From 2a83ee55b38c81df04d7d3b83d6bf68ed72936e4 Mon Sep 17 00:00:00 2001 From: WestfW Date: Fri, 10 Jun 2011 17:47:47 -0700 Subject: Add a version number to the optiboot source and binary. http://code.google.com/p/arduino/issues/detail?id=554 end of flash memory where they can be read (at least in theory) by device programmers, hex-file examination, or application programs. This is done by putting the version number in a separate section (".version"), and using linker/objcopy magic to locate that section as appropriate for the target chip. (See http://lists.gnu.org/archive/html/avr-gcc-list/2011-02/msg00016.html for some discussion on the details.) Start the version at 4.1 (the last "packaged" version of optiboot was called version 3, so the "top of source" would be 4.0, and adding the version number makes 4.1) Refactor LDSECTION in the Makefile to LDSECTIONS so that multiple section start addresses can be defined. Change the _isp makefile definitions to make the bootloader section readable (but not writable) by the application section. (This would need to be done elsewhere as well to handle all bootloader programming techniques. Notably Arduino's boards.txt Note that this change does not change the "code" portion of optiboot at all. The only diffs in the .hex files are the added version word at the end of flash memory. --- bootloaders/optiboot/optiboot_luminet.lst | 604 +++++++++++++++--------------- 1 file changed, 303 insertions(+), 301 deletions(-) (limited to 'bootloaders/optiboot/optiboot_luminet.lst') diff --git a/bootloaders/optiboot/optiboot_luminet.lst b/bootloaders/optiboot/optiboot_luminet.lst index 737d2c5..1be7e4f 100644 --- a/bootloaders/optiboot/optiboot_luminet.lst +++ b/bootloaders/optiboot/optiboot_luminet.lst @@ -3,620 +3,622 @@ optiboot_luminet.elf: file format elf32-avr Sections: Idx Name Size VMA LMA File off Algn - 0 .text 00000274 00001d00 00001d00 00000054 2**1 + 0 .version 00000002 00001efe 00001efe 000002c8 2**0 + CONTENTS, READONLY + 1 .text 00000274 00000000 00000000 00000054 2**1 CONTENTS, ALLOC, LOAD, READONLY, CODE - 1 .debug_aranges 00000028 00000000 00000000 000002c8 2**0 + 2 .debug_aranges 00000028 00000000 00000000 000002ca 2**0 CONTENTS, READONLY, DEBUGGING - 2 .debug_pubnames 00000078 00000000 00000000 000002f0 2**0 + 3 .debug_pubnames 00000078 00000000 00000000 000002f2 2**0 CONTENTS, READONLY, DEBUGGING - 3 .debug_info 000002a4 00000000 00000000 00000368 2**0 + 4 .debug_info 000002a5 00000000 00000000 0000036a 2**0 CONTENTS, READONLY, DEBUGGING - 4 .debug_abbrev 000001ac 00000000 00000000 0000060c 2**0 + 5 .debug_abbrev 0000019d 00000000 00000000 0000060f 2**0 CONTENTS, READONLY, DEBUGGING - 5 .debug_line 000004a9 00000000 00000000 000007b8 2**0 + 6 .debug_line 000004ac 00000000 00000000 000007ac 2**0 CONTENTS, READONLY, DEBUGGING - 6 .debug_frame 000000a0 00000000 00000000 00000c64 2**2 + 7 .debug_frame 000000a0 00000000 00000000 00000c58 2**2 CONTENTS, READONLY, DEBUGGING - 7 .debug_str 00000150 00000000 00000000 00000d04 2**0 + 8 .debug_str 00000150 00000000 00000000 00000cf8 2**0 CONTENTS, READONLY, DEBUGGING - 8 .debug_loc 00000194 00000000 00000000 00000e54 2**0 + 9 .debug_loc 00000194 00000000 00000000 00000e48 2**0 CONTENTS, READONLY, DEBUGGING - 9 .debug_ranges 00000088 00000000 00000000 00000fe8 2**0 + 10 .debug_ranges 00000088 00000000 00000000 00000fdc 2**0 CONTENTS, READONLY, DEBUGGING Disassembly of section .text: -00001d00
