Kernel dev [RK3288]

[d33]

I've FINALLY got round to getting this box set up and compiling.

I've built a kernel and tested it, a few errors but I'm sure it will be all smooth soon.

I can see Mo123 has already done great work, is there anything extra needed? I'll build my kernel anyway but would be great to get an idea on priorities

My first one will be optimizing DDR and CPU

[ICU]

Stable over clock of ddr3 and CPU would be sweet.

Leolas has included nfs on his custom 3288 kernel ... a must have to a kernel

[d33]

I've isolated the two main bugs in my kernel act4486 and rk1000 i2c related.

Once fixed I'll publish my alternative.

right on my friend.

OK - all fixed.

The DDR3 is set to 456 MHz and CPU to 1.8 GHz.

What do we want? What has been tried?

"stock" 1800 CPU / 500 GPU / 456 DDR3 = 37,221 on Antutu @1920 x 1080 res
"Overclock" 1992 CPU / 600 GPU / 600 DDR3 = 39,593

I'll up the RAM to 667 and also try to compile with 4.9 xcompiler

*edit* Frequency is clipped to 648 when I set 667. Antutu = 40,015

Finally have gotten my Firefly source code downloaded. Can you steer me to the proper files I need to modify for o/c. Set up with heat sink and cooling fan.

In the device tree source, which makes life a lot easier

try to compile with 4.9 xcompiler

Doesn't boot with standard xcompiler, even after fixing a couple of always-inline errors it hangs on boot logo

First Test Kernel

OK, here's my first attempt. Test at your own risk. It will need a boot.img without kernel to work. You can test by checking the compile string in /antutu details. It will have my machine name (gargleblaster)

Details:

CPU - 2.0 GHz
GPU - 600 MHz
DDR - 650 MHZ

Antutu 5.3 = 40k

HDMI works fine but I think TV out needs work (can't test)

Added a few extras like NTFS, NFS, CIFS/Samba but can't add HDMI IN support as it doesn't exist in the source I have ??

... but can't add HDMI IN support as it doesn't exist in the source I have ?? ...

I think because it doesn't exist at the SoC... The so called "HDMI IN" seems to be nothing else than a switch at the HDMI which will be execute by an APP at android (if I'm not wrong, this is why it doesn't exist at the Linux at the moment)...

The source Mo123 is compiling from has the driver (LT8641EX) but I'm compiling from Firefly which doesn't seem to have it even though it is mentioned on their website

[no_spam_for_me]

Ahhh, ok, that means they handle it via I2C (and GPIO)....
But I don't understand why they talk about LT8641EX (I think it has to be at minimum LT8641SX but it is also HDMI 1.4 ... maybe the same driver) http://www.lontiumsemi.com/English/product1.asp

It try to identify the chip at this picture of the pcb (the best one I can find) and it seems to be the SX

Good job! Nice to see increasing support for our boxes.
Does it overheat, or is the voltage tweaked too? Can it be safely run without active cooler?
You should get in touch with mo123 or finless to make one kick-ass rom
btw, I thought the gpu is clocked @700mhz by default. Obviously not.
Thanks and keep up the good work.
