The RTCA publishes and sells DO-178C (for airborne software development) and DO-254 (for airborne hardware development). You can purchase both of these essential documents here: www.rtca.org.
But there are also a number of publicly available (but often not-easy-to-find) documents from the FAA and EASA that need to be understood and used in conjunction with the guidance of DO-178C and DO-254. Some of the more important ones are included here for your understanding and downloading convenience:
DER Directory
The FAA DER Directory provides a list of Consultant DERs , by state and technical discipline.
AC 20-152A
This document from the FAA recognizes DO-254 and clarifies its use, adding numerous objectives related to pertinent aspects of modern hardware development. Note that this document is harmonized with the EASA document AMC 20-152A.
AMC 20-152A
