OpenOCD Architecture

The OpenOCD library consists of several APIs that build together to provide the support functionality.

The following list shows how these modules are stacked in the current implementation (from bottom to top):

• OpenOCD Helper APIs
  • OpenOCD Types/Portability APIs
  • OpenOCD Jim API
  • OpenOCD Command API
  • OpenOCD Logging API
• JTAG APIs
  • JTAG Core API
  • JTAG TCL API
  • JTAG Command API
  • JTAG Interface API
  • JTAG Minidriver API
• OpenOCD Target APIs
  • OpenOCD ARM Targets
  • OpenOCD Non-ARM Targets
  • OpenOCD MIPS Targets
  • OpenOCD Target Register API
  • OpenOCD Target Image API
  • OpenOCD Target Trace API
• OpenOCD Flash APIs
  • OpenOCD CFI Flash API
  • OpenOCD NAND Flash API
  • OpenOCD Target Flash API
• OpenOCD Server APIs
  • OpenOCD GDB Server API
  • OpenOCD Telnet Server API
  • OpenOCD http Server API
• OpenOCD Application APIs

Obviously, there are some nuances to the stack that are not shown by this linear list of layers.

The List of The List enumerates opportunities for improving or extending the OpenOCD platform.
