[help] Trying to build a close to mainline image

[erreip2221]

Hello everyone,

So I'm new to the SBC world with my pine64+.
Therefore I did a lot of reading about bootloading, rootfs and all the crap about allwinner's BSP and boot0 firmware...

 I compiled a lot of stuff, but ended up figuring it would be easier to use the "base" image from apritzel. Problems are : 
- I don't have my pine with me to experiment
- I would like to make sure about what I need to do exactly

By using dumpimage of the boot script my understanding is the following:
- I can keep the dtb file which will be picked up through the ${fdtfile} in the boot script
- I should add my kernel in the image file as "uImage" or in "boot/uImage"
- the rootfs should be on the second partition of the image (therefore on mmcblk0p2 once on SD

I have an AARCH64 rootfs using a qemu debootstrap I found in one the pages
I know the kernel has a lot of shortcomings, but ethernet, SD should be ok if ssh agrees to work out of the box...

I also need to figure out how to setup initial user accounts on the image.

That's all 
Any help appreciated
