| 15:34.06 | prpplague | is on the flight to san fran |
| 15:36.49 | prpplague | landley: anything toybox related? |
| 15:43.04 | landley | prpplague: other than poking at merging elie's free and uptime implementations this morning? (And not quite getting through either?) |
| 15:43.10 | landley | Not really. |
| 15:43.28 | prpplague | ahh |
| 15:43.38 | landley | I'm about ~6 hours of work behind on toybox. Finding a spare 6 hours has been tough. |
| 15:43.41 | landley | I have hopes for the weekend. |
| 15:44.21 | landley | I try to merge/review at least one toybox thing each day, just so the ball doesn't stop rolling... |
| 15:44.44 | landley | I did notice a long thread on the busybox mailing list about toybox. I shoudn't be suprrised there was one... |
| 15:44.45 | av500 | landley: you need toy soldiers |
| 15:45.18 | landley | Several of the earlier posts were interesting. Then it sort of spiraled off into "I'm not a coder but" ranting... |
| 15:45.45 | landley | People still seem to have totally missed that toybox is my baby, always was, and that I'm the one doing the work... |
| 15:46.05 | landley | Tim is working on behalf of CELF, not on behalf of Sony, and is _also_ the guy behind the android kernel upstreaming project. |
| 15:46.33 | landley | Put the pieces together guys: he's trying to get the android kernel bits merged and the android userspace cleanly separated. Both of these align with Google's _stated_goals_ for Android. |
| 15:46.46 | landley | Tim == helping Android by Google's own metrics. |
| 15:46.53 | landley | And they blame _SONY_ for this? |
| 15:46.56 | prpplague | landley: only 6 hours? i am behind like two weeks on all my projects |

| 16:06.41 | prpplague | Posterdati: if you are using the linaro toolchain, you need to post on their mailing list, or try the #linaro channel |
| 16:06.54 | Posterdati | ah ok, thanks |
| 16:07.18 | Posterdati | is there any toolchain to use, like codesourcery? |

| 16:09.47 | prpplague | Posterdati: i use codesourcery for a lot of testing |
| 16:10.03 | prpplague | Posterdati: you can also use the toolchains from buildroot or openembedded |

| 16:11.06 | Posterdati | I used to install with their installer and modify the PATH var |
| 16:11.25 | Posterdati | could you help me please? |
| 16:12.38 | Posterdati | I'm reinstalling it right now |
| 16:12.50 | landley | reads backscroll... |
| 16:13.12 | landley | Posterdati: try http://landley.net/aboriginal/bin |
| 16:13.19 | landley | There are cross-compiler variants there for several basic architectures. |
| 16:13.26 | Posterdati | I'm going to install in /home/my-home/CodeSourcery/Sourcery_G++_Lite |
| 16:13.28 | landley | Most likely you want armv5l for arm, mips for mips, powerpc for ppc32. |
| 16:13.37 | Posterdati | ? |
| 16:13.53 | landley | You asked if there was any toolchain. Those are the ones I built and they work for me(tm). |
| 16:14.05 | landley | But the code sourcery ones generally work too, yes. |
| 16:14.11 | Posterdati | ah ok |
| 16:14.47 | Posterdati | prpplague: it is installing |
| 16:15.50 | Posterdati | shall I have to install other libs? |
| 16:16.03 | Posterdati | like libc or libm? |
| 16:18.29 | prpplague | wmat: do you know if the ABS presentations will be online somewhere? |
| 16:18.59 | prpplague | Posterdati: i can not help you in detail currently, i am traveling |
| 16:19.28 | Posterdati | :( |
| 16:19.43 | Posterdati | I installed codesourcery and set the PATH correctly |
| 16:19.52 | Posterdati | then I made make in the project directory |

| 16:21.40 | prpplague | Posterdati: sounds like you have a mismatch between what you are compiling for and what you are linking |
| 16:22.15 | Posterdati | but it is all automated, why emdebian arm-linux-gnueabi- compiled and linked it? |
| 16:22.16 | prpplague | Posterdati: please do not post more than one line of info here, please use pastebin.com or other similar service |

| 16:23.51 | Posterdati | yes |
| 16:23.59 | Posterdati | they are from stellarisware |
| 16:24.31 | Posterdati | Texas Instruments |
| 16:24.39 | prpplague | yea it looks like you have something misconfigured |
| 16:24.58 | prpplague | Posterdati: please contact your TI FAE for support |
| 16:25.32 | Posterdati | this project is correctly compiled in ccs5, then I tried emdebian toolchain, and it compiled it, but example won't work (FaultISR()) |

| 20:00.02 | landley | Posterdati: is cortex-m3 the one that just does thumb 2? |
| 20:00.51 | landley | If I recall stellaris is its' own little tiny embedded OS TI write. Fits in about 16k, runs nommu, pretty much a toy, completely incompatible with Linux? |
| 20:01.02 | landley | s/write/wrote/ and shut up ibot. |
| 20:01.45 | landley | I mostly do Linux. Another guy at work is doing stellaris microcontroller code and I've helped him debug it. |
| 20:03.16 | landley | But I don't have TI's proprietary windows IDE set up, and the stellaris headers/libraries only build in the proprieitary TI environment, they're not compatible with any other compiler I've found. |
| 20:04.15 | landley | (Not that I've tried much. Not very interestd in a proprietary TI microcontroller OS roughly equivalent to about half of 1980's DOS.) |
| 20:08.52 | ohsix | it's the market segment it's in, just slightly above the mps340, and with an oled display on the devkit! |
| 20:30.44 | Posterdati | landley: yes is a thumb processor |
| 20:31.24 | Posterdati | landley: I'm using emdebian toolchain to write, no windows tools nor ccsv |
| 20:31.26 | Posterdati | landley: I'm using emdebian toolchain to write, no windows tools nor ccs |
| 20:35.06 | Posterdati | is ST better? |
| 20:37.09 | Posterdati | landley: ? |
| 20:38.28 | alex4nder | ST is making nice chips these days. |
| 20:39.00 | Posterdati | yes |
| 20:39.02 | Posterdati | I prefer |
| 20:39.12 | Posterdati | alas their docs are badly wrote |
| 20:44.15 | Posterdati | I think they're cheaper than texas |
| 20:57.34 | Posterdati | :( |
| 21:05.12 | landley | Posterdati: to write what? |
| 21:05.37 | Posterdati | ? |
| 21:05.44 | landley | If you're trying to build against stellaris libraries using a toolchain other than the one and only one they ever tested it with: good luck with that. |
| 21:06.17 | Posterdati | landley: there's stellarisware, that is gcc compatible |
| 21:06.42 | landley | Who told you it was gcc compatible? |
| 21:07.20 | Posterdati | landley: there are gcc makefiles in it |
| 21:07.32 | landley | As far as I know, the only people anywhere who have any expertise or interest in supporting stellarisware are the people who sell it. |
| 21:07.47 | landley | It's a proprietary product. Talk to your vendor. |
| 21:08.21 | landley | if you're building a standalone binary against some open source thing (newlib+libgloss for example), we might be able to look through the sources along with you. |
| 21:08.44 | landley | But I haven't got a copy of stellarisware. |
| 21:08.45 | Posterdati | I'm using lwip |
| 21:09.15 | Posterdati | and driverlib for chip peripherals includes |
| 21:09.20 | landley | http://www.sics.se/~adam/lwip/ |
| 21:09.35 | Posterdati | yes |
| 21:09.36 | landley | So you've added a TCP/IP stack to your proprietary OS. That's nice. |
| 21:09.37 | Posterdati | that one |
| 21:09.41 | Posterdati | no |
| 21:10.03 | Posterdati | texas give it for free for gcc development |
| 21:10.14 | landley | Does it come with full source? |
| 21:10.44 | Posterdati | yes |
| 21:10.46 | Posterdati | no bin |
| 21:10.56 | Posterdati | only .h and .c + Makefile |
| 21:11.14 | landley | Huh. |
| 21:11.30 | landley | Ok, we might be able to help you, but note that nobody on here will be any more familiar with stellarisware than you are. |
| 21:11.32 | Posterdati | yes |
| 21:11.38 | landley | So we'd basically just be reading the source code for you. |
| 21:11.46 | Posterdati | I workend on str912 |
| 21:11.50 | Posterdati | I worked on str912 |
| 21:12.05 | Posterdati | and I'm working on stm32 too |
| 21:12.08 | landley | With open source projects, you can find people who work on the project. The developers and people who've done their own short-lived forks and pushed bug fixes upstream. |
| 21:12.22 | Posterdati | landley: yes I know |
| 21:12.32 | Posterdati | I use only open source tools |
| 21:12.42 | landley | But with a project like stellarisware: nobody outside of TI works on it. The people who work on it are all TI employees, therefore the logical thing to do is talk to TI, where every developer familiar with the guts of this project works. |
| 21:13.03 | landley | This is a project which publishes source. It is not developed in by an open source community. |
| 21:13.06 | landley | There's a difference. |
| 21:13.09 | Posterdati | this is a no profit project for a already built piece of hardware :( |
| 21:13.39 | Posterdati | however, lwip is opensource |
| 21:13.49 | landley | It's the difference between the blogosphere and a newspaper. Stuff I write doesn't show up in the newspaper. |
| 21:14.15 | landley | It's pretty much one way, read only. Everything in the newspaper was put there by an employee of the newspaper company. |
| 21:14.15 | Posterdati | :) |
| 21:14.21 | Posterdati | yes |
| 21:14.39 | landley | On things like tumblr and twitter, people republish each other with comments all the time. |
| 21:14.42 | Posterdati | I want to avoid such projects |
| 21:14.43 | landley | Different model. |
| 21:14.50 | Posterdati | closed form projects are dead |
| 21:14.56 | ohsix | it does if you try hard enough, print an insert; go to a newspaper machine, "buy" one, put all your inserts in the rest |
| 21:15.16 | Posterdati | anyway |
| 21:15.25 | Posterdati | landley: my problem is FaultISR() |
| 21:15.27 | ohsix | guerilla promoting! |
| 21:15.42 | landley | The newspaper may publish each edition on its website, but it's read only. I can't respond to it or correct bits of it because I'm not an employee. |
| 21:15.54 | Posterdati | CPU got jammed in it after two or three ethernet ISR callings |
| 21:16.14 | landley | You mean it took a fault and wound up in the ISR? |
| 21:16.22 | landley | Define "jammed". |
| 21:17.12 | Posterdati | simply execution goes in FaultISR() function |
| 21:17.24 | landley | So it's taking a fault. |
| 21:17.27 | Posterdati | I tried to change Clock settings |
| 21:17.31 | landley | Does it say where it's taking the fault from? |
| 21:18.13 | Posterdati | how? |
| 21:18.15 | landley | There should be some variant of a link register containing the address of the faulting instruction. |
| 21:18.19 | Posterdati | I didn't check registers |
| 21:18.26 | landley | You might want to do that. |
| 21:18.35 | Posterdati | I only tested with gdb execution |
| 21:18.50 | Posterdati | I could do that now |
| 21:18.52 | Posterdati | I you |
| 21:18.55 | Posterdati | sorry |
| 21:19.11 | Posterdati | I put a breakpoint in FaultISR() and see what happened |
| 21:21.50 | Posterdati | lol |
| 21:21.59 | Posterdati | it never enter FaultISR() now |
| 21:23.29 | Posterdati | ok |
| 21:23.30 | Posterdati | done |
| 21:23.36 | Posterdati | I'm in FaultISR() now |
| 21:24.47 | Posterdati | how can I check for error? |
| 21:34.38 | Posterdati | ? |
| 21:37.56 | Posterdati | it's an hard fault |
| 21:48.45 | Posterdati | landley: ? |
| 21:48.58 | landley | sorry, busy with dayjob... |
| 21:50.25 | Posterdati | ok |
| 21:57.09 | landley | posterdati: there should be an architecture spec for the cortex-M stuff that says what th einterrupt conventions are. The return address gets stored somewhere, I think in a link register but that's just based on what armv7 was doing. |
| 21:57.25 | landley | Look at the return address, it tells you what instruction caused the fault. |
| 21:57.32 | Posterdati | lr? |
| 22:05.23 | landley | Posterdati: here, maybe this will help: http://balau82.wordpress.com/2010/03/10/u-boot-for-arm-on-qemu/ |
| 22:05.25 | landley | That |
| 22:05.44 | landley | That's part of a series of posts doing a uboot walkthrough on arm, which explains a lot about the arm platform's low-level stuff. |
| 22:05.51 | Posterdati | oh |
| 22:05.52 | Posterdati | thanks |
| 22:40.13 | Posterdati | it's a mess, but ok |
