NEO Core, Fusing SD Card After Building U-boot & Linux

Moderators: chensy, FATechsupport

I have successfully completed building U-Boot and Kernel for my NanoPi NEO Core (512MB RAM, 8GB eMMC) by following the instructions at:
http://wiki.friendlyarm.com/wiki/index. ... 5/H3/H2%2B

However, until now, I am not able to fuse the binaries into an SD Card image. The instructions section about this step is neither complete nor clear in this regard.

First it asks to burn u-boot-sunxi-with-spl.bin which I have done, but then it just ask to update the SD Card with zImage and kernel modules without any information on how to partition the SD-Card or build the rootfs partition.

All my trials of different combinations had failed. What happens is that after inserting the SD-Card, the system on the serial monitor seems like it starts to look for eMMC but not the SD Card and then do nothing.

It worth to mention that the board is new and it works perfectly with the official image with the same SD Card.

or update the kernel in a working distribution and customize it for yourself

Simple but powerful Debian like OS build system with (upstream) kernel + lots of dedicated patches for those boards. not found in buildroot or elsewhere.
