bare metal project

[davef]

There is a "bare metal" subsection on the RaspberryPI forums that should deal with the topics and processes that you need to understand and use.

The "bare metal" section in the Raspberry Pi forum can give you some ideas on how-to program an ARM CPU. But for programming the Allwinner SoC we need to have details on how to create a startup.S (or similar). The ideal option is not using the U-Boot loader and have our own 'bare metal' loader. Any ideas are much appreciated.

The above is mostly Linux, it does not give the details for baremetal programming.

I’ve found the following:
https://github.com/dwelch67/allwinner_s ... /master/H3
https://github.com/trebisky/orangepi {Allwinner H3}

Both are still using U-Boot.

I have a complete baremetal environment here -> https://github.com/vanvught/rpidmx512
This includes: I2C, SPI, Ethernet, GPIO

I still use U-Boot. This is basically the Allwinner supported method. I am not eager to invent the wheel in writing my own SPL.
