2011-12-06 00:16 <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?
2011-12-06 00:31 <Ayla> define "access"
2011-12-06 00:35 <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.
2011-12-06 00:36 <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.
2011-12-06 00:38 <Ayla> you can dump the NAND, but if you don't know the FTL used and the filesystem, it won't be very useful
2011-12-06 00:41 <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.
2011-12-06 00:43 <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.

2011-12-06 00:47 <Ayla> if your device has a µSD, you'd better us that instead
2011-12-06 00:48 <Ayla> and boot a linux kernel
2011-12-06 00:48 <Ayla> from USB
2011-12-06 00:50 <Ayla> I'm gone now, see you
2011-12-06 01:01 <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. :/

2011-12-06 02:02 <kristianpaul> whitequark, wpwrak: food gardens yes it seems
2011-12-06 02:08 <xiangfu> Kuwanger, have you try usbboot?
2011-12-06 02:09 <xiangfu> Kuwanger, jzboot use the firmware that provide by Ingenic. which there is no source code for those firmware.
2011-12-06 02:09 <xiangfu> Kuwanger, but usbboot use the firmware that compiled by us :). and support jz4750 CPU.
2011-12-06 02:10 <Kuwanger> I see.
2011-12-06 02:10 <xiangfu> Kuwanger, it's more like some configure file you needs to edit for fit your device.
2011-12-06 02:10 <xiangfu> Kuwanger, like 'NAND_BUSWIDTH' 'BUSWIDTH' etc. checkout the configure file /etc/xburst-tools/usbboot.cfg
2011-12-06 02:15 <xiangfu> Kuwanger, just check the source code. we remove the jz4750 firmware source code from git. but it should be in git history.
2011-12-06 02:15 <Kuwanger> Okay.  Thanks for the information.
2011-12-06 02:16 <xiangfu> Kuwanger, another thing just FYI.
2011-12-06 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
2011-12-06 02:17 <xiangfu> Kuwanger, they send me two days ago.
2011-12-06 02:17 <xiangfu> Kuwanger, the jz4750 firmware code should be easy make it compile under 'xburst-tools.git'
2011-12-06 02:18 <xiangfu> Kuwanger, in this tar ball it have all xburst cpus(jz4750/60/70) firmware :)
2011-12-06 02:21 <xiangfu> Kuwanger, one thing you need know is the stage1 have to <= 8KB. because the stage1 upload to cpu cache.
2011-12-06 02:21 <Kuwanger> Okay.
2011-12-06 02:43 <whitequark> xiangfu: iirc there is the code for firmware, if you're talking about my jzboot
2011-12-06 02:44 <whitequark> at least I recall quite certainly looking at it and maybe even compiling
2011-12-06 02:44 <whitequark> I may be wrong, through
2011-12-06 02:44 <xiangfu> whitequark, hmm.. didn't find them under jzboot.git.
2011-12-06 02:45 <whitequark> xiangfu: I think it was somewhere in your tree
2011-12-06 02:45 <xiangfu> whitequark, so we are using the same source code. only file name is different?
2011-12-06 02:46 <whitequark> xiangfu: I gues sso
2011-12-06 02:46 <whitequark> almost sure
2011-12-06 02:46 <xiangfu> whitequark, sorry. I thought those files(spl_stage1.bin  spl_stage2_usb.bin) is from Ingenic.
2011-12-06 02:47 <whitequark> they've from something we have based jzboot at
2011-12-06 02:47 <whitequark> that might be ingenic's utility or xburst-tools
2011-12-06 02:47 <whitequark> and the former does not have the code, which I have seen
2011-12-06 02:47 <whitequark> so... I think yes
2011-12-06 02:54 <xiangfu> whitequark, ok. so we advice people using/contribute_to the xburst-stage1/2.bin for now. :D

2011-12-06 06:30 <rjeffries_> sombbody will port Linux on one of these after all it is underneath the Android cruft in any case
