AmbiqSuite SDK - Fixes for Known Defects in Release 4.1.0 (Fixes will be integrated in future release)

Grant Whitacre
  • Updated

The below table is a running list of known defects in AmbiqSuite SDK release 4.1.0, 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.

 

General Instructions for applying HAL updates:

  • Copy the updated files into the appropriate HAL folder in AmbiqSuite.
  • Rebuild the HAL project using the same compiler as used for application projects.
    • Use the appropriate project located in one of these folders: \mcu\apollo4b\hal\mcu\gcc\  or \mcu\apollo4b\hal\mcu\iar\  or \mcu\apollo4b\hal\mcu\keil\
    • This will generate a new HAL library file for each compiler, which will be linked into the main application project.
  • If using a separate BSP project, rebuild the BSP before any application uses it.
  • Rebuild application project(s) or example project(s) which should automatically use the new HAL library file.
