11 EDK - "ERROR:EDK:373 - ".vectors" section has to be aligned on a 64K boundary..."

Description

The vector table for the PowerPC405 must be placed on a 64K boundary. If a linker script is generated, placing the vector table in a memory that is not on a 64K boundary or is not 64K in size, an error occurs stating the following:

"ERROR:EDK:373 - ".vectors" section has to be aligned on a 64K boundary. Please select a suitably aligned memory for this section."

Solution

This is a known limitation of the PowerPC405.The default memory chosen for a section in the linker script generation tool might not be appropriate for a particular design.If you receive this error, be aware that the section can be placed in any memory that is on a 64K boundary; this includes the IOCM memory, SRAM, DDR, or block RAM.Be aware that the vectors section should be placed near the text section to prevent errors similar to the following:

"In function '_vector0500': /myproject/ppc405_0/libsrc/xilkernel_v4_00_a/src/src/arch/ppc/
entry405.S:621: relocation truncated to fit: R_PPC_REL24 against symbol 'scheduler' defined
in .text section in /myproject/ppc405_0/lib/libxil.a(sched.o)"
