qi-commitsXiangfu Liu: [xburst] [kernel patch] add fbcon-color-fonts.patch http://qi-hw.com/p/openwrt-xburst/f50daab02:52
hallo99do I need a mips or a mipsel cross compiler for the nanonote?05:34
hallo99I have read somewhere, that mips hardware can switch beetwen little and big endian, so does mips and mipsel work for the nanonote?05:34
mththe kernel and all the libraries are built for mipsel05:44
mthI'm not even sure the CPU can do big endian05:44
mthsome MIPS CPUs can switch, but maybe not this one05:45
wpwrakhmm, so is there no known way to remove the hinge / separate bottom shell and screen, without breaking anything ?06:14
hallo99does gcc generate optimized code for the jz4720, or do I have to use --march=mips1?06:36
wejphallo99, you can use mip32 instead of mips107:14
wejpmips32 even07:14
Ornotermeswejp: have you updated gmu for nanonote to use flac?08:50
wejpthere is no need to update it. Gmu supports flac out of the box, it just needs the right libFLAC. if it is there Gmu can be compiled with flac support and it will work out of the box08:51
wejpas openwrt now seems to come with a more recent libFLAC i guess in the next firmware image Gmu will be included with FLAC enabled08:52
Ornotermeswejp: didn't you see openwrt has updated flac?08:52
Ornotermesoh you did :)08:52
wejpi just said so08:52
wejpmaybe i'll create another binary, but it wouldn't be of any use as soon as there is a new firmware image anyway. not sure if it is worth it08:53
Ornotermesi built it with flac my self but it would be simpler for other if the could just compile it08:54
Ornotermescan't you make have a binary for liblac too?08:55
wejpi could but it should be possible to install libflach through opkg on the nanonote08:58
Ornotermessure, but having it by default in next relase would be good it it can't be dine before09:11
Ornotermesif it*09:12
wejpsure, if the next gmu release is ready before the next official firmware image, i'll add flac support there of course09:22
xdpirateYo, I'm having some trouble getting internet access on jlime on the nanonote, anyone available to help?10:00
xdpirateifconfig usb0
xdpirateecho "1" > /proc/sys/net/ipv4/ip_forward10:00
xdpirateiptables -t nat -A POSTROUTING -j MASQUERADE10:01
iPerlhow can i set time zone in nanonote?10:20
iPerloh, i found the data10:23
wpwraklekernel: in case you can't get an analyzer but have a scope with deep memory, you may be able to use the interactive usb protocol decoder i have in http://svn.openmoko.org/developers/werner/ahrt/host/tmc/10:39
lekernelI don't :(10:41
lekernelor I can use the ml401 to sample the usb signals too...10:41
lekernelor even maybe an avr with v-usb10:42
xdpirateftr my previous issue was solved, i forgot to set the dns server10:42
wpwraklekernel: (use the ml401 itself) that's a nice idea :)10:42
lekernelthe problem with all those approaches is they take far more time than just connecting a proven sniffer10:42
wpwraklekernel: for the kind of work you're doing, you really ought to have a decent scope, though. e.g., the rigol ones have deep memory at quite a reasonable price. that is, if you can live with 100 MHz bandwidth and only 2 channels.10:43
lekerneldecent scope don't have a decent price, so if I can live without them... :)10:44
wpwraklekernel: yup, a good sniffer is better. but if debugging the really low-level stuff, you often end up staring at the scope anyway, because you actually want to see what your signals look like.10:44
lekernelhm, I can probably use a verilog simulator for that10:46
wpwraklekernel: yeah, in the ~1kUSD/EUR segment, rigol is the best you can get. the significantly nicer stuff usually adds a digit to the price tag :-( but yes, i'm lusting after a 500 MHz / 4 chan / 10 MS scope, too :)10:46
lekernelsignals aren't that fast (12Mbps) that weird things happen to them10:46
wpwraklekernel: you can always screw up the analog side :) besides, you need something (host) to talk to your system, don't you ?10:47
lekernelI'm developing the host10:47
lekernelthe analog side is a micrel transceiver with few external components10:48
lekernelhard to screw up10:48
wpwraklekernel: okay, then the device :) or do you already have one you could run in the simulator ?10:48
lekernelplus it probably works already, it correctly detects the pull up resistors of devices10:48
lekernelno, I'd need to develop a model for it too10:48
lekernelthat's why a proven sniffer would make me gain a lot of time10:49
wpwrakthat's a lot of moving parts then10:49
wpwrakwell, if you can't find a sniffer, you may still want to try the scope approach. it worked well for me for writing my little usb stack on the c8051f326.10:50
jebbaanother free hardware project, if you havent seen it:  http://humaneinfo.com/12:37
sid_there is also http://hive-project.de/ most things are in german12:55
sid_its a 3 processor 24 core computer with lan/ps2/vga and so on; OS is self made12:55
kristianpaularhuaco: hey ;)14:08
kristianpaulor i must said hola :)14:08
arhuacoHello kristianpaul :-)14:09
nebajothwhat's upppp16:30
nebajothsudo ifconfig eth0 down16:41
bartbesyou're not in /etc/sudoers16:43
nebajothyour momma is in sudoers16:46
bartbesI know16:47
bartbesepic, right?16:47
bartbesyour momma doesn't even have a username16:48
bartbesoh she's still a '1337' script kiddie?16:49
nebajothj0r m0m, d00d16:49
bartbesoh my mom doesn; t have a user account16:49
bartbesshe just hacks her way in16:49
bartbesI'll stop now, while you still have something to be ashamed of16:52
Ornotermeshttp://blogs.forbes.com/firewall/2010/07/13/millions-of-home-routers-vulnerable-to-web-hack/ good thing nanonote doesen't have a web interface :)16:55
ezdagorAnyone know how to get the ks7010 driver working without it writing, what I suspect to be, debug messages to the current console?21:00
uncloudedezdagor: does the source for ks7010 suggest conditions under which it might suppress those messages?22:31
ezdagorNot that I can tell.22:45
ezdagorHowever there is a debug unit. I wonder if I left it out of the Makefile, if that would make a difference. There aren't too many references to it in the rest of the source code.22:46
ezdagorI'm not too knowledgable in C, though.22:46
ezdagor#ifdef KS_WLAN_DEBUG         int i; #define HEX_OFFSET "\            +0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +A +B +C +D +E +F"         printk(HEX_OFFSET);         for (i=0; i<length; i++) {                 if (i % 16 == 0) printk("\n%04X-%04X:", i, i+15);                 printk(" %02X", *(p+i));         }         printk("\n"); #endif22:50
kristianpaulwolfspraul: how i can get ingenic chips?23:00
kristianpaullike in SAKC23:00
kristianpaulgn8 !23:00
uncloudedazdagor: and you're seeing console output like "+0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +A..."?23:09
ezdagorIt shows a home directory of whoever compiled it, and then a memory address.23:11
ezdagorOver and over again.23:11
ezdagorI removed the debug unit from the Makefile... it didn't compile.23:12
ezdagorI don't claim to know how to compile.23:13
ezdagorEr. Program I mean.23:13

wolfspraulkristianpaul: hmm, which ones do you need, and how many? you mean the qfp 4725?23:30
wolfspraulmaybe Carlos has a few he can send to you? what do you need them for?23:30
kristianpaulwolfspraul: oh wow, not just curios23:31
kristianpaulmay be some day do a small board for custom aplications and fun :)23:31
kristianpaulnothing serious23:31
kristianpauli discover today how to do SMT so ;)23:32
xiangfukristianpaul: I found OpenWrt official package repos update the QT to 4.7.0-beta2.23:33
xiangfukristianpaul: I will test in my pc. see if there is also have compile error.23:34
uncloudedezdagor: sounds like its unrelated to the "+0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +A.." debug then23:34
kristianpaulis second try i did compile23:34
kristianpaulnow i'm buggin you23:34
kristianpaulwell now really off bed23:35
kristianpaulbye all23:35
kristianpaulxiangfu: and i wantted try nanomap, so i dediced update the repo23:36
kristianpauland here we go , error, twice..23:36
