Refactoring for Dev 4.8.x broken

[martinayotte]

I've decided to give a try by building new image with the refactoring of 4.8.x.

 

So the image I've done is Armbian_5.21_Orangepipcplus_Debian_jessie_4.8.3.img

I placed it on sdcard and look at the boot using serial debug.

 

Unfortunately, the 4.8.3 Kernel is broken and get stuck the this last line ...

EDIT : Trying to boot it again, it produce sometimes core dumps just after the that last line, starting with :

Unable to handle kernel NULL pointer dereference at virtual address 00000001

EDIT 2 : Oh ? After several boots, it finally get thru ... Could it be DRAM settings ?

 

EDIT 3 : I've build also a Armbian_5.21_Orangepipc_Debian_jessie_4.8.3.img, and unfortunately, it is doing the same ...

[Igor]

My last boot was 4.7.x ... 4.8. could be broken, yap. 

Anyone tried mainline sources?

[zador.blood.stained]

I tested this after updating kernel branch (wanted to check if OTG works), and it worked for me with OPi+2E default settings, but was crashing after switching fdtfile to another board.
