One thing I noticed is that when I run readelf with -s I don't see the symbol I'm referencing. I see others like __bss_start Here is the linker script portion that declares my symbol: .cpu_memory_data : { PROVIDE (_alt_partition_cpu_memory_data_start = ABSOLUTE(.)); *(.cpu_memory_data) . = ALIGN(32 / 8); PROVIDE (_alt_partition_cpu_memory_data_end = ABSOLUTE(.)); } > cpu_memory_data Here is the output of nios2-elf-readelf -s re/ssec/Debug [SOPC Builder]$ nios2-elf-readelf.exe -s project.elf | grep partition 373: 11000000 0 NOTYPE GLOBAL DEFAULT ABS _alt_partition_cpu_memory 1617: 11000000 0 NOTYPE GLOBAL DEFAULT ABS _alt_partition_cpu_memory I am referencing these symbols in the code: extern char _alt_partition_cpu_memory_data_start[]; extern char _alt_partition_cpu_memory_data_end[]; printf("start:%p end:%p\n", _alt_partition_cpu_memory_data_start, _alt_partition_cpu_memory_data_end); which works. Should this symbol show up in the readelf output? Thanks, Dan
