| 11:24.03 | LaF0rge | hi koen, stefan |
| 11:34.25 | stefan_schmidt | LaF0rge: Your business project makes project makes progress, so you can eat again? ;) |
| 12:01.21 | LaF0rge | yes, just bought tons of food at the super market ;) |
| 12:13.47 | stefan_schmidt | that's good |
| 12:27.03 | [g2] | OT: koen|work, mickey|lunch LaF0rge I was going to build the OpenPCD firmware, but I'm looking at toolchains now. The wiki says you guys are using gnu-arm |
| 12:27.46 | [g2] | is there an arm-elf tool chain lying around in OE ? |
| 12:29.18 | LaF0rge | g2: www.gnuarm.org |
| 12:29.27 | LaF0rge | g2: you want a toolchain that uses newlib, not glibc or uclibc. |
| 12:29.48 | LaF0rge | g2: why would you build the firmware if you don't have a reader? ;) |
| 12:30.01 | [g2] | LaF0rge I'm on the web site now, but the directions are a little lacking (version etc...) |
| 12:30.13 | LaF0rge | I was using 4.0.2 |
| 12:30.21 | [g2] | LaF0rge I posted to the ML and e-mailed you that I may be building devices |
| 12:30.28 | LaF0rge | http://www.gnuarm.org/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 |
| 12:30.33 | LaF0rge | oh, that's you ;) |
| 12:30.39 | [g2] | nod. :) |
| 12:30.57 | [g2] | I saw you guys rev'd to 0.4 |
| 12:31.11 | [g2] | I'm also going to be building a SAM7 device for GPS logging |
| 12:31.35 | [g2] | so lots of the infrastructure will be similar |
| 12:32.13 | LaF0rge | g2: ok. I'll let you know once the DFU is 100% working (in the next days) |
| 12:32.53 | LaF0rge | maybe you could look into separaring the dfu into a separate project called 'sam7dfu' then. with makefiles, linkerscripts, etc. so it's easy to add with openpcd, openpicc, your project, ... |
| 12:33.28 | [g2] | right. partitioning might be nice |
| 12:33.50 | [g2] | it'll take a little time to get the feel of the little SAM hw |
| 12:33.53 | LaF0rge | I've actually implemented that |
| 12:34.07 | [g2] | you do a lot of sensible things :) |
| 12:34.30 | LaF0rge | the main difficulty is, that there needs to be some shared state/data between DFU loader and 'application firmware' code. |
| 12:35.02 | LaF0rge | it's inheren to the DFU spec... maybe this complication is one of the reasons why nobody really seems to support usb dfu... |
| 12:36.17 | [g2] | but that's why building devies is good, one can learn :) |
| 12:36.59 | [g2] | this embedded stuff is quite addictive, but probably cheaper than cocaine |
| 12:37.13 | [g2] | then again maybe not :) |

| 13:04.07 | LaF0rge | g2: well, until about a week ago, I didn't actually use any ia32 machines, only ppc32/ppc664/sparc64 and x86_64 |

| 13:04.42 | LaF0rge | g2: I guess crosstool can build you a cross toolchain for newlib/arm |
| 13:05.03 | [g2] | nod. there are several alternatives. |
| 13:05.29 | [g2] | I just would have thought x86-32 would make a lot more sense |
| 13:05.38 | [g2] | for the gnuarm guys that is |
| 13:05.45 | LaF0rge | yes, that's true ;) |
| 13:06.01 | [g2] | I mean just configuring the kernel is probably more cpu cycles than building whole systems |
| 13:06.16 | *** join/#openezx jonwil (n=jonwil@60-240-174-129.tpgi.com.au) |
| 13:06.33 | [g2] | NF modules are probably 5x the full openpcd build :) |
| 13:07.52 | LaF0rge | g2: but then, at netconf we already mused about ia32 being completely dead, and wondering when the kernel code would bitrot for it ;) |
| 13:08.12 | [g2] | heh |
| 13:36.14 | jonwil | hi |
| 13:36.20 | jonwil | IA32 isnt dead |
| 13:43.33 | LaF0rge | jonwil: well, apart from mobile processors, which don't support the 64bit extensions? |
| 13:43.53 | LaF0rge | yes, geode and via, and others with almost insignificant market share |
| 13:44.34 | jonwil | while it is true that pretty much all new current x86 chips support x86-64, there are 2 things that will keep ia32 alive |
| 13:44.45 | jonwil | firstly, is all the existing ia32 chips out there in real world use |
| 13:45.03 | jonwil | like my 3.4 GHz P4 which doesnt do x86-64 |
| 13:45.15 | SuN | And consequently, is obsolete! |
| 13:45.23 | jonwil | It does what I want |
| 13:45.30 | jonwil | I dont need x86-64 |
| 13:45.35 | SuN | Insignficant! |
| 13:47.16 | jonwil | as long as there are people running linux on ia32, there will be people maintaining linux on ia32 |
| 13:47.33 | SuN | Yeah, so it'll be around for another year or so. |
| 13:47.44 | LaF0rge | jonwil: yes, but I'm talking about current kernel develpoemnt. and I've never seen it driven by 'old, existingly deployed cpus' |
| 13:48.58 | jonwil | on linux x86-64 is going places |
| 13:49.05 | jonwil | but in the windows world its going nowhere |
| 13:49.43 | SuN | The Windows world in general is going nowhere, nothing new there :) |
| 13:50.09 | jonwil | now if only someone would port MingW to x86-64... :) |
