  • portmacro and rm_wifi_config header files were wrapped to check for FreeRTOS
  • Wi-Fi configuration macros were included and wrapped to check for baremetal
  • WIFI_IsConnected() function return type was changed from BaseType_t to WIFI_Return Code_t to remove FreeRTOS dependency
  • Users will need to change their return value check (success return value changed from 1 to 0)

Known Issues

• RA0E1:
  • e² studio projects automatically reset compiler optimization to a Size setting on every generate or build operation
    • Add optimization flags (e.g. `-O0`) manually to "Other optimization flags" to override the `-Oz` setting
  • HS400x, ZMOD4xxx and OB1203 sensors cannot be used on RA0E1
  • FS1015 and FS3000 sensors do not support SAU-I2C driver
• Selecting 'Safely Remove Hardware and Eject Media' on Windows and eject the mass storage (PMSC), when using USBX composite device (PCDC+PMSC), the Windows Explorer for PMSC does not disappear.
• PMSC may not work properly when USBX Composite Device (PCDC+PMSC) is connected to specific Linux OS (USB Host).
