<deweydb> hi!
<deweydb> I just found out about picuntu, trying my first flash onto a MK802 IV
<deweydb> very glad to see there is an irc chan :)

<ncrmnt> It does look like I finally got 2048x1536 LCD panel working on RK3188. (Obligatory proofpic: http://rghost.net/50535864/image.png )
<ncrmnt> Although with no proper suspend/resume for the panel.

<ncrmnt> I had to make a bunch of hacks all the way around to make it work. Namely, I don't right now quite understand why lcdc doesn't start when the fb0 is opened. And when I enable the framebuffer console I get a black screen
<ncrmnt> But it works.
<ncrmnt> Do you know if Mali plays nice with VT switching, or it's better to disable fbcon if I plan to use mali?

<avRoogh3> :wq
<avRoogh3> oops
<mnemoc> my irc client doesn't support vi commands yet either :<
<avRoogh3> hehe
<avRoogh3> while I'm here. I have bought the Lenovo a10, with the RK3188. lsusb tells me however the vendor id is 'Bus 002 Device 028: ID 17ef:74f8 Lenovo', not 2207. what's up with that? trying to use rkflashkit etc but none see it.
<avRoogh3> adb does (using 2207 in udev rules), but as i don't know the memory ranges, i'm reluctant to go further.
<ncrmnt> avRoogh3: I guess lenovo did the branding. Try to change the vid in rkflashtool sources and see if it works
<avRoogh3> ok
eebrah has quit [Read error: Connection reset by peer]
<ncrmnt> rkflashtool p should give you the params and mem ranges
tonikasch has joined #linux-rockchip
<avRoogh3> oh, didn't know this.
<avRoogh3> cheers
<avRoogh3> am using 'rkflashkit'. will try rkflashtool
<ncrmnt> never tried that one, since rkflashtool worked for me.

<avRoogh3> ncrmnt: hrmm. changed 2207 to 17ef in all occurrences in the rflashtool source, recompied, changed udev rules, restarted udev, plugged in USB into a10 netbook but no joy.
<avRoogh3> rkflashtool b sees nothing.
<avRoogh3> adb devices does, however.

<avRoogh3> this is the device, by the bay, an Android tablet/netbook: http://www.engadget.com/2013/10/09/lenovo-ideapad-a10-leak/
<avRoogh3> great hardware. really rugged. bought it for EUR210
<ssvb> avRoogh3: I'm considering to buy Lenovo A10 too (once/if it gets confirmed to have non-locked bootloader)
<ncrmnt> You need to reboot to bootloader mode if your want to flash something
eebrah has quit [Read error: Connection reset by peer]
<avRoogh3> ncrmnt: yes, i am trying. have a very sad Android lying on the screen currently.
<ncrmnt> nope, that's recovery.
<ncrmnt> the other key
<ssvb> ncrmnt: are there some simple step by step instructions available somewhere?
<ncrmnt> The one connected to GPIO1 bit 0
<ncrmnt> ssvb: I doubt.
<avRoogh3> ncrmnt: oh. no idea where that is. i'm using ./adb reboot bootloader
<ncrmnt> avRoogh3: Your're doing it wrong.
<avRoogh3> yes, quite likely.
<avRoogh3> i tried power and ESC but that doesn't get me a bootloader either.
<ncrmnt> On my Pipo M6 Max Pro 3g there's a reset button
<avRoogh3> there is one underneath here also, but it just reboots the device. a small hole on the base.
<ncrmnt> Yep. Press this reset button, then one of the other buttons.
<ncrmnt> Try all of tem
<avRoogh3> ok
<ncrmnt> The correct sequence will shouw nothing on the screen, but your device will show up in lsusb
<ncrmnt> Do you have UART console connected?
<avRoogh3> no.
<ncrmnt> Well, if you plan on hacking around the device - I suggest you do that ASAP
<ncrmnt> at least you'll know what's happening to the kernel
eebrah has joined #linux-rockchip
<avRoogh3> ok. i'll research how to do this. thanks.
JochenKauz has joined #linux-rockchip
<ssvb> ncrmnt: ok, then I guess I just need to wait a bit longer :) also I would prefer the 2GB RAM / 32GB EMMC configuration for Lenovo A10 and it does not seem to be available in the shops yet
<ssvb> avRoogh3: are they using a glossy screen?
<ncrmnt> ssvb: I just got mine on aliexpress for about 300 bucks or so. Delivery time to russia sucks ( had to wait 36 days!) but, since local shops usually sell overpriced crap this looks like a deal.
<ncrmnt> Oh, and btw - it's not eMMC
<ncrmnt> Mine has 32GB of NAND
<ssvb> raw NAND?
<ncrmnt> Well, not quite raw. RK3188 has some FTL in their NAND driver. Apparently closed-source
<avRoogh3> mine has 16Gb NAND
<ncrmnt> basically you compile rk_nand_base, then insert proprietary crippled rknand.ko and voila - you have your nand as /dev/mtdblockX
<avRoogh3> and 1Gb RAM. it was an impromptu purchase. will take it back if i can't get it up and running with a Linux* tonight as I have work to do!
<ssvb> ncrmnt: this kinda sucks, hopefully it can be reverse engineered
<ncrmnt> but these mtdblock devices are hacked up in a way you can use ext4/vfat
<ncrmnt> ssvb: Will take some time. Worst part is that bootloader uses the same FTL
<ncrmnt> so getting rid of FTL in kernel and running ubifs may screw up bootloader
<avRoogh3> ncrmnt: do you have yours? if so, what are you running on it?

<ncrmnt> I just got my tablet about 2 weeks ago. While now it's running stock most of the time. I'm now working on bringing up most of the stuff on the homebrew kernel
<ncrmnt> I plan on running debian wheezy & KDE there
<ncrmnt> So far I've just made the LCD work yesterday, but it still needs some love and no suspend/resume.
<avRoogh3> ok. i'd like wheezy on this thing also.
eebrah has joined #linux-rockchip
<ncrmnt> for the LCD
<avRoogh3> ok
<ncrmnt> Then you'll have to do a lot of stuff with the kernel. Namely - identify what stuff you have onboard and build a working kernel
<ncrmnt> Look for gpio-user-drv somewhere on freaktab - it helps quite a lot.
<avRoogh3> i'm fine with kernel compilation. just that this particular flashing toolchain is a bit unknown to me.
<avRoogh3> ncrmnt: ty. i'll do so.
<ncrmnt> So far I got basic kernel booting, mounting debian rootfs from sd card. gyroscope/accelerometer/compas work (at least drivers load, but will need homebrew userspace stuff to work with them).
<avRoogh3> cool. good work.
<ncrmnt> 3g modem works, it's connected over USB.
<avRoogh3> nice.
<avRoogh3> no change of a HOWTO/log of your progress at some point? ;)
<ncrmnt> While now only a few posts on a russian linux community forum. I'll be posting all the details with sources in my blog once I'm through
<avRoogh3> ok super.
<avRoogh3> out of interest what is the vid you have there?
<ncrmnt> Hm, what vid?
<avRoogh3> vendor id
<ncrmnt> Ah, rockchip's vid all the way
<avRoogh3> oh.
<avRoogh3> 0x2207
<ncrmnt> pipo doesn't change any of those
<ncrmnt> yep
<avRoogh3> ok
<ncrmnt> Basically, the thing I like about chinese tablets - they are too lazy to do anything and prefer altering as little as they can from BSP.
<avRoogh3> yes, seems to be the case.

<ncrmnt> deweydb: just try running abd as root
eebrah has quit [Ping timeout: 246 seconds]
<deweydb> thanks, but when i do that i still get an empty list of devices when i do: sudo adb devices
<deweydb> i have the device in USB Debugging mode, and i went to connect to PC and turned that on as well.
<deweydb> i have also tried running: sudo ./rkflashtool p > parm.bin
<deweydb> to dump some settings from the device.
<deweydb> but that also fails to detect my device, with an error: rkflashtool: fatal: cannot open device
<avRoogh3> deweydb: here with my device adb can see it but not rkflashtool.
<deweydb> in osx?
<avRoogh3> but yes, in a similar boat. can't root it either, get a root shell.
<avRoogh3> no, Linux. things are easier on Linux with this sort of thing. more popular among the rooters.
<deweydb> yeah, i've got an ubuntu box, i should just work on there i guess.
<avRoogh3> probably easier.
<avRoogh3> you can be surer to get the vendor id stuff sorted out with udev and lsusb.
<avRoogh3> does anyone here know how, on a non-rooted Android device, i can get a print out of memory ranges? want to try a raw adb push <kernel> on this device.
<deweydb> ok, i will try that. thank you.
eebrah_ has quit [Ping timeout: 246 seconds]
<ncrmnt> avRoogh3: Just reboot to the bootloader, then you can use rkflashtool to dump whatever nand regions you want
<ncrmnt> no matter rooted or not
eebrah has joined #linux-rockchip
<avRoogh3> ncrmnt: if only! i've tried a few dozen combos and reboots. no joy yet.
<avRoogh3> still at it. a couple of rows of keys to try yet though. so not all lost.
<ncrmnt> Yeah, that's the drawback of having a full-sized keyboard ;)
<ncrmnt> well, you can root the device and see if they've left /dev/mem on stock
<avRoogh3> sorry, don't understand. trying to root the device also. no joy there.
<avRoogh3> can't get a root shell.
* avRoogh3 tries more combos.
<ncrmnt> Hm, I rooted mine with this stuff I found on 4pda.ru: http://www.mediafire.com/download/dzx599tkq0rdehl/RK3188+ROOT+Tool.zip
<ncrmnt> Password protected with 'geekbuying.com' (damn that cheap PR).
<ncrmnt> But I'm not sure it will work on your device.
<avRoogh3> cheers.
