Hello all,
at Elimo Engineering we have designed Impetus, a SoM that shares the Allwinner S3 SoC with the PineCube. Our first supported platform is (going to be) Buildroot.
Given the similarities of the two, and the general lack of support for the S3, we have decided to do double purpose and integrate support for the PineCube into Buildroot.
You can find the repo on our GitHub account and build instructions in the board support directory readme.
The most important thing that this provides is support for the S3's DDR3 in u-boot. Unfortunately mainline u-boot does not have that yet.
Since we don't have a PineCube ourselves, this is unfortunately untested, but it should get a functional system that boots to a console on UART0. It's pretty fast too, getting there in 1.5 seconds from u-boot to login prompt.
All in all, I think this could be a good starting point for further development.
