Deprecations

• The following modules/features have been deprecated and will be removed in FSP v6.0.0:
  • FS2012 and OB1203 sensor modules
  • RYZ cellular modules
  • ZMOD4410 Odor mode
  • ZMOD4510 OAQ 1st Gen mod

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 a specific Linux OS (USB Host).
• EWARM support for RA0E2 and RA2L2
  • EWARM version 9.60.4 does not contain support for RA0E2 and RA2L2. To develop with IAR for these devices, it is necessary to install the support patch file for RA0E2 (arm_Renesas_RA0E2_20240715_1.zip) and RA2L2 (arm_Renesas_RA2L2_patch_20240510_1.zip), which can be downloaded by EWARM v9.60.4 users from the IAR MyPages system
• For known issues in the tools, please refer to the respective tool's release notes e² studio RN
• rm_rrh62000 does not support r_iic_master on RA8 series MCU

Note

• Updated lwIP HTTP Server usage notes to clarify HTTPS is not currently supported
