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?
<Ayla>
define "access"
<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.
<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.
<Ayla>
you can dump the NAND, but if you don't know the FTL used and the filesystem, it won't be very useful
<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.
<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.

if your device has a µSD, you'd better us that instead
<Ayla>
and boot a linux kernel
<Ayla>
from USB
<Ayla>
I'm gone now, see you
<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. :/

whitequark, wpwrak: food gardens yes it seems
<xiangfu>
Kuwanger, have you try usbboot?
<xiangfu>
Kuwanger, jzboot use the firmware that provide by Ingenic. which there is no source code for those firmware.
<xiangfu>
Kuwanger, but usbboot use the firmware that compiled by us :). and support jz4750 CPU.
<Kuwanger>
I see.
<xiangfu>
Kuwanger, it's more like some configure file you needs to edit for fit your device.
<xiangfu>
Kuwanger, like 'NAND_BUSWIDTH' 'BUSWIDTH' etc. checkout the configure file /etc/xburst-tools/usbboot.cfg
<xiangfu>
Kuwanger, just check the source code. we remove the jz4750 firmware source code from git. but it should be in git history.
<wolfspraul>
rjeffries: you probably know my thoughts, but just in case :-)
<wolfspraul>
buy one, try it, let us know

my favorite in the article is this line
<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..."
<wolfspraul>
a little mind game
<wolfspraul>
what does this mean?
<wolfspraul>
:-)

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
<rjeffries_>
sombbody will port Linux on one of these after all it is underneath the Android cruft in any case
jekhor joined #qi-hardware
<wolfspraul>
yes. why will the amazon fire for 200 USD a success, but the 100 USD Ingenic tablet a failure?
<wolfspraul>
because one works, and the other one doesn't :-)

it's interesting that there has been no discussion of "carrier iq" here :)

kyak: what's there to discuss ? did you find anything in the least surprising about it ? ;-)
<kyak>
every time something like that is discovered, i'm surprised :)
<wpwrak>
... that it didn't happen before ? :)
<kyak>
that it did happen before, but now it happened again
<kyak>
and probably this is not the last time to happen
<wpwrak>
i think you have about realistic expectations :)

naw, a sleek little samsung dumbphone
<kyak>
in both cases you have nothing to worry about :)
<kyak>
who know though, what misteries are hidden inside of the dumbphone

wolfspraul joined #qi-hardware
<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 :)
<DocScrutinizer51>
wpwrak: btw (lte src) - no access to ds + register specs, so real hacking still futile. Max I could learn about hidden functions
<DocScrutinizer51>
but, as mentioned, real hacking futile anyway due to signing
<wpwrak>
well, real hacking can still translate to knowledge. knowledge is power :)

Hello everyone!
<LunaVorax>
I've just updated my Ben Nanonote
<LunaVorax>
A big thank you for the one who worked on the boot logo
<LunaVorax>
It's perfect
<LunaVorax>
It's clean and good

LunaVorax: gtkperfct and in general gtk apps show ok to you on screen?
<xiangfu>
kristianpaul, there is a problem when quit GTK apps. this bug been there for long time :(
antgreen joined #qi-hardware
<LunaVorax>
kristianpaul, sorry I've been away, you want me to try out theses two softwares?
<LunaVorax>
gtkperf seems to be ok
paroneayea joined #qi-hardware
<LunaVorax>
kristianpaul, if you were talking about gtkperf, it seems to be running mostly ok. A few parts are a bit clunky.
<LunaVorax>
Apart from drawing, nothing shows on screen.
<LunaVorax>
I mean
<LunaVorax>
Drawing is the only test that fails

Hey everyone!
<LunaVorax>
I'm experiencing some troubles with opkg
<LunaVorax>
It tells me it can't download packages with wget but when I does it manually it works ok
