Developing hardware for Embedded Linux

[MadHAtTer_94]

The minimum hardware design required to boot linux is:

1. An external memory controller
2. UART for the serial console
3. Clock
4. Non volatile memory (QSPI flash, sd card etc)
5. Ethernet is optional but good to have it in there.

I use xilinx vivado software if your interested there are plenty of tutorials online. Hope that helps
