Hi,
I have bought an Banana Pi M3 and want to build my own OS image. What I’ve found is this: https://github.com/BPI-SINOVOIP/BPI-M3-bsp
I cloned the repository and did: 2. Build uboot only. 3. Build kernel only.
Both seem to succeed! But there can I find the u-boot and kernel and how to burn it to my sd card? I know hot to debootstrap, but what needs to be done before to prepare the sd card with partitions, kernel and u-boot?
Thank you for your help! Alex
+1 I was wondering the same.
Have a look here:
If this doesn’t help i can write a step by step how to for you.
Yes please, a step by step howto would really help! Thank you 
Please do it!
I’d love to cook a raw minimal Debian image with updated sources and I’d love to know the steps to make one.
anyone? Pls help me/us! A small howto would be really useful.
