Architecure

SPSDK is a library which may be separated into the following layers based on performed functionality:

• Application Layer is a layer allowing SPSDK integration into various applications such as command-line utilities, GUI tools, DevOps/Automation infrastructure which is used in prototyping, production, or testing environments or any application based on specific customer needs. As a part of the library, several command-line applications are included.

• Library Layer abstracts functionality related to images or messages creation and parsing including required security and cryptography functionality.

  • SB - Secure Boot File module.
  • MBI - Master Boot Image module.
  • Crypto - Cryptography module.
  • DAT - Debug Authentication module.

• Protocol Layer packs or unpacks messages and images into a protocol defined by the required device counterpart.

  • BL Host module.
  • SDP Host module.
  • Debug Mailbox

• Communication Layer links SPSDK and connected devices.
