| 00:26.44 | Dufflepod | Not using a linker script file. Doing it on the assembler command line. objdump shows the correct sections base and length I'd expect. |
| 00:26.50 | Dufflepod | [ sorry for the delay then ] |
| 00:30.47 | Dufflepod | Though there may be some wierd glitch because I'm cross assembling for the ARM target on i386/Linux, so I rebuilt the binutils toolset earlier. Needless to say it had no effect. |
| 00:58.55 | joe_bleau | Here's what I use on microcontroller projects: $(OBJCOPY) -R .stack -S -O binary $(PROJECT).elf $(PROJECT).bin |
| 00:59.48 | Dufflepod | I'll give it a spin....... |
| 01:01.39 | *** join/#edev JoeLlama (n=snork@206.169.63.10) |
| 01:03.21 | joe_bleau | objdump -x shows that I have .text .data .jcr .bss .ARM.attributes .comment in my .elf files. |
| 01:03.34 | Dufflepod | Still 0 length bin file output. I don't have a stack section in the ELF as I use noexecstack in the assembler & linker |
| 01:04.12 | Dufflepod | Maybe it doesn't like my ROM section name. I'll try renaming it to .text, though I've never had to do this before. |
| 01:05.05 | Dufflepod | Ta-daaaaah! |
| 01:05.46 | Dufflepod | It wanted the section name to be .text. No doubt I could have over-ridden that with either a linker script or suitabel command line switches, but that's what the problem was anyway. |
| 01:08.08 | MonMotha | I think when it does the copy, it assumes you want .text unless you otherwise specify |
| 01:08.14 | MonMotha | since that's normally "the program" |
| 01:08.24 | MonMotha | I guess it'll also put .data and .rodata (if present) in their proper places |
| 01:09.22 | Dufflepod | Yep, I wonder if there's a bug in the --only-section <name> handling in objcopy as I've tried various permutations this evening |
| 01:10.48 | Dufflepod | This was a pure assembler bootstrap prog for the bottom of the flash so there was no true .data at all. That's why I hadn't bothered hacking around a linker script file. |
| 01:11.57 | joe_bleau | Maybe it wasn't marked as executable? |
| 01:12.44 | joe_bleau | Or loadable |
| 01:12.50 | Dufflepod | I changed this: .section ROM,"x" to .section .text,"x" |
| 01:13.02 | Dufflepod | Could that leading period be significant? |
| 01:13.22 | Dufflepod | Looks a bit suspicious. |
| 01:13.40 | joe_bleau | Run objdump -h on both and see examine the diffs? |
| 01:14.03 | Dufflepod | Good idea |
| 01:14.36 | MonMotha | section names do typically begin with a ., though I'm not sure binutils actually cares |
| 01:17.01 | Dufflepod | Interesting result of the objdump -h comparisson.... |
| 01:17.10 | joe_bleau | I changed my section from .text to ROM, no problems. |
| 01:17.51 | Dufflepod | The .text sections is flagged CONTENTS, ALLOC, LOAD, READONLY, CODE |
| 01:18.12 | Dufflepod | The ROM section is flagged CONTENTS, READONLY, CODE |
| 01:19.01 | joe_bleau | Mine lost READONLY when going from .text to ROM |
| 01:19.26 | Dufflepod | Going from ROM to .ROM makes no difference here. Looks like all the magic is done by .text |
| 01:21.05 | joe_bleau | I'm golden with either .text or ROM (but I do have a linker script) |
| 01:21.24 | Dufflepod | I suppose the moral is to either use the common section names, or have a bare bones linker script ready for small progs like this one. |
| 01:21.37 | Dufflepod | Linker scripts. They're the future :-) |
| 01:21.52 | Dufflepod | Thanks for bouncing the ideas around with me. That really helped. |

| 01:36.46 | adyer | i think you may have to make some sections with the 'load' flag like this --set-section-flags=.ppcenv=contents,alloc,load,data |

| 09:58.27 | HcE | The core are completely different for starters |
| 09:58.39 | HcE | hmmm, did I feed the troll? |
| 10:01.51 | KazaLite | no....im not troll |
| 10:01.58 | KazaLite | was just busy in googling |
| 10:02.47 | KazaLite | what i can see is just 3 points....1-design is different 2-instruction set is different 3-assembly language is different |
| 10:04.46 | KazaLite | are processor registers of mpc, mips and arm similar? |
| 10:04.54 | KazaLite | like R13,14,15? |
| 10:14.15 | HcE | MIPS has IIRC 32 registers, while ARM only has 16 |
| 10:14.25 | HcE | but I guess it will depend on the chosen core |
| 10:14.32 | HcE | MIPS also comes in 64-bit variant |
| 10:15.15 | HcE | the name of the register is not really relevant, it is more its usage |
