
SECTION_text (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fini (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata1 (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixup (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_gcc_except_table (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixed_vectors (sram, 0x40000400, LMA_EQ_VMA)
SECTION_data (sram2, 0x7FE00000, FOLLOWING (.gcc_except_table))
SECTION_bss (sram, 0x40000540, LMA_EQ_VMA)
SECTION_bss (sram3, 0x7FD00a00, LMA_EQ_VMA)
CYG_LABEL_DEFN(__heap1) = 0x7FD03200;
SECTIONS_END
}
