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 and ZMOD4xxx sensors cannot be used on RA0E1
  • FS3000 sensor does 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 a USBX Composite Device (PCDC+PMSC) is connected to a specific Linux OS (USB Host).
• EWARM version 9.70.1 does not contain support for RA0L1, RA2T1, RA4C1, RA8P1 and RA8T2. To develop with IAR for these devices, it is necessary to install a support patch file for which can be downloaded by EWARM v9.70.1 users from the IAR MyPages system
  • RA0L1 (arm_Renesas_RA0L1_20250305_1.zip)
  • RA2T1 (arm_Renesas_RA2T1_20250714_1.zip)
  • RA4C1 (arm_Renesas_RA4C1_20250213_1.zip)
  • RA8P1 (arm_Renesas_RA8P1_20250530_1.zip)
  • RA8T2 (arm_Renesas_RA8T2_20250530_1.zip)
• Due to limitations in RASC, Projects fail to build if there are files with the same name in a build group. To fix this issue, create files with the same name in different build groups. For known issues in the tools, please refer to the respective tool's release notes, e² studio RN

Deprecations

• rm_zmod4xxx and rm_rrh46410 modules have been deprecated as the devices are now EOL
