Linux for RK3188 based TV boxes

[mmm123]

Hi,

at the moment I try to compile a kernel base on your .config for recovery.img.
I only find instructions where the 'CONFIG_INITRAMFS_SOURCE' is set to the cpio and at mkbootimg there is a "fake"ramdisk gz...
But at your .config you use "" at 'CONFIG_INITRAMFS_SOURCE'.
Is it a different way and you use at mkbootimg the real cpio? Or how do you handle it?

THX

But that is not my "core" problem, sure there are the kernel (not compressed) and the initramfs at the recovery.img BUT it seems so, there are two different way to "design" the "structure" at the recovery.img:
1.) kernel + initramfs
2.) kernel inkl. the inintramfs + because of that the "fakeinitramfs" (it is empty)
And you use way 1.)
I think way 1.) is like kernel.img & boot.img at NAND and way 2.) is like boot.img includes also a kernel at NAND...

I use "1)", 2) may work or maybe not. Never tried it, as 1) works. If you want to do it diffrently - find some guide how to do it or discover it yourself. Still it is waste of time, as 1) woks for sure and 2) will not give you any advantage.

[no_spam_for_me]

no no, I want to do your way 1.), but I only want to understand the difference (and ofcause explain it at my HowTo "VI) Different devices / kernels" I'm working on (ofcause every time with big THX to you and the other guys ))...

My first working kernel at my first working recovery.img
(System starts up and mount linuxium-ubuntu-rfs)

But I find out, that your Image (kernel) is a little bit smaller than mine.
Is it because of your own toolchain (instead of the 'arm-linux-gnueabihf-gcc')?
And I got some warnings during compilation...

Compilations warnings are usual, don't worry a lot for them.

swap

Hi,

at your post #268 I see, that you use ~291MB at your SD for swap.
=> 31611420672 / 61741056 = 512 Byts/Sektor
=> 60548985 61741055 596035 = 596035 * 512 = 305169920 Byte => ~291MB

Is it used automatically by the kernel or do you have to mount it via /etc/fstab?
I'm asking because at e.g. Ubuntu (linuxium) at restart I see a message with something like that: 'Disabling swap...'

Greetings

Linux doesn't need swap to work, but it is good idea to have at least some amount.
I guess that number "291MB" came from "what is left on device after creating other partitions as round numbers"

In order to use swap you need swap partition or swap file, created as swap - e.g mkswap /dev/xxxx
or mkswap file_name (file must be created first - usualy with dd)
Then you need to run swapnon /dev/xxxx
If you have it in your /etc/fstab, then it is mounted automaticaly at boot.
e.g:
/dev/xxx swap swap defaults 0 0

ecryptfs

Hi,

next problem

I tinker a little bit with ubuntu (linuxium) (btw: I hate this unity, because missing so much...instead of gnome)...

I try to encrypt user home directory:

sudo apt-get install ecryptfs-utils
sudo adduser --encrypt-home

=>

ERROR:  Cannot get ecryptfs version, ecryptfs kernel module not loaded?

YES it isn't at your ko-package...

Now I find

https://github.com/aloksinha2001/Linux3188/tree/master/fs/ecryptfs

So I think I can compile it by my self, but how do I have to do it?
Only 'make' at the subfolder?
Learning by doing,... ok, asking

Greetings

[no_spam_for_me]

Ok, generally my problem was, that I'm working on a 'clean/fresh' system and because of that, of cause no compiled kernel exist, so the files 'modules.builtin' and 'modules.order' doesn't exist too, so the

mkdir 01_out_mod_fw
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 modules_install INSTALL_MOD_PATH=01_out_mod_fw

couldn't work...

Specially it seams so, that nobody try to compile a kernel for rk3066 or rk3188 that support 'ecryptfs' and it seams so, that this is not exist at the '.config' ...

[no_spam_for_me]

Next problem (or problem befor) perhaps someone have a helping hand:
I can not compile modules...
I use alok github (git clone git://github.com/aloksinha2001/Linux3188 ) with mmm123 config...
with

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2

I do not get *.ko's
Because of this the

 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 modules_install INSTALL_MOD_PATH=01_out_mod_fw

couldn't work, so I use

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 modules

and get this output

  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh
  Building modules, stage 2.
  MODPOST 173 modules
ERROR: "GetSNSectorInfo" [drivers/bluetooth/vflash.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

PS -------------

I was hoping that the modules.order is use by the

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 modules

and kick out the

kernel/drivers/bluetooth/vflash.ko
kernel/drivers/bluetooth/hci_uart.ko
kernel/drivers/bluetooth/btusb.ko
kernel/drivers/bluetooth/btsdio.ko

but it is not the fact, because I get the same error, then I delete the modules.order and get the same error...

[no_spam_for_me]

BTW: It seams to be a problem with your ".config" !!!

Same procedure with Galland git and at the end of compiling with

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2

too:

  LZMA    arch/arm/boot/compressed/piggy.lzma
ERROR: "GetSNSectorInfo" [drivers/bluetooth/vflash.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

ich@ich-VirtualBox:~/RK3188/SRC/Galland/Linux3188$

BUT
if I use the "standard" '.config' at the git-clone (and the needing initramfs (git clone --depth 1 https://github.com/Galland/rk30_linux_initramfs.git initramfs; cd initramfs; cp initramfs-3.0.36+.cpio initramfs.cpio)) everything is fine... compiling till the end including the *.ko's...
