#qi-hardware IRC log for Wednesday, 2010-10-13

cfyxiangfu: i reflash debian,when i boot it00:33
cfyxiangfu: it stop at one step00:34
cfyxiangfu: why the log on the taobao is missing?00:37
cfyxiangfu: i have seen i have sell none?00:38
xiangfucfy: what you mean "one step". OpenWrt screen come out?00:40
cfyxiangfu: no,the debian00:40
cfyxiangfu: i have reflash the uboot00:40
xiangfucfy: hmm.. I can find out the the log inside the taobao account.00:40
cfyxiangfu: i guess the reset is the software button?00:40
xiangfucfy: what you want do about taobao log?00:40
cfyxiangfu: yesterday someone ask me where to buy it00:41
xiangfucfy: the "reset" hole (at the back of nanonote) is hardware.00:41
cfyxiangfu: i find your shop,but i found nothing about the sell log00:41
cfyxiangfu: i stop at:  Algorithmics/MIPS FPU Emulator v1.500:41
cfyxiangfu: s/i/it/00:42
cfyxiangfu: oh?i know00:43
cfyxiangfu: do you know this step mean?00:43
xiangfucfy: hmm.. don't why Taobao delete the log. too bad.00:44
cfyxiangfu: yes,so someone may not trust you.00:45
xiangfucfy: which kernel and Debian rootfs you use?00:50
cfyxiangfu: http://pyneo.org/howto/debian/nano.html00:51
xiangfucfy: checkout this: http://dating.taobao.com/q/6155834.htm?lo=9&w=%B3%C9%BD%BB%BC%C7%C2%BC+%C3%BB%D3%D0%C1%CB this is why there is no "sell log" anymore.00:52
cfyxiangfu: oh,that's bad00:52
xiangfucfy: have you run "usbboot -c "nerase 0 4096 0 0""  are you sure you have follow those steps: http://pyneo.org/howto/debian/nano.html00:58
cfyxiangfu: i follow this00:59
cfyusbboot -c "boot"00:59
cfyusbboot -c "nprog 0 openwrt-xburst-u-boot.bin 0 0 -n"00:59
cfyusbboot -c "nprog 1024 openwrt-xburst-qi_lb60-uImage.bin 0 0 -n"00:59
cfyusbboot -c "nprog 2048 debian-lenny.ubi 0 0 -n"00:59
cfybut the uboot is bad,so i flash the uboot00:59
cfyxiangfu: i try it agian00:59
xiangfucfy: you better erase the rootfs. before you reflash the rootfs.01:00
cfyxiangfu: oh,got it01:00
cfyxiangfu: you mean the 'reset' is the hardware?but booting is stop.but  now i press it but not work01:06
cfyrestart my emacs01:07
cfyxiangfu: êý­5�†01:09
xiangfucfy: I can sure the "RESET" hole is hardware reset. whenever you press the "RESET" , it's will reset the CPU.01:09

wpwrakkristianpaul: (non-commercial) that's just childish. "i'm not making any money with it, so nobody else should". they'll be sorry ever after when they grow up and realize that they've just prevented themselves from using the projects they contributed to.02:03
wpwrakkristianpaul: (N pF) you'll need more driver strength. e.g., an oscilloscope will add ~10-20 pF too.02:05
wpwrakkristianpaul: i'd recommend to make i as strong as you can. this may cause noise that distorts the RF reception, but you can probably worry about that later.02:06
wpwrakkristianpaul: i.e., if you have otherwise good reception, even a noisy RF circuit will pick up enough of a signal that you can do something useful with it. once that part is done, it should be relatively easy to adjust drive strength.02:33
wolfspraulwpwrak: nothing with non-commercial or no-derivative clauses can become part of qi02:34
wolfspraulI'm not sure whether it's written up somewhere or not, but we all agree on that, long time ago already02:34
wpwrakkristianpaul: (one way would of course be to just watch the digital signal with a decent scope. since the probe adds a significant capacitative load, the signal will be better after removing the probe)02:34
wolfspraulgotta run02:34
wpwrakwolfspraul: (nc/nd) makes sense02:35
qi-bot[commit] Werner Almesberger: schhist/gitsch2ps: removed redundant quotes in assignments. http://qi-hw.com/p/eda-tools/a1d118203:50
wpwrakxiangfu: (getting fped ready for debian) nice work, thanks !04:57
Action: xiangfu and Wolfgang in Ingenic Office now. :)04:58
xiangfuwpwrak: still working on that. hope I can fix the last problem today. running Depends .04:59
wpwrakxiangfu: ah yes, the list of dependencies is quite long :)05:00
xiangfuwpwrak: there are steps in debian.org how to find out the dependencies. I will work on that later. then let you know.05:01
cfyxiangfu: i still can't boot the debian05:03
cfyxiangfu: either from the nn,or the sd card05:03
cfyxiangfu: whats wrong with your blog?i can visit it05:05
qwebirc97155from where i can tap 3.3V from Nanonote ?05:25
qwebirc97155anybody here who can tell me the TP to get 3.3V05:32
cfyxiangfu: boot debian from sd card,i wait about 30s05:47
cfyxiangfu: but boot from the nn(debian),i wait more than 30s,but still stop at one step05:48
cfyi failed flash the debian or just booting debian on nand is just slow05:49
cfyxiangfu: ssh root@
cfyRead from socket failed: Connection reset by peer05:53
cfyi can't ssh to nn05:54
cfythe default nameserver  of debian on nn seems don't work in china06:18
cfyi use
Action: kristianpaul curios about xiangfu and Wolfgang meeting in Ingenic06:47
kristianpaulwpwrak: yeah i was reading about probe load and signal will be better indeed (when not seeing it from it), i hope found in the lab good quality probes  too :)06:48
kristianpaulmethril_work: hey :)06:58
methril_workkristianpaul, hey!!07:01
methril_workhow are you? I see you resolved the OpenOCD problems07:02
wpwrakqwebirc97155: you could use the micro-SD slot or get it directly from the pcb.07:35
wpwrakqwebirc97155: http://www.almesberger.net/misc/ben/idbg-v2-install.jpg07:35
wpwrakqwebirc97155: TP9, right next to the black GND line in the picture above07:35
Action: FrankBlues waves09:33
kristianpaulmethril: some of then , actually now i need ad support to the CPLD09:50
qi-bot[commit] carlos: lm32 loader http://qi-hw.com/p/nn-usb-fpga/7b666c009:50
kristianpaulWhat's the best way of creating files using Lib C/ANSI C?10:35
kristianpauli guess stdio10:35
wpwrakfile = fopen("name", "w");10:37
wpwrakwell, do you just want to create it or also write to it ?10:37
kristianpaulif no exist create then write10:38
kristianpaulbtw reading unix design principles it said that avoid uses binary formats10:39
wpwrakthat's a good practice, yes10:40
wpwrak(create+write) fopen is what you want10:41
kristianpauli ok10:41
kristianpaulthe sd-like memory will put me away from IO bottleneck13:33
kristianpaulwoo this projetc is really moving on documentation http://www.gps-sdr.com/wiki/gps-sdr/Acquisition13:41
kristianpaulThis channel is getting so quite as some moths ago :/13:42
kristianpaulwhy the universe behave like a Wave in some aspects.. !13:43
wpwrakhmm, quiet ? :)14:23
wpwrakdid you somehow miss the jlime/patent discussions ? :)14:23
kyak!seen uncloaded14:27
kristianpaulwpwrak: i try to ignore pantents discussion, remenber qi is free of patents :-)14:35
kristianpaulwpwrak: what is this #define    REG(n)    (*(volatile uint32_t *) (mem+(n)-GPIO_BASE)) ?14:41
kristianpaulwhy you stope usign the memory allocation fuction on  blinkenlight example?14:43
wpwrakthat's an access to a register. mem is the pointer to the area where the GPIO registers were mapped into the process' address space. n is the register address, GPIO_BASE is the offset of the GPIO registers.14:46
wpwrakthe cast turns this into an unsigned 32 bit integer. the volatile means that the compiler is not allowed to reorder writes, or to cache data14:47
wpwrak(mem alloc) erm, what do you mean ?14:47
wpwrakwhere do you think there should be a malloc ?14:48
kristianpauli dont14:48
kristianpaulyou already got the pointer..14:48
wpwrakmmap allocates the address space. i don't need to malloc it.14:49
wpwrak(it's also address space where the memory doesn't come from the space malloc uses)14:49
wpwraki.e., the underlying memory in this case are some of the memory-mapped SoC registers14:49
kristianpaulahh yes sure i was confused14:49
kristianpaulyeah malloc is for when i want let said 12 ints like a pointer14:51
kristianpaulsory i tend to swap names :/14:53
Greek_o_nikosDo I have to be a developer to use the Ben Nanonote?15:25
Greek_o_nikosI don't expect anything from the device other than transferring text files to it and reading them.15:30
bartbeswell, why would you have to be a developer?15:31
Greek_o_nikosbartbes: ok, that explains it. Thanks for answering my question.15:32
qbjectWow. I'm surprised ever time I get the qwebirc captcha right.15:43
kristianpaulGreek_o_nikos: you dont, actually if you are no way related with development, your comments about the nanontoe are very helpfull15:55
qi-bot[commit] Ayla: The selector filters will now match also the files with an extension in uppercase. http://qi-hw.com/p/gmenu2x/5cd92b716:18
qi-bot[commit] Ayla: When adding a new link, the default brightness is now -1. http://qi-hw.com/p/gmenu2x/69c702f16:18
qi-bot[commit] Neil Stockbridge: There is now a tool for creating un-fuzzy fonts http://qi-hw.com/p/setfont2/ecd17dc17:35
qi-bot[commit] Neil Stockbridge: There are now two example Pre fonts http://qi-hw.com/p/setfont2/267d16617:41
qbjectdjbclark: do you have any plans to sell replacement batteries for BNN?18:36
kristianpaulMOstly OT^21:33
kristianpaulhmm may be video part can give clues for his repdrocution in the nanonote using free-of-patent software21:46
kristianpaul4:2:0 !21:54
