• N/A

New Platforms Supported

• N/A

Features/What's new

• Updated development tools:
  • Added support for RPi-Pico uf2 file builder
  • Integrated new size of elf tool to provide correct info with analysis
• Updated libc, now provides ctype functions
• Driver unification:
  • Timer driver now has unified interface for all target platforms
