Linux for RK3188 based TV boxes

[tyeo098]

This is from OmegaMoons mk908 source .config file

Default kernel command string :

console=ttyFIQ0 androidboot.console=ttyFIQ0 init=/init

Isnt there supposed to be more here?

[tyeo098]

Aha!!!

I think I've got it.

Well, not really, but I know what the problem is.

I edited the init file in the initramfs.cpio file and rebuilt it with this little line snuck in:

grep -q '\<quiet\>' /proc/cmdline || echo "Loading, please wait..."
[B]sleep 200[/B]
# Note that this only becomes /dev on the real filesystem if udev's scripts

So if it WAS running the init it would hang for 200 seconds.

And it didnt!!!

So it means the kernel is effing up before it gets there, or its simply not detecting the initramfs.cpio file.

ok, try this one:

Is that a whole recovery image to flash?

No dice. Monitors backlight stays on, but nothing on the screen at all.

Note: this is from the config in OmegaMoon's kernel source for the mk908.

CONFIG_LCDC_RK3188=y
CONFIG_LCDC0_RK3188=y
# CONFIG_LCDC0_IO_18V is not set
# CONFIG_LCDC1_RK3188 is not set

What did you attempt to change?

next time build it with "/bin/sh", so you can type commands even if you don't see output

Anyway, google-tv logo is probably built-in into your bootloader, which means it is different from bootloader in my stick. This means it is possible that it doesn't like recovery image. Do you by any chance keep copy of your original recovery image?

I changed exactly what you mentioned above

I dont think so. The GoogleTV logo only shows up when I try to boot this kernel. Otherwise its shows the Tronsmart logo.

Like in this neat video I took lol: http://s154.photobucket.com/user/tye...5ed30.mp4.html

Want to try again? try this:

It is android kernel with my initrd. I doubt, that it will do any good, but lets check if there is at least difference from other kernel.

[tyeo098]

The text says different than what the link is.

WHOA.

WHAT.
THE.
TRUCK.

IT BOOTED MY SD-FS.

Sat at a black screen for all of 30 seconds. Almost gave up.... AND BAM XFCE LOGIN WINDOW!

What did you do?!

[mmm123]

he he, sorry about that - looks like copy & paste forun links is not good idea

I figured as much lol. So I punched in the correct URL and it works!

He he, as I said it is kernel from android packed with slightly modified initd (it doesn't really read command line from /proc/cmdline but from /cmdline, which contains root=LABEL=linuxroot)
This is because in this kernel command line is built into kernel, not passed as parameter.
Anyway, I doubt it would be very useful this way, because of specific android options built into kernel - most likely you won't be able to use network from users other that root. But on the other side, you can copy .modules from android and have really working GPU driver.

[tyeo098]

So I guess my


Default kernel command string :

console=ttyFIQ0 androidboot.console=ttyFIQ0 init=/init

Is wrong afterall.

if you get this from linux, as I said it is just ignored in this modified initrd image.
Working command line string should be
initrd=0x62000000,0x00210000 init=/sbin/init root=LABEL=linuxroot
