Serial Boot: An alternative way of booting SoC externally

But it provides a big advantage of booting up the SoC from other device when no external memory is available, with the use of simple serial protocols like LIN, CAN, SPI etc.

The hardware configuration to be done in the SoC for implementation of serial booting is very minimal and can be easily provided.

If some issues are seen in the boot code programmed in internal memory then the serial booting will allow the manufacturer and authenticated user to debug the issues, modify the code and put a patch for the correct functioning.

This article deals with the Serial boot protocol and preparing a boot code for the serial booting.
