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:
