Software

Code Base

• Git
  • Repositories: ESA-24 (class), ESF/NXP (code, instructions, labels, drivers)
  • Learn git concepts, not commands.

Build Chain

• MDK-ARM Lite Integrated Development Environment (IDE)
  • Getting Started with MDK  
  • Download page – Use the Download MDK-Core link. Skip license activation to use the MDK-Lite edition.
  • App. Note 232 covers installation and use, but its PDF instructions are out of date. Please refer to Practical Homework 1 for updated instructions.
  • App. Note 298 Migrate ARM Compiler 5 to ARM Compiler 6

Appendix: Unused Tools

Code Analysis

• Call Graph Tool (TBD)
  • Must be located in ESA-23/Tools/Calls
  • Requires Graphviz and Python
  • Keil MDK-ARM: Target Options
    • Linker -> Misc Controls: –callgraph_file=mycallgraph.txt –callgraph_output=text
    • Listings -> check Linker Listing box.
• Get Regions: PC-Sampling Profiler (TBD)
•  Ghidra
  • To create a new project:

1. 1. Start Ghidra
   2. File->New Project (Ctl-N)
   3. Select Non-Shared Project, Next
   4. Define Project Name, change Project Directory if needed
   5. Click on green Ghidra head in Tool Chest (upper left)
   6. File->Import File (I) to select the .axf from MDK project’s Object directory
   7. Import … OK.
   8.  OK for import results
   9. Answer Yes to “… has not been analyzed. Would you like to analyze it now?”
   10. In Analysis Options -> Analyzers, select DWARF, then in Options check Preload all DIEs (the last box)
   11. Then select Analyze.
