Hey Sergey,
Thanks for mentioning, but I think the problem has nothing to
do
with those patches. I tested them with the v4.15.0 Kernel since
this
is the last stable release and we are right now in the merging
window.
I tested the latest mainline, without those patches and the
kernel
is not booting (I can't see any uart output).
Thanks,
Philipp

This patchseries fixes the bananapi m1 devicetree, to be

The first two patches update/improve the devicetree and the

Thanks
same problem, but after applying the patches my device is till
hanging.
Can you please share a bootlog? Here is mine [1]. As you can see
I'm
able to boot.
I build it with this branch [2]. For testing you should replace
the
dtb and the uImage/zImage

My dmesg is very similar to yours unless it hangs on the last line
[1].
For this test I used kernel from tag v4.15 with no additional
patching.

For me it looks like you have a different kernel and also an different
dtb that you patch! And you are applying also a fixup script.
These patches should be applied on top of linux mainline.
fixup script:
Applying kernel provided DT fixup script (sun6i-a31s-fixup.scr)
Linux versions:
4.15.0-00003-g1bbe5edde691 vs 4.15.0-sunxi-dirty
In addition to that you are also booting into fb/hdmi.
If you use my branch (uImage and dtb) and replace the current boot.cmd
with this (to get the boot.scr you need to use mkimage) it should work:
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait
panic=10
load mmc 0:1 0x43000000 ${fdtfile} || load mmc 0:1 0x43000000
boot/${fdtfile}
load mmc 0:1 0x42000000 uImage || load mmc 0:1 0x42000000 boot/uImage
bootm 0x42000000 - 0x43000000
ok, I confirm that your patches are not related to the issue. It is the
problem with sun4i drm / hdmi which is not working on bpi m2.
Thanks
