| 15:59.50 | DocScrutinizer51 | wpwrak: or are you talking bout sth else than what's commonly known as ethernet PHY? |
| 16:01.28 | DocScrutinizer51 | ~ping |
| 16:01.28 | infobot | ~pong |
| 16:02.13 | wpwrak | no, it's that PHY |
| 16:02.35 | wpwrak | i don't know if the various coil arrangements are really equivalent |
| 16:02.50 | wpwrak | also, does polarity matter ? |
| 16:03.07 | DocScrutinizer51 | think of it as a number of unrelated baluns |
| 16:04.37 | DocScrutinizer51 | about polarity I'm not sure, but I'd guess it should be taken care of though driver chip will recover from twistedvswapped pairs I think |
| 16:05.40 | DocScrutinizer51 | tbh I never looked into 'modulation' on nBt |
| 16:06.18 | DocScrutinizer51 | you can loo it up in wikipedia for sure |
| 16:09.14 | DocScrutinizer51 | I'd expect a datasheet for ethernet PHY component usually not elaborating on ploarities and coil arrangements, but rather name pins in a defacto standardized way, so you can do the "chinese EE" (connect pins with similar names) |
| 16:10.54 | wpwrak | did you real my mail about the ethernet PHY ? |
| 16:11.13 | wpwrak | the problem is that the thing we have is just not a 1:1 copy of the recommended PHYs |
| 16:13.00 | DocScrutinizer51 | hmm, if you think I should, I might look into it |
| 16:13.18 | wpwrak | that would be great, thanks ! :) |
| 16:13.48 | wpwrak | adam also seems to be mainly based on the assurance of the manufacturer that it's a valid replacement |
| 16:13.49 | DocScrutinizer51 | I could do now if you post the URL to PHY DS |
| 16:14.13 | wpwrak | did you install dsv ? that would give you instant access to all those goodies |

| 16:15.52 | DocScrutinizer51 | my 'real computer' is in maintenance mode |
| 16:19.37 | larsc | dsv = datasheet viewer? |
| 16:21.22 | DocScrutinizer51 | NRZ(I) is basically not polarity aware |
| 16:21.29 | wpwrak | larsc: yup. you give it a list of all the datasheets your project uses with a (set of) name(s) for each. it downloads and caches them. then you look them up with dsv <name> |
| 16:21.48 | larsc | wpwrak: were do i get it? |
| 16:21.49 | wpwrak | DocScrutinizer: excellent. so the winding direction won't matter ? |
| 16:22.03 | DocScrutinizer51 | prolly not much |
| 16:23.28 | wpwrak | good. the chip doens't seem to have anything that lets you swap + and -. although i have to admit that i understand only a fraction of the items discussed there |
| 16:24.58 | DocScrutinizer51 | in 100BT iirc only two pairs of the 4 are used, each for one direction |

| 16:25.44 | DocScrutinizer51 | and if there's only one pair available, some chips do halfdumplex |
| 16:26.15 | DocScrutinizer51 | which then is slow as hell |
| 16:26.17 | wpwrak | maybe it does that, too |
| 16:26.33 | wpwrak | it even has a cable fault analysis function :) |
| 16:28.30 | DocScrutinizer51 | as I see the chip block schem, it has TX and TX' |
| 16:31.19 | DocScrutinizer51 | I don't see a function block to swap TX and RX for that auto thing |
| 16:32.25 | DocScrutinizer51 | so you need a special '0modem' patchcable to connect two identical devices with taht PHY |
| 16:32.52 | DocScrutinizer51 | and I guess that also means it can't do halfduplex |
| 16:36.45 | wpwrak | it has TX/RX swapping |
| 16:36.52 | DocScrutinizer51 | ooh it's no complete PHY as it needs a transformer |

| 21:28.47 | derRichard | can i use a mainline kernel on ben? |
| 21:29.50 | larsc | yes.it will lack some features though |
| 21:30.02 | larsc | mainly usb gadget support |
| 21:30.49 | derRichard | is the gadget driver too ugly for mainline? ;) |
| 21:31.08 | derRichard | does it support dma? AFAIK it was broken when i tried it last time |
| 21:31.32 | larsc | dma works. sg dma not |
| 21:31.52 | viric | sg? |
| 21:32.06 | larsc | scatter gather |
| 21:32.25 | derRichard | larsc: so, using ben as usb disk will not be damn slow? :D |
| 21:32.59 | larsc | ah, you mean the gadget driver |
| 21:33.04 | derRichard | http://projects.qi-hardware.com/index.php/p/ben-nanonote/issues/59/ |
| 21:33.07 | derRichard | this issue i mean |
| 21:33.15 | derRichard | i've reported it some time ago |
| 21:33.16 | larsc | actually i have no idea if dma works for the gadget driver |
| 21:34.10 | derRichard | 1 year 9 months ago it did not work :D |

| 22:34.07 | vano | Hi! Any links showing how to make the debian .uni image to include the remaining 1.5GB (or at least .5GB more) of the NAND? |
| 22:34.13 | vano | *.ubi |
| 22:34.41 | vano | or to make the .ubi image from the debian.tgz? |
| 22:34.58 | viric | vano: it's partitioned so you get 0,5GB of openwrt, 1,5GB of /home |
| 22:35.21 | vano | I know. But I would like it to be 1GB - 2GB of / |
| 22:35.26 | viric | vano: and both debian and openwrt kernels have that partitioning hardcoded. |
| 22:35.35 | vano | ah I see. |
| 22:35.52 | viric | vano: changing one of them, could make users destroy filesystems |
| 22:36.13 | vano | understand… so basically I would have to build my own kernel for this... |
| 22:36.34 | vano | I am trying to install too many things (debian) and run out of space... |
| 22:36.42 | viric | vano: or change its commandline. Many years ago, there was a tool to change the kernel commandline in an image |
| 22:37.02 | viric | I wonder if it still exists |
| 22:37.26 | viric | vano: ah you have debian in the 0,5GB of / ? |
| 22:37.33 | vano | Maybe a better idea would be to move something like /usr/bin to the SD or something like that ? |
| 22:37.40 | vano | yep |
| 22:37.55 | vano | I absolutely cannot get debian boot from the uSD |
| 22:37.59 | viric | :) |
| 22:38.06 | vano | tried everything... |
| 22:38.07 | viric | mkdir /home/usr |
| 22:38.15 | viric | cp -a /usr/* /home/usr |
| 22:38.23 | viric | mount -o bind /home/usr /usr |
| 22:38.32 | vano | hmm |
| 22:38.40 | viric | mount --bind |
| 22:38.41 | viric | sorry. |
| 22:38.41 | vano | true :) |
| 22:38.52 | vano | that should do it…. |
| 22:39.31 | vano | Any ideas as to debian / on the uSD? |
| 22:39.51 | vano | I cannot see the error message… I was going to try with an older boot without the fb screen… but didn't get to find any. |
| 22:40.50 | vano | I have ruled out any fsck issues (or so I think)… cause I can get to boot into NAND with the uSD inserted... |
| 22:41.32 | viric | vano: you have to press a key on boot |
| 22:41.43 | vano | M |
| 22:41.48 | viric | vano: the uboot source has a check, if a key is pressed, it picks the kernel from the uSD, assuming it's in a known filesystem |
| 22:41.56 | viric | and a particular partition. |
| 22:42.16 | vano | which partition? |
| 22:42.22 | viric | http://viric.name/cgi-bin/nanonixos/doc/trunk/doc/boot.wiki |
| 22:42.32 | viric | #define CONFIG_BOOTCOMMANDFROMSD "mmc init; ext2load mmc 0 0x80600000 |
| 22:42.33 | viric | /boot/uImage; bootm" |
| 22:43.35 | vano | that is the correct partition I have… the first partition (and only one in my case) |
| 22:43.49 | vano | the thing it is that, it seems to boot |
| 22:44.03 | vano | but I cannot get to the consoles via ctrl+alt+F2 |
| 22:44.30 | vano | the message logs (that I check later when booting into NAND) don''t show anything wrong either.. |
| 22:44.45 | vano | however of course I cannot get to see the console messages properly. |
| 22:44.49 | viric | do you want to do some kernel debugging? :) |
| 22:44.59 | viric | http://viric.name/cgi-bin/nanonixos/doc/trunk/doc/kerneldbg/index.wiki |
| 22:46.17 | vano | interesting |
| 22:46.46 | viric | you need the serial wire: http://viric.name/cgi-bin/nanonixos/doc/trunk/doc/serial.wiki |
| 22:48.10 | vano | am not a hw guy… but will look at that :) |
| 22:49.21 | vano | btw just in case.. the lat message I get in the console when booting into the uSD is: "ounted. Opts: (null)fs (mmcblk0p1): re-m" .. just in case you could guess what it could be :) |
| 22:49.27 | vano | *last |
| 22:49.54 | viric | only that? it looks like with broken words |
| 22:50.25 | viric | I've no idea on the debian kernel, I never used it. I simply imagine they prepared it right. |
| 22:52.09 | vano | yep |
| 22:52.32 | vano | you are not aware of any problems with the size of the uSD? this is 8GB. |
| 22:52.43 | viric | I used at most 2GiB |
| 22:52.47 | vano | hmmm |
| 22:52.57 | viric | but never booted from sd |
| 22:53.23 | vano | well the uSD seems to work ok mounted when booted into NAND. |
| 22:53.35 | viric | uboot may be more stupid |
| 22:53.38 | viric | than linux |
| 22:53.52 | vano | true |
| 22:54.18 | viric | take a picture of your nanonote screen with debian booted |
| 22:54.41 | viric | anyway I go to bed |
| 22:55.29 | vano | k c ya. |
| 22:58.31 | derRichard | where can i get the sources of xburst-tools? |
