Hello everybody, I've been making a led-test program for my 68040 target. Everything compiles fine (both the making of the cross-compiler and the test program). However, the linker-script i'm making has a few problems. (caused by me no doubt.) I got a flash rom and some ram in my board. The first 4 bytes of the flash should be the stack-pointer (0x0B40000), the following 4 bytes should be the start address of my program ('main', which should be at 0x400). I have been looking at the info-pages of the 'ld', but i don't really know how to force those constants at 0x0 and 0x4. This might be somewhat a newbie question, but i'm kind of stuck to be honest. I will include my linker script with which i'm toying at the moment. ----8<-------- OUTPUT_ARCH(m68k) /* Specify the output machine architecture to be m68k. */ OUTPUT_FORMAT(ieee) /* Output format. Should be srec (S-records).*/ /* Same as the --oformat command-line option. */ PROVIDE (__stack = 0x0B40000); ENTRY(main); MEMORY { /* Flash; Read-only, execute */ rom1 (rx): ORIGIN = 0x0, LENGTH = 512K /* Internal SRAM; RW, no execute */ ramcode (rwx): ORIGIN = 0x800000, LENGTH = 2048K ramdata (rw): ORIGIN = 0x0A00000, LENGTH = 2048K } SECTIONS { .vector0 : { . = 0x0} = __stack; .vector1 : { . = 0x4} = &main; .text : { *(.text) } > rom1 .data : { *(.data) } > rom1 .bss : { *(.bss) end = ALIGN(0x8); } > ramdata } ----8<--------- Best regards, and thanks, Jan Vermeulen ------ Want more information?
