Will vanilla Linux kernel work on Orange Pi Zero?

olegst90

Hi everybody!
I'm trying to build my own Linux for my Orange Pi Zero (Allwinner H2+).
So far I've found out that vanilla U-boot doesn't have a config for Pi zero, but one found on Xunlong's github does.

So I'm building Xunlong's U-boot for orange pi zero and install it on flash. Next, I build uImage from vanilla Linux source with load address 0x48000000 under sunxi_defconfig.
Then I uImage and compiled dtb for orange PI zero in the first partition, and create uEnv.txt with the following contents:

1. bootargs=console=ttyS0,115200 disp.screen0_output_mode=EDID:1024x768p50 hdmi
   
2. aload_script=fatload mmc 0 0x43000000 ${ftdfile};
   
3. aload_kernel=fatload mmc 0 0x48000000 uImage;bootm 0x48000000 - 0x43000000;
   
4. uenvcmd=run aload_script aload_kernel

Copy code

U-Boot starts normally, picks up uEnv, writes "Starting kernel ..." and then silence.

What is wrong? Does vanilla Linux support OrangePi Zero as of now? Is respective dts in linux sources correct and working?

Peek here: https://github.com/armbian/build Vanilla + lots of patches.

Pure vanilla u-boot/kernel will lack functionalities but it should boot.
