- Subject: [ECOS] implications of placing vectors section after the text section.
Hello,
I currently have this RAM_STARTUP type memory map on a
leon cyclone platfrom ....
SECTION_vectors (ram,0x01000000, LMA_EQ_VMA)
SECTION_text (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fini (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata1 (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixup (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_gcc_except_table (ram, ALIGN (0x4),
LMA_EQ_VMA)
SECTION_data (ram, ALIGN (0x04), LMA_EQ_VMA)
SECTION_bss (ram, ALIGN (0x8), LMA_EQ_VMA)
I want to know what are the potential implications if
i move the vectors section after the text
section.. if anybody has experiemented with this
configuration.. please let me know if there
are any potential side effects.
This is the configuration i want use...
SECTION_text (ram,0x01000000, LMA_EQ_VMA)
SECTION_vectors (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fini (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_rodata1 (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_fixup (ram, ALIGN (0x4), LMA_EQ_VMA)
SECTION_gcc_except_table (ram, ALIGN (0x4),
LMA_EQ_VMA)
SECTION_data (ram, ALIGN (0x04), LMA_EQ_VMA)
SECTION_bss (ram, ALIGN (0x8), LMA_EQ_VMA)
regards,
keshav
