Deprecations

• FS2012 and OB1203 sensor modules
• RYZ cellular modules
• ZMOD4410 Odor mode
• ZMOD4510 OAQ 1st Gen mode

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 the USBX composite device (PCDC+PMSC), the Windows Explorer for PMSC does not disappear
• PMSC may not work properly when the USBX Composite Device (PCDC+PMSC) is connected to a specific Linux OS (USB Host)
• EWARM support for RA4L1:
  • EWARM version 9.60.3 does not contain support for RA4L1. To develop with IAR for this device, it is necessary to install support patch files (arm_Renesas_RA4L1_patch_20250117_1.zip) which can be downloaded by EWARM v9.60.3 users from the IAR MyPages system.
