02:22 <itdaniher> I have a T428 stick running picuntu 4.5. Trying to track down some USB bugs so I built a custom kernel with marvin with usbmon enabled. Flashing the kernel the seemingly straight forward way gets me nowhere.

02:23 <itdaniher> I've used rkflashtool to put my 4mb kernel where the parameters file is expecting it, overwriting the picuntu kernel, but the stick doesn't boot

02:23 <itdaniher> Do I need to modify KERNEL_IMG in the parameters or make any other changes?

03:34 <naobsd> itdaniher: I don't know about picuntu, but in general you need to make proper kernel.img with mkbootimg or rkcrc

04:07 <itdaniher> hmm, I assumed marvin would do that for me, but grep'ing the source tree indicates otherwise

04:09 <itdaniher> I'll give that a try and report back - thanks for the suggestion!

04:39 <naobsd> I don't know about marvin

05:23 <itdaniher> oh, I'm using the mkkrnlimg app mirrored at https://github.com/jhonxie/rk2918_tools.git

05:23 <itdaniher> it includes rkcrc, suggesting that it handles the necessary bits, but maybe it's out of date?

05:24 <itdaniher> (this is because https://github.com/aloksinha2001/Linux3188 includes a x86 executable with no source - had to scrounge and find something that looked right)

05:26 <itdaniher> it accepts arch/arm/boot/Image and outputs kernel.img, not sure if it does the right stuff in between

07:35 <naobsd> mkkrnlimg in RK's kernel source should be official one. there is no source.

07:37 <naobsd> jhonxie's mkkrnlimg should be derived from my rkcrc

07:39 <naobsd> tools/file formats are not changed long time.

07:40 <naobsd> tools should work properly.

07:41 <naobsd> user needs to use tools properly.

09:37 <arcade|2> I do not use any tools to do the correct kernel image, only what is in the kernel source automatically "make help, make ARCH = arm defconfig here, make kernel.img" and the kernel works.

09:41 <naobsd> you use make, make use tool(mkkrnlimg) to make correct kernel.img

09:41 <arcade|2> im use kernel source from https://github.com/aloksinha2001/Linux3188, i have only one problem the same = " <cyberef> rk30-lcdc rk30-lcdc.1: blank mode:0 <- anyone know why this happens? My screen get blanks 1-2 sec everytime this shows up "

09:42 <arcade|2> so you are right

09:42 <naobsd> user needs to use tools(make or mkkrnlimg or rkcrc or something else which is necessary) properly

09:43 <naobsd> hmm

09:43 <naobsd> user needs to understand/use tools(make or mkkrnlimg or rkcrc or something else which is necessary) properly

09:45 <naobsd> tools does right thing only when it's used properly

09:46 <arcade|2> that ist set in Make file default in kernel when use command make kernel.img

09:49 <naobsd> I don't doubt tool include make and Makefile

09:49 <arcade|2> and the user must first use make mrproper command., "make help "shows all the available default command

09:53 <naobsd> I don't say make kernel.img is only one true way to make kernel.img properly. it also can be done independently.

09:53 <naobsd> anyway

09:53 <naobsd> user need to understand what need to be done and use tools properly

09:55 <arcade|2> I tested last kernel source of https://github.com/linux-rockchip/ working properly and does not appear "screen get blanks 1-2 sec everytime" I think that the source from alok there is something wrong with framebufer

10:00 <arcade|2> you are right cant you use anodher way to create kernel image with command "make kernel.img "is probably easier for those who are beginning their first compilation

10:02 <arcade|2> I'm not an expert I'm just hobbyist, but I read the first manuals penguin

10:17 <arcade|2> source from "linux-rockchip" create fb0 fb1 and reserves memory for them, the kernel source from alok reserve memory for only one fb0 and creates fb0.fb1.fb2.fb3 perhaps that is the problem

10:31 <naobsd> linux-rockchip/rockchip-3.0 is (almost) latest source from RK SDK, it has some changes related to fb

10:32 <naobsd> I don't know detail about these changes, but I think it may affect fb problem

10:33 <naobsd> RK source will not have "modification for some specific product". it may work on some device, and it may not work on some device without modification

10:34 <arcade|2> alok has modified the source and added the support for mali gpu

10:34 <naobsd> mali just work with RK source

10:37 <arcade|2> I myself I added support for wifi rtl8188 for linux-Rockchip-3.0 from alok source and this work ok.

10:40 <naobsd> I know there were some work related to mali done by olegk0

10:40 <naobsd> I don't know other work for mali

10:40 <naobsd> and it seems olegk0 updates his work recently

10:41 <naobsd> https://github.com/olegk0/rk3x_kernel_3.0.36 https://github.com/olegk0/xf86-video-fbdev

10:42 <naobsd> it seems it can be run with .36 kernel now.

10:43 <arcade|2> i have testet from olegk0 old source on my flykast mk809III this work but with problems

10:44 <arcade|2> olegk0 has amodher modification in kernel

10:45 <arcade|2> withouth this modifikation kernel 3188 mali not work properly

10:57 <arcade|2> http://buildroot.uclibc.org/ you can use to build your own kernel + initramfs if you need a kernel with different tools. otherwise is a disaster as you are testing a new driver for mali and Xorg falls.

15:35 <jcarlos> naobsd: One question please. This is my stock misc partition: http://paste.debian.net/72714/. And this is the misc partition of the last manufacturer's firmware update. But currently my misc partition is all 0. I installed recently clockworkmod and did a wipe (factory reset). Do you think that is the reason why my misc partition is all 0 (I did not aplied manufacturer's firmware update)

15:36 <jcarlos> Ups. Last link: http://paste.debian.net/72715/ (manufacturer's firmware update)

15:36 <jcarlos> Lost*

15:37 <jcarlos> And it seems that my tablet came with a misc partition full of backups of "parameter" data.

15:38 <jcarlos> Eight copies to be exact.

15:39 <jcarlos> Yesterday I was wrong, because I thought that my tablet had a misc partition equal to the last last manufacturer's firmware update.

15:41 <jcarlos> And when I saw this morning my backup, and my current misc partition content I realized that I was wrong. So now it seems to make sense the fact that "rkflashtool b" does not boot to recovery.

15:41 <jcarlos> Because my misc partition is currently all 0s.

18:47 <itdaniher> naobsd: I checked the kernel.img produced by 'make kernel.img' against the file manually built with rkcrc - they match.

20:52 <itdaniher> is there any reason why kernels compiled on the device, copied to another computer, and flashed appropriately would inherently not work?

20:53 <itdaniher> the instructions I've seen all rely on cross compiler toolchains

20:54 <karlp> shouldn't make any difference,

20:54 <karlp> just that most people have more power and space on the host rathre than the target

20:55 <itdaniher> yeah, that's what I figured

20:55 <itdaniher> I've built a handful of different images for my t428 using the Linux3188 stock config and the marvin t428 stock config

20:56 <itdaniher> both compressed and uncompressed

20:56 <itdaniher> can't get any of them to boot on my stick, but the picuntu stock kernel works fine

20:58 <itdaniher> I wouldn't even bother if I didn't need the usbmon module so badly

21:04 <itdaniher> anyone have a known-good .config for the t428? there's ambiguity in the Linux3188 package.

21:35 <itdaniher> based upon what my monitor's doing, it looks like the device might be bootlooping

23:02 <karlp> itdaniher: what's this "marvin" thing I've heard about?
