| Kuwanger | I'm not sure if this is the correct place to ask--it seems jzboot is the main open way to access a given Ingenic JZ SoC system, be it an open system or not--but I was wondering if jzboot would actually be useful in trying to access a PMP based on a JZ4750 CPU? Yes or no, is there a place I would best look to find more about the steps in investigating such a device? | 00:16 |
|---|---|---|
| Ayla | define "access" | 00:31 |
| Kuwanger | Well, I was hoping to be able to look through its currently hidden NOR/NAND/ROM space, minimally. Depending on what I find, I was hoping to be able to replace some of it to be able to launch programs from the already accessible NAND space. | 00:35 |
| Kuwanger | I was hoping jzboot would provide be the ability to do the former and what I learn from that coupled with jzboot I could possible do the latter. | 00:36 |
| Ayla | you can dump the NAND, but if you don't know the FTL used and the filesystem, it won't be very useful | 00:38 |
| Kuwanger | Well, I've yet to get as far as dumping the NAND. I tried using the firmware files included with jzboot for stage1 and stage2 files, and the connection always times out. I presume something is actually happening because the second attempt always hangs. | 00:41 |
| Kuwanger | It's more or less that reason which I was wondering if I was just way off in thinking jzboot might be of some use or not. I mean, I recognize getting a NAND dumping may or may not be actually useful. But, it'd seem like a necessary first step. | 00:43 |
| Ayla | if your device has a µSD, you'd better us that instead | 00:47 |
| Ayla | and boot a linux kernel | 00:48 |
| Ayla | from USB | 00:48 |
| Ayla | I'm gone now, see you | 00:50 |
| Kuwanger | Well, the device does have a microSD, but I don't if/how to use it to boot anything. The same is true for booting a linux kernel from USB. :/ | 01:01 |
| wolfspraul | viric: yes I have friends at Ingenic :-) | 01:32 |
| kristianpaul | whitequark, wpwrak: food gardens yes it seems | 02:02 |
| xiangfu | Kuwanger, have you try usbboot? | 02:08 |
| xiangfu | Kuwanger, jzboot use the firmware that provide by Ingenic. which there is no source code for those firmware. | 02:09 |
| xiangfu | Kuwanger, but usbboot use the firmware that compiled by us :). and support jz4750 CPU. | 02:09 |
| Kuwanger | I see. | 02:10 |
| xiangfu | Kuwanger, it's more like some configure file you needs to edit for fit your device. | 02:10 |
| xiangfu | Kuwanger, like 'NAND_BUSWIDTH' 'BUSWIDTH' etc. checkout the configure file /etc/xburst-tools/usbboot.cfg | 02:10 |
| xiangfu | Kuwanger, just check the source code. we remove the jz4750 firmware source code from git. but it should be in git history. | 02:15 |
| Kuwanger | Okay. Thanks for the information. | 02:15 |
| xiangfu | Kuwanger, another thing just FYI. | 02:16 |
| xiangfu | Kuwanger, here is the latest Windows Version usbboot source code from Ingenic: http://downloads.openmobilefree.net/Ingneic/xburst-tools-windows/nand_card_tools.tar.bz2 | 02:16 |
| xiangfu | Kuwanger, they send me two days ago. | 02:17 |
| xiangfu | Kuwanger, the jz4750 firmware code should be easy make it compile under 'xburst-tools.git' | 02:17 |
| xiangfu | Kuwanger, in this tar ball it have all xburst cpus(jz4750/60/70) firmware :) | 02:18 |
| xiangfu | Kuwanger, one thing you need know is the stage1 have to <= 8KB. because the stage1 upload to cpu cache. | 02:21 |
| Kuwanger | Okay. | 02:21 |
| whitequark | xiangfu: iirc there is the code for firmware, if you're talking about my jzboot | 02:43 |
| whitequark | at least I recall quite certainly looking at it and maybe even compiling | 02:44 |
| whitequark | I may be wrong, through | 02:44 |
| xiangfu | whitequark, hmm.. didn't find them under jzboot.git. | 02:44 |
| whitequark | xiangfu: I think it was somewhere in your tree | 02:45 |
| xiangfu | whitequark, so we are using the same source code. only file name is different? | 02:45 |
| whitequark | xiangfu: I gues sso | 02:46 |
| whitequark | almost sure | 02:46 |
| xiangfu | whitequark, sorry. I thought those files(spl_stage1.bin spl_stage2_usb.bin) is from Ingenic. | 02:46 |
| whitequark | they've from something we have based jzboot at | 02:47 |
| whitequark | that might be ingenic's utility or xburst-tools | 02:47 |
| whitequark | and the former does not have the code, which I have seen | 02:47 |
| whitequark | so... I think yes | 02:47 |
| xiangfu | whitequark, ok. so we advice people using/contribute_to the xburst-stage1/2.bin for now. :D | 02:54 |
| Kuwanger | Well, thanks for all the information. I'll try it out and hopefully I'll get somewhere with it. | 03:07 |
| rjeffries | wondering thoughts by people of qi-hardware re $99 Ingenic tablet http://www.linuxfordevices.com/c/a/News/Ainol-Ainovo-Novo7-/ | 05:05 |
| wolfspraul | rjeffries: you probably know my thoughts, but just in case :-) | 05:12 |
| wolfspraul | buy one, try it, let us know | 05:12 |
| wolfspraul | my favorite in the article is this line | 05:29 |
| wolfspraul | "Ingenic's JZ4770 (pictured) is the latest in a line of MIPS-architecture "Xburst" processors, which appeared in early versions of the low-cost Velocity Cruz Android tablets before the company switched to a Cortex-A8 processor in its latest Velocity Micro Cruz..." | 05:29 |
| wolfspraul | a little mind game | 05:29 |
| wolfspraul | what does this mean? | 05:29 |
| wolfspraul | :-) | 05:29 |
| rjeffries_ | wolfspraul that tablet is only available in China. I do not live in china. ;) $99 for a tablet is hard to understand. Amazon Fire 7 in tablet costs them about $210 to build | 06:29 |
| rjeffries_ | sombbody will port Linux on one of these after all it is underneath the Android cruft in any case | 06:30 |
| wolfspraul | yes. why will the amazon fire for 200 USD a success, but the 100 USD Ingenic tablet a failure? | 07:43 |
| wolfspraul | because one works, and the other one doesn't :-) | 07:43 |
| wolfspraul | be a success | 07:44 |

| kyak | it's interesting that there has been no discussion of "carrier iq" here :) | 11:04 |
| DocScrutinizer51 | OSE system programming manual: 2830pp | 11:06 |
| DocScrutinizer51 | *cough* | 11:06 |
| wpwrak | kyak: what's there to discuss ? did you find anything in the least surprising about it ? ;-) | 11:23 |
| kyak | every time something like that is discovered, i'm surprised :) | 11:30 |
| wpwrak | ... that it didn't happen before ? :) | 11:32 |
| kyak | that it did happen before, but now it happened again | 11:33 |
| kyak | and probably this is not the last time to happen | 11:33 |
| wpwrak | i think you have about realistic expectations :) | 11:36 |
| kyak | wpwrak: i assume your phone is something from Openmoko? | 11:37 |
| wpwrak | naw, a sleek little samsung dumbphone | 11:44 |
| kyak | in both cases you have nothing to worry about :) | 11:50 |
| kyak | who know though, what misteries are hidden inside of the dumbphone | 11:50 |
| wpwrak | the good thing about dumbphones is that you don't involve them in a lot of things that wouldn't be plainly visible to the carrier anyway :) | 11:57 |
| DocScrutinizer51 | wpwrak: btw (lte src) - no access to ds + register specs, so real hacking still futile. Max I could learn about hidden functions | 12:17 |
| DocScrutinizer51 | but, as mentioned, real hacking futile anyway due to signing | 12:18 |
| wpwrak | well, real hacking can still translate to knowledge. knowledge is power :) | 12:21 |
| LunaVorax | Hello everyone! | 13:59 |
| LunaVorax | I've just updated my Ben Nanonote | 13:59 |
| LunaVorax | A big thank you for the one who worked on the boot logo | 13:59 |
| LunaVorax | It's perfect | 13:59 |
| LunaVorax | It's clean and good | 14:00 |
| kristianpaul | LunaVorax: gtkperfct and in general gtk apps show ok to you on screen? | 15:05 |
| xiangfu | kristianpaul, there is a problem when quit GTK apps. this bug been there for long time :( | 15:09 |
| LunaVorax | kristianpaul, sorry I've been away, you want me to try out theses two softwares? | 15:13 |
| LunaVorax | gtkperf seems to be ok | 15:15 |
| LunaVorax | kristianpaul, if you were talking about gtkperf, it seems to be running mostly ok. A few parts are a bit clunky. | 15:18 |
| LunaVorax | Apart from drawing, nothing shows on screen. | 15:19 |
| LunaVorax | I mean | 15:19 |
| LunaVorax | Drawing is the only test that fails | 15:19 |
| LunaVorax | Is there a Ctrl+Alt+Del equivalent for the Ben Nanonote ? | 15:21 |
| kristianpaul | i mean characters looks ike squares, bt if you said is know bug, ok.. | 15:49 |
| LunaVorax | Hey everyone! | 21:30 |
| LunaVorax | I'm experiencing some troubles with opkg | 21:30 |
| LunaVorax | It tells me it can't download packages with wget but when I does it manually it works ok | 21:30 |
| kristianpaul | nice http://www.lll.lu/~edward/edward/adsb/VerySimpleADSBreceiver.html | 22:00 |
| kristianpaul | very recursive | 22:00 |
| kristianpaul | now i wonder if is really safe replace current radar tech with this ADS-B | 22:11 |
| kristianpaul | at least if you have the receiver can run in time in case a non wanted colittion :) | 22:12 |
| GNUtoo | LunaVorax, opkg update? | 22:14 |
| LunaVorax | I've done that yes | 22:15 |
| whitequark | DocScrutinizer51: do they do their signing like Motorola does? as in "bootloader like a swiss cheese" | 23:26 |
| DocScrutinizer | I think signing is handled during flashing | 23:27 |
| DocScrutinizer | and probably also during boot, where bootloader hashsums the "kernel" | 23:28 |
| DocScrutinizer | I still have 90% of docs left for reading | 23:28 |
| DocScrutinizer | just about OSE | 23:29 |
| DocScrutinizer | and source is no less than a full bare bones linux system, incl kernel and all - for each chipset | 23:30 |
| DocScrutinizer | millions of sourcelines | 23:30 |
| GNUtoo | DocScrutinizer, what device? | 23:31 |
| DocScrutinizer | STE-chips | 23:31 |
| GNUtoo | ok | 23:31 |
| DocScrutinizer | you might google for thorium, tell me if you get hits | 23:32 |
| DocScrutinizer | http://www.google.de/search?q=thorium+lte+ericsson&ie=UTF-8&oe=UTF-8 | 23:33 |
| GNUtoo | ok I get some hits | 23:34 |
