| TheOnlyJoey|desk | Ohai, question, does anyone has a working debian-weezy image for easy debian boot? i tried updating a squeeze image for 1 whole day, the n900 crashed and rebooted and i could not save it anymore, would save me a lot of time | 00:37 |
|---|---|---|
| TheOnlyJoey|desk | the version hosted by Qole is armhf zo can't use that | 00:37 |
| ShadowJK | Might work with kernel-power? | 00:39 |
| TheOnlyJoey|desk | kernel power? | 00:39 |
| ShadowJK | The enhanced kernel | 00:39 |
| ShadowJK | for power users | 00:39 |
| ShadowJK | It has errata workarounds to make hf mostly work | 00:39 |
| ShadowJK | armhf* | 00:39 |
| TheOnlyJoey|desk | ah cool | 00:40 |
| ShadowJK | Though I guess that's a maemo thing and not a debian thing? | 00:40 |
| ShadowJK | For some reaosn I read your "boot" as "chroot" :) | 00:40 |
| ShadowJK | reason* | 00:40 |
| TheOnlyJoey|desk | well, i ment chroot actually | 00:40 |
| TheOnlyJoey|desk | so i think i will first install kernel-power then, any disadvantages? | 00:41 |
| ShadowJK | As always, make backups first? | 00:43 |
| ShadowJK | It replaced the original kernel. It can not be installed (but you can install the nokia kernel again if you want) | 00:43 |
| TheOnlyJoey|desk | of course, but any known regressions with kernel-power? | 00:44 |
| ShadowJK | mm Not that I know of | 00:44 |
| freemangordon | ShadowJK: hmm, I think you mixed thumb2 with hardfp :) | 00:44 |
| ShadowJK | lol oops | 00:44 |
| ShadowJK | Nevermind me then :) | 00:44 |
| TheOnlyJoey|desk | hmm? | 00:44 |
| ShadowJK | freemangordon, please correct my ramblings :D | 00:45 |
| freemangordon | hardfp should "just work", afaik it is not related to the kernel | 00:45 |
| ShadowJK | As for crashing, stock N900 config is prone to doing that during heavy I/O. I do "echo 1024 > /sys/block/mmcblk0/queue/nr_requests" after boot, also for mmcblk1 if I have microsd. Seems to make the situation much better | 00:46 |
| freemangordon | but if that "hardfp" image is also thumb2 compiled, kernel-power is a must | 00:46 |
| freemangordon | TheOnlyJoey|desk: which kernel do you boot with that image? | 00:47 |
| ShadowJK | If you're going to be doing alot of I/O or RAM heavy stuff, I would definitely recommend getting a fast memory card, Samsung MicroSDHC Pro is known to be fast, and put your chroot fs and swap on there. | 00:47 |
| kerio | well | 00:47 |
| kerio | "fast" as in throughput or as in IOPS? | 00:47 |
| TheOnlyJoey|desk | 2.6.28-omap1 | 00:48 |
| freemangordon | kerio: both | 00:48 |
| ShadowJK | IOPS | 00:48 |
| ShadowJK | I don't really remember or look at throughput | 00:48 |
| TheOnlyJoey|desk | freemangordon, when i boot that image, i get errors about arch mismatch and such, so i think i need a different kernel to do that | 00:49 |
| freemangordon | TheOnlyJoey|desk: hmm, are you sure you boot it with the correct kernel? also, iirc qole's image is for chroot, not for booting | 00:49 |
| TheOnlyJoey|desk | freemangordon, i ment chroot | 00:49 |
| freemangordon | or this is another "image" I am not aware of | 00:49 |
| TheOnlyJoey|desk | i am trying to boot debian_wheezy3sulu_armhf.img which is the latest wheezy | 00:50 |
| freemangordon | then you'd better ask sulu how to do it, there is a thread on TMO | 00:50 |
| TheOnlyJoey|desk | well as long as my kernel supports armhf it should work | 00:53 |
| TheOnlyJoey|desk | so i think i just need another kernel | 00:53 |
| freemangordon | TheOnlyJoey|desk: hardfp is not a kernel thing afaik, it is how the FP arguments are passed when you call a function - it is either via integer registers (softfp) or FP registers (hardfp) | 00:55 |
| *** florian has quit IRC | 00:55 | |
| freemangordon | anyway, you may want to install kernel-power and test with it, though I doubt it will help | 00:55 |
| TheOnlyJoey|desk | well if kernel-power is beter anyway, no harm in doing that as well | 00:56 |
| freemangordon | sure | 00:56 |
| TheOnlyJoey|desk | now running kernel52 :) | 01:03 |
| *** dhbiker_ has quit IRC | 01:03 | |
| arcean | freemangordon: iirc from harmattan times you can't run hardfp software on softfp system | 01:04 |

| ShadowJK | Seriously, the emmc is so "slow", anything beyond storing mp3s and movies, you want to get a fast microsd, like the Samsung Pro MicroSDHC | 01:29 |
| *** Guest68774 is now known as FIQ | 01:29 | |

| Ras_Older | Hey everyone! Sometime earlier this week I was asking for help with my N900's GPS lock problem. I have been running the Location Test app in different places (outdoors mostly) and witnessed that the carrier to noise density ratio for satellites is _always_ at 6 dBHz. However the satellites list does update all the time so it does see / hear them but no lock whatsoever. | 19:42 |
| Humpelstilzchen | Ras_Older: did you try to disable a-gps? | 19:45 |
| *** protem has quit IRC | 19:45 | |
| Ras_Older | The time and date is correct too. I have tried enabling mobile connection to boost the signal as someone told me to try it out but no cigar here so far.. Is there anything left to try or should I just give up? No there is no practical reason for me to get it working but I just wanted to dwell into this to learn about it. Yes the AGPS is disabled atm. When its enabled I get rough +300m radius location its almost everytime the local cell tower. | 19:46 |
| *** lardman has joined #maemo | 19:53 | |
| sixwheeledbeast | spoofy: I use the GTK version on N900 | 19:56 |
| sixwheeledbeast | Ras_Older: well with AGPS on you should get a "course accuracy" GPS and then after about a minute outside you should get "fine accuracy" GPS. | 19:58 |
| sixwheeledbeast | whereas with AGPS off you can hang about for upto 30 minutes or more waiting for GPS to lock. | 19:59 |
| sixwheeledbeast | Normally in the van it takes about 8-9 minutes to lock with A-GPS off. | 20:00 |
| Humpelstilzchen | sixwheeledbeast: where did you get that number from? | 20:00 |
| sixwheeledbeast | experience | 20:00 |
| Ras_Older | Well currently two hours outside without AGPS. I am monitoring the signal level over VNC and they have stayed at 6 dBHz. | 20:00 |
| Humpelstilzchen | sixwheeledbeast: you "only" need 13 minutes | 20:01 |
| Humpelstilzchen | with plain gps | 20:01 |
| spoofy | sixwheeledbeast: qml version seems to be nice and fast. | 20:04 |
| spoofy | but it's not loading maps | 20:04 |
| spoofy | dunno why | 20:04 |
| sixwheeledbeast | well that's not what I have found, out in the field. It happens occasionally where I get no lock for a least 30 minutes. | 20:05 |
| sixwheeledbeast | spoofy: any output if run from terminal? | 20:05 |
| *** _rd has joined #maemo | 20:06 | |
| Humpelstilzchen | sixwheeledbeast: antenna problem? | 20:06 |

| sixwheeledbeast | Humpelstilzchen: possibly, it has never been a big enough issue for me to investigate. Woul | 20:07 |
| sixwheeledbeast | Would anything else cause that? | 20:08 |
| Humpelstilzchen | well to get a fix without any prior data you need information from the satellites that is periodically send over about 13 minutes, if some bits are missing you need to wait longer | 20:09 |
| sixwheeledbeast | maybe this is the case then. | 20:12 |
| *** pdz- has quit IRC | 20:13 | |
| Humpelstilzchen | btw don't hold the n900 in your hand if you need to get a fix ;) | 20:13 |
| honestly | yep, n900 gps chip is old and doesn't have good algorithms for getting initial fix | 20:14 |
| honestly | so it takes a while | 20:14 |
| honestly | my old navigation thingy is the same | 20:15 |
| *** pdz has joined #maemo | 20:16 | |
| *** arcean has quit IRC | 20:16 | |
| Ras_Older | I now enabled the AGPS with supl.nokia.com since the supl.google.com never seems to get a fix for me. I have the certman updated too. The N900 now got a cell tower location again but nothing on the GPS side as the signal levels are still non existent basically. | 20:16 |
| *** e2718 has quit IRC | 20:20 | |
| *** _rd has quit IRC | 20:21 | |
| sixwheeledbeast | Ras_Older: well maybe it is a aerial issue like mentioned above. | 20:21 |
| sixwheeledbeast | Ras_Older: this is the aerial part http://www.klc.fi/fin/images/264805.gif | 20:23 |
| Ras_Older | Ah yes. Going to keep it running for an another hour just to be sure and then call it quits. So guys how is the Neo900 going? Starting to feel like getting a new toy soon :) | 20:25 |
| honestly | it's going well, go donate ;-) | 20:29 |
| Ras_Older | I'll do just that the first thing I get my own finances sorted out :'D | 20:31 |
| honestly | yeah, having that problem too... | 20:32 |

| DocScrutinizer05 | Humpelstilzchen: 2*13min = 26min ~=30min. sounds absolutely correct. with much bad luck two dropouts after 12 and 24 minutes garble same databits of almanac, and you will need a third 13min round to get a complete dataset without dropouts | 20:55 |
| *** useretail has quit IRC | 20:57 | |
| sixwheeledbeast | do you need the full almanac data in one go, or can it piece it together? | 21:04 |

| DocScrutinizer05 | thus I said "with bad luck you have two dropouts in two turns on *the same* data bits..." | 21:09 |

| sixwheeledbeast | ah, a see. sorry I read that differently | 21:15 |
| DocScrutinizer05 | the dataformat has already some code spreading and forward error correction, so short dropouts shouldn't hurt. However all this can also aonly handly a certain amount of dropouts/noise during i´one 13min dataset | 21:15 |
| DocScrutinizer05 | also only handle* | 21:16 |
| DocScrutinizer05 | there's a really excellent website explaining the technical aspects (really all of them) | 21:20 |

| DocScrutinizer05 | however you don't really need the almanac data to get a fix. You could as well be lucky and find the right encoding and doppler etc by mere try&error (you=chip) | 21:44 |
| DocScrutinizer05 | which *should* be faster than 12min usually, aiui. At least on modern chips with many correlators | 21:45 |

| DocScrutinizer05 | with almanac however you can pick the richt encoding aka SV and doppler etc instantly and thus get a first fix relatively fast (10..20s) - or you have an incorrect almanac or an incorrect time setting or corse location estimation and search the 8 wrong channels for hours without ever finding a signal | 21:47 |

| DocScrutinizer05 | note that every SV sends its own ephemeral data in each set of 5 frames during 30s, so after 30s the chip has enough data to do a fix, after it found 3 sats | 21:50 |
| DocScrutinizer05 | for time it needs max 30s after finding first SV | 21:51 |
| DocScrutinizer05 | though that time "isn't accurate" yet, it still has an offset depending on receiver<->SV distance | 21:52 |
| DocScrutinizer05 | but actually I have no clue how GPS works. Rather ask somebody who does: SpeedEvil | 21:53 |
