| 00:39.21 | RobNC | g'morning |
| 00:41.38 | RobNC | I have no problem building from the mtn/bb/etc. builds. My problem is in how to modify existing code and force a recompile? It's not as simple as "rm *.o" and re-make image. I've been stumped regarding the proper method and the wikis seem wrong or obsolete (http://www.nslu2-linux.org/wiki/OpenSlug/CustomisingTheBuild ) |
| 00:45.52 | mwester | There are no standard ways to do so; everyone has their own technique. The problem fundamentally is that OE is a tool that assembles distributions, and developing code happens long before the distribution gets assembled. |
| 00:46.12 | mwester | The answer is to use whatever works for you, and to understand WHY it works, and when it will fail you. |
| 00:47.36 | mwester | What, specifically, are you trying to do? Modify source code? Add a patch? change a config? |
| 00:48.58 | RobNC | Hi, mwester. Thanks for your oversight. Indeed, someone had a suggestion for attempt to fix the OOM kernel bug. You probably know about it, when RAM>64MB |
| 00:49.54 | mwester | Ah, kernel development, then. |
| 00:50.02 | RobNC | mwester - I believe I can make my own kernel, but I'd rather do a delta of one of the mainstream distributions to eliminate the differences. I.e., slugosbe without the fix, and slugosbe with the fix. |
| 00:50.42 | mwester | Use the master makefile with the svn repo to build a kernel; no need for OE except as a place to get access to the cross-compiler. |
| 00:51.14 | mwester | That's where all SlugOS kernel work is done and tested, patches are created and committed there, and from there are read in by the OE bulid process |
| 00:52.09 | RobNC | I don't know if I am as skilled as the veterans in being able to use slugimage to extract the kernel, ramdisk, etc. and re-insert a custom one. Perhaps I'm making it more difficult than necessary? |
| 00:53.07 | RobNC | I was only going to use OE to eliminate any deltas between OE-specific issues and kernel. |
| 00:53.10 | mwester | Yes. I personally use kexec to boot the new kernel from somewhere convenient. One can also just flash the kernel alone IIRC. |
| 00:54.25 | mwester | If you insist on use the OE environment, you need to alter the OE process. An overlay or a modified .bb file can do the job, but is best suited if you are adding patches or changing config options. For code tweaking, you need other techniques. |
| 00:54.33 | mwester | They are ugly, but, something like: |
| 00:54.47 | mwester | Build with OE to get a full build with image. |
| 00:54.59 | RobNC | mwester: indeed I think you're right - I've seen that somewhere. I suppose it is possible to re-flash just the kernel, ramfs, and modules, right? |
| 00:55.33 | mwester | In the tmp/stamps directory you will find stamps for each package built, at the "task" granularity -- find the one for the kernel, and delete the "linux-<whatever>.do_compile" stamp. |
| 00:56.14 | mwester | In the tmp/work directory you'll find the kernel source -- edit to suit. Save your work elsewhere because if you screw up, and the "do_fetch" task runs it will overwrite your work. |
| 00:57.06 | mwester | THen when you build again, bitbake will notice the missing "do_compile" step for the kernel, and begin at the compilation stage, and then do all the dependent tasks (including adding modules to the rootfs, and repackaging the jffs2 and kernel intot he .bin file. |
| 00:57.33 | mwester | A real hassle, which is why the kernel master makefile exists, but it does work. |
| 00:58.51 | RobNC | I see, so essentially "tricking" the makefile into re-doing it just for the kernel. I should also remove the .o files right? |
| 01:00.47 | RobNC | Hmm, in regards to the kernel master makefile, would that be interchangeable with the kernel made for, say, slugosbe or le?\ |
| 01:02.38 | RobNC | The reason I ask is that I don't want to assume that a vanilla kernel of a particular version is identical to one built via the OE process. Sometimes there are tweaks, patches, etc. that are branches from the vanilla tree. |

| 01:42.26 | joshin | RobNC: Was it you that was helping ka6sox-laptop figure out why some ram chips weren't working for fattened slugs? |
| 01:43.12 | RobNC | perhaps, if you mean a hardware issue |

| 01:44.40 | joshin | Yup. |
| 01:44.58 | joshin | Were you successful? |
| 01:45.26 | joshin | My development slug was one of those with the problem and I'm hoping for its safe return soon. |
| 01:48.06 | RobNC | joshin: I haven't heard anything about it. |
| 01:48.19 | RobNC | I don't think I have it if that's what you're asking :-( |
| 01:49.18 | joshin | Ok. I'm not sure anymore. Tomorrow will be 5 months since I lent my slug for use as a demo for SCALE |
| 01:49.24 | joshin | Sigh... |
| 01:49.27 | RobNC | Yikes... |
| 01:49.39 | RobNC | prolly sitting on someone's desk |
| 01:50.42 | joshin | I have no idea. I just know that I'll never lend any hardware to an OSS project again without a deposit. |
| 01:51.26 | RobNC | hmm, probably not the project's fault. sorry to hear that. |
| 01:51.55 | joshin | Nope, not the project as a whole. Thanks for the sympathy. :) |
| 01:52.59 | RobNC | So it had some kind of soldering issue or board issue? |
| 01:56.13 | joshin | I don't know. It was a perfectly functioning 32MB RAM slug when I sent it to ka6sox (with a deal being made that he'd upgrade it to 64MB). On the last day of the conference he told me that it developed a hardware problem. 6 weeks or so later he swapped out the PHY and was going to upgrade its RAM. Unforturnately he had some life issues that distracted him from it. The last I heard from him was 2.5 weeks ago saying that "your |
| 01:56.19 | joshin | board is in North Carolina being upgraded" |
| 01:57.00 | joshin | So, since I remembered you upping the RAM in your slug and seeing the "NC" in your nick, figured that you might be the one with my slug. |
| 01:58.41 | CIA-45 | 03bzhou * r8429 10optware/trunk/make/py-tailor.mk: py-tailor: 0.9.31 -> 0.9.34 |
| 01:58.53 | RobNC | Hmm, I can say that the address I gave ka6sox is correct, and I haven't gotten an email or confirmation regarding such. Indeed, I'm from NC as you can probably figure rDNS. |
| 01:59.40 | joshin | So he never sent you a slug? |
| 02:00.28 | RobNC | nope, not unless: 1) it was not sent to my address, 2) it was lost in transit, or 3) it was never sent |
| 02:01.19 | joshin | Ok, thanks for the datapoint. |
| 02:02.37 | RobNC | It's not too hard to add an additional 32MB. I think I asked him if he can remove the battery, buzzer, and caps for easier access to memory. But for me to do that is approx 5 minutes max. |
| 02:04.22 | joshin | It isn't hard if you have experience with SMD soldering or practice with those tiny pins. I can handle thru-hole soldering just fine but all those tiny pins so close together is terribly intimidating. :) |
| 02:04.43 | RobNC | yeah I wouldn't even do it w/o a microscope and SMT tools |
| 02:05.09 | CIA-45 | 03bzhou * r8430 10optware/trunk/ (make/icecast.mk sources/icecast/src-auth_url.c.patch): icecast: 2.3.1 -> 2.3.2 |
| 02:07.33 | joshin | Both of which are on my "Yay I just won the lottery" toy list. :) |
| 02:07.36 | RobNC | I'd guess it probably takes 1-2 hours, depending on if I get interrupted. :-) |
| 02:08.01 | RobNC | heh yeah along with a room you can exhaust the fumes! |
| 02:08.34 | joshin | I have that already. My den/hamshack/project room has good ventilation |
| 02:08.47 | RobNC | If you need to get hold of me, I think you can find my email in the nslu2-linux group posts. |
| 02:08.57 | joshin | Ok, thanks. |
| 02:10.14 | RobNC | no problem, let me know if you don't hear from ka6sox - you've emailed him? |
| 02:11.27 | RobNC | per my records I emailed him my work address May 4th. |
| 02:11.31 | joshin | Yup. I might have to start daily calls to his cell phone. Then hourly ones... :) |
| 02:12.11 | RobNC | heh hope it doesn't come to that... |
| 02:12.55 | joshin | Me too. My wife is rather amazed at my patience. |
| 02:13.11 | joshin | I fear she will use it against me soon. :D |
| 02:13.26 | RobNC | heh talk about lose/lose scenario |
| 02:14.24 | joshin | Scary |
| 02:14.54 | RobNC | yep, I hear ya man... |
| 02:15.29 | RobNC | If you want I can email him and ask if he's sent it out |
| 02:15.43 | joshin | Thanks, I'd appreciate it. |
| 02:16.33 | RobNC | He may be trying to have a bunch done; he asked me for a total of about 10 I think. I'll have to do it in my spare time of course but I can't do them if I don't have them :-) |
| 02:17.34 | joshin | Odds are that mine is in that group. |
| 02:18.05 | RobNC | could it be some other hardware problem? |
| 02:18.25 | joshin | Not that he's told me. |
| 02:18.49 | joshin | No, I think he just told me something to get me off his case for a while and that he hasn't followed up on what he was supposed to do. |
| 02:18.54 | joshin | is being charitable |
| 02:19.16 | joshin | (Only because he hasn't talked to rwhitby yet) |
| 02:20.07 | RobNC | that's good then... |
| 02:20.43 | RobNC | I mean wouldn't it be an awkward situation - give someone a bad board and it becomes worse |
| 02:22.03 | joshin | Last I heard, it worked. I'm just ticked (*charitable*) about the poor communication. |
| 02:23.06 | RobNC | understandable, I mean 1 month is more than enough time you'd think |
| 02:23.37 | joshin | Yup. Well, thanks for your help. Don't want to keep you up too late. |
| 02:23.44 | joshin | <- Phoenix AZ |
| 02:26.53 | RobNC | oh yeah true I'm EST guy. If I get it and have it and the delay is in my court I'll tell you. Heck, if I know which one it is I can have it sent back to you directly if you want. |
| 02:27.28 | joshin | Thanks. Then I can get back to my Gentoo Slug hacking. |
| 02:28.11 | RobNC | has to reinstall OS on laptop - yuck - since SP3 messed up something with registry or MBR - either way not recoverable. Thank goodness for backups but yuck I didn't have Ghost installed. |
| 02:28.12 | joshin | And yes, I use distcc to get my bigger machines do the compiling |
| 02:28.54 | joshin | Ugh. I have a virtual machine with Windows Home server for backups/restores of my wife and kid's Windows machines. |
| 02:29.07 | joshin | It isn't bad for that. |
| 02:29.39 | RobNC | Great! I was just talking with mwester about that - compiling - need to try if the suggested fix works for >64MB detected via APEX/kernel. |
| 02:33.09 | RobNC | ok, good luck joshin and keep in touch if I have your board. |
