| 00:00.19 | T0mW | Genesis: oh |
| 00:00.35 | T0mW | Genesis: you want the dev environ on linux, correct? |
| 00:00.43 | Genesis | heu |
| 00:00.50 | Genesis | yeap |
| 00:00.57 | Genesis | juste for compiling |
| 00:01.13 | Genesis | and other debug stuff |
| 00:01.47 | T0mW | Genesis: that is tough one. There might be some compilers now to do 8051 code on a linux host. What I have been using for years has been a DOS based compiler and I run that under dosemu |
| 00:02.10 | Genesis | oki sure |
| 00:02.21 | Genesis | i'll try |
| 00:02.23 | T0mW | Genesis: the compiler, linker and assembler are all msdos based tools |
| 00:02.24 | MonMotha | sdcc can target 8051 IIRC |
| 00:02.32 | Genesis | i saw sdcc |
| 00:02.33 | MonMotha | there are a couple of assemblers, I use as31 |
| 00:02.47 | Genesis | so no pb :) |
| 00:02.59 | T0mW | MonMotha: prolly, but I have old code that I have to maintain as well that was on the dos compiler. :( |
| 00:03.08 | Genesis | i need to learn to interface it with relay card |
| 00:03.09 | MonMotha | T0mW: ah, well, then dosemu for you I guess |
| 00:03.15 | MonMotha | T0mW: you know much about ELF bwt? |
| 00:03.16 | MonMotha | btw |
| 00:03.24 | T0mW | MonMotha: issue is not the compiler, it is the run-time libc for 8051 |
| 00:03.45 | MonMotha | T0mW: ah, I don't know that the sdcc stuff comes with much of a libc |
| 00:04.04 | T0mW | MonMotha: enough to know that objcopy is your friend. |
| 00:04.46 | Genesis | thx T0mW |
| 00:05.01 | T0mW | Genesis: why not get a small 32bit ARM processor, like the Philips LPC2000 family? You can use gcc + binutils on it and the processors are really cheap |
| 00:05.31 | Genesis | i've |
| 00:05.43 | Genesis | too complex to make this correct for the moment |

| 00:08.00 | MonMotha | T0mW: well, I'm doing something silly here. I have a linux binary I need to figure some stuff out about. I uses files that are in some obfuscated format, but, due to thel ibs it links against, are I'm pretty sure fairly standard under the hood |
| 00:08.07 | T0mW | Genesis: the chips have their own built-in bootloaders to program the Flash, JTAG for debugging, most people use a wiggler |
| 00:08.29 | T0mW | MonMotha: then objdump it |
| 00:08.29 | MonMotha | there are some references to various procedures within the binary that look interesting, but none of my tools see them as debugging symbols |
| 00:08.43 | MonMotha | tried it, doesn't even know where procedures begin or end |
| 00:08.52 | T0mW | MonMotha: then it is not elf |
| 00:08.53 | CosmicPenguin | you should be able to see the calls, though, right? |
| 00:09.01 | MonMotha | T0mW: it's most certainly elf |
| 00:09.03 | Genesis | i need to know what is a wiggler ? |
| 00:09.05 | Genesis | i need to write an automaton core in pure C |
| 00:09.05 | MonMotha | at least the beginning is |
| 00:09.21 | Genesis | and a compiler to the code |
| 00:09.44 | MonMotha | it's a 100% valid x86 linux binary. I can run the darn thing, at least partialy (it needs to use X but has issues talking to my X server). If it ran 100%, I'd just chuck a debugger on it and watch it |
| 00:10.02 | MonMotha | though without full symbols, even setting breakpoints is hard. I can at least see where it calls libraries |
| 00:10.22 | T0mW | Genesis: google on "jtag wiggler", but get on the Yahoo LPC2000 group and search for info there. You simply use an ARM7TDMI gcc cross-compiler to build your target code |

| 00:21.01 | MonMotha | though the stuff that's near each other makes sense |
| 00:22.04 | MonMotha | their ENC3 encoded files are, I believe, some sort of obfuscated PNG |
| 00:22.04 | T0mW | normal symbolic tables have a symbol text name, followed by line number(s) and address location fields. That dump only has textual data. |
| 00:22.24 | MonMotha | correct. ENC3 I think is used in that case as a string for magic header comparison |

| 00:32.53 | T0mW | MonMotha: I know |

| 16:48.50 | prpplague | CosmicPenguin: checked some code into cvs, check it back out, patched it, now i want to check it back in, but the patch has added several files, is there an easy way to get cvs to add those new files without having to manual go and add each one? |
| 16:55.45 | CosmicPenguin | no |
| 16:55.46 | CosmicPenguin | I wish there was |
| 16:55.57 | CosmicPenguin | Because I have that problem - I tend to forget to add files |
| 16:56.13 | CosmicPenguin | Like in subversion, I do a subversion status - if its all good, I commit |
| 16:56.18 | CosmicPenguin | forget all about added files |
| 16:56.26 | CosmicPenguin | at least cvs shows unknown files with a ? |
| 16:56.44 | prpplague | CosmicPenguin: i was thinking of writing a script |
| 17:00.26 | prpplague | CosmicPenguin: run patch first on a dry run and see what files are added, then after the patch cvs add them |
| 17:01.14 | CosmicPenguin | heh - I've done that with Perforce before |
| 17:02.06 | prpplague | CosmicPenguin: i don't know why i don't just patch it all and then check it |
| 17:02.13 | prpplague | CosmicPenguin: i mean import |
| 17:02.28 | prpplague | CosmicPenguin: but i like to be able to get the different tags |
| 17:10.15 | kergoth | CosmicPenguin: ? both cvs status and svn status show files that exist locally but not in the repo with a ? |
| 17:10.45 | CosmicPenguin | I'm not getting a ? |
| 17:10.50 | CosmicPenguin | maybe I'm doing it wrong |

| 20:40.23 | prpplague | T0mW: ping |
| 20:41.09 | T0mW | prpplague: plop |
| 20:42.34 | prpplague | T0mW: hey, that compilier issue you had the other day |
| 20:42.40 | prpplague | T0mW: with the -O options |
| 20:42.48 | prpplague | T0mW: refresh my mem about it |
| 20:45.32 | T0mW | prpplague: oh, the -O0 forced an error in my code to appear which remained hidden under -Os |
| 20:46.03 | T0mW | prpplague: it had to do with the stack |
| 20:46.39 | prpplague | interesting |
| 20:46.57 | prpplague | T0mW: -O2 seems to be producing unusable code for my bootloader |
| 20:47.13 | T0mW | prpplague: apparently, -Os inlined the code in such a way as to obscure the stack problem. When I used -O0, it didn't inline the function code and the stack became important (there?). |
| 20:47.33 | prpplague | hmm |
| 20:48.11 | T0mW | -O2 might turn on inline functions whether they are declared to be inline or not |
| 20:48.55 | T0mW | void foo (void) would be a discrete section of code under -O0 but might end up as an inline function with -Os |
| 20:48.57 | prpplague | T0mW: the code works with -O0 but seems slower |
| 20:49.14 | T0mW | -Os seems to have a broad lattitude in what it does with your code |
| 20:49.26 | prpplague | hmm |
| 20:49.34 | prpplague | might try with -Os |
| 20:49.40 | T0mW | prpplague: try selectively using -O0 and -Os with each object file? |
| 20:50.48 | T0mW | prpplague: that is what I did, each Makefile has it's own optimize level to compile the subdir objects: $(CC) $(EXTRAINCS) $(OPTNONE) $(ALL_CFLAGS) -c $< -o $@ |
| 20:51.12 | T0mW | others are: $(CC) $(EXTRAINCS) $(OPTSIZE) $(ALL_CFLAGS) -c $< -o $@ |
| 20:51.40 | prpplague | yea |
| 20:51.41 | T0mW | OPTNONE := -O0 and OPTSIZE := -Os |
| 20:52.00 | T0mW | prpplague: should help you drill down into the problem area |
| 20:52.05 | T0mW | s/area/file/ |
| 20:53.02 | T0mW | mine had to do with an _attribute_((naked)) prototyping that I didn't realize was in the "borrowed" project framework |

| 21:07.16 | T0mW | CosmicPenguin: yeah, just who is going to pay him that dollar? Lineo? LOL |
| 21:07.47 | prpplague | T0mW: hehe, just switched everything over to -Os |
| 21:08.01 | prpplague | T0mW: works great, speed is good, and the code is almost 3k smaller |
| 21:08.10 | T0mW | :-) |
| 21:08.36 | prpplague | 20k |
| 21:08.37 | T0mW | prpplague: yeah, now just you try an debug code optimized with -Os |
| 21:08.45 | T0mW | prpplague: it is weird! |
| 21:09.08 | T0mW | prpplague: esp under ARM |
| 21:09.16 | prpplague | T0mW: yea i added a debug flag in the makefiles |
| 21:09.30 | prpplague | T0mW: debug does -O0 and non does -Os |
| 21:09.44 | T0mW | heh, yeah, works for me |
| 21:10.01 | prpplague | T0mW: now i just have to clean up this autoconf and automake crap thats been bit rotting in cvs |
| 21:10.02 | T0mW | -Os jumping around made my head spin |
| 21:10.08 | T0mW | mm |
| 21:10.23 | prpplague | T0mW: yea i suspect that emsoft used that on their bootloader |
| 21:10.29 | T0mW | I haven't worked with auto{make|conf} |
| 21:10.43 | prpplague | T0mW: i hate it |
| 21:10.50 | prpplague | T0mW: always got problems |
| 21:11.09 | T0mW | don't get me started on autoconf... |
| 21:13.35 | T0mW | I'm wondering on how to handle the ARM exceptions, like data_aborts and such |
| 21:14.34 | T0mW | what I'm thinking of is to store the abort frame into RAM, let the watchdog reset the program, then when the program comes up look to see if a prior abort occured (examine that RAM). |
| 21:14.52 | T0mW | if there was an abort, then write that into the logfile on the MMC |
