Hi Christian,
it took some time to add experimental SC2 support. Patches and description you can find in this github repo.
It's good enough to run a cheap S905X4 tv box as headless mini server. Display works as well.
In the next time I'll check which parts of the series are good enough to be mainlined.
I'm currently struggling with a HK1 X4S TV Box (Amlogic S905X4-based), maybe somebody has an idea.
Using a serial console (speed 921600) I was able to wipe the Android on eMMC and get a u-boot prompt.
I can load FDT and kernel image from sdcard, but using booti/bootm the system hangs after just printing "starting kernel ...".
I tried the different typical load addresses, but nothing helped so far.
I'm running out of ideas why I don't see at least a few lines of earlyprintk console output from the starting kernel.
(kernel is self-compiled, works perfectly fine on a S905W-based TX3 Mini)
It seems that the system always uses an own u-boot (don't know exactly where it's stored),
even if I use an image with a different u-boot. Maybe it expects u-boot at different lba's.
As reference I attach the u-boot log. Thanks.
On a side note: Amlogic usb/flash tool doesn't work with this SoC version. With the toothpick reset it reports the expected USB device, but the reported product id is c004, and the available usb/flash tools work with product id c003 only. Even after faking the product id with a kernel hack it didn't work. Maybe the protocol changed.
