AmbiqSuite SDK - Fixes for Known Defects in Release 2.5.1 (Fixes will be integrated in future release)

Grant Whitacre
  • Updated

The below table is a running list of known defects in AmbiqSuite SDK release 2.5.1, along with fixes that can be applied to resolve the defect. The affected files for each fix are referenced and attached.  These fixes will be integrated into a future AmbiqSuite release (Target is Release 2.6)

General Instructions for applying HAL updates:

  • Copy the updated files into the appropriate HAL folder in AmbiqSuite.
  • Rebuild HAL project using same compiler as used for application project.
    • Use the appropriate project located in one of these folders: \mcu\apollo3\hal\gcc\  or \mcu\apollo3\hal\iar\  or \mcu\apollo3\hal\keil\
    • This will generate new hal library file that is linked into main application project.
  • If using separate BSP project, rebuild the BSP first then the Applications.
  • Then you can rebuild your application project which should automatically use the new hal library file.
