New Features

• Added support for the following boards:
  • VK-RA8M1
  • VOICE-RA2L1
  • VOICE-RA4E1
  • VOICE-RA6E1
• OSPI/DOTF: Added support for wrapped AES keys
• DA14531/DA14535: Added support for Legacy Pairing, Just Works, and Passkey pairing methods as well as initiating pairing from the Peripheral side
• Block Media RAM middleware now supports SDRAM and other memory-mapped RAM devices
• SCI UART driver now supports IrDA communication on supported devices
• Added support for lwIP (lightweight TCP/IP) stack
• Added support for ZMOD4510 NO₂ O₃ sensor
• Support Dual Bank mode for Flash LP with MCUboot
• Added LittleFS support for external Flash
• Added support for GM02S LTE module
  • GM cellular modules are a direct replacement for RYZ. As such, certain EWF and AWS cellular interface usage notes will now reference GM instead of RYZ. Some support for RYZ nomenclature has been retained for compatibility purposes.

Fixes and Improvements

• MCUBoot updated to 2.1.0
• Arm Mbed TLS updated to 3.6.0
• FreeRTOS+TCP updated to 4.2.1
• Segger JLink version updated to 7.98b
• CMSIS-DSP updated to 1.16.2
• RA8x1 Updates to clocks tab
  • Updated the tooltip for ICLK and PCLKs to match the description in the hardware manual
  • RA8T1 Removed unsupported clocks from clock tree (LCDCLK, U60CK, OCTASPICLK)
  • Added missing PLL divider option (PLL Div / 4)
• Additional code size optimizations for TML32 and SAU UART drivers on RA0E1
• Fixed AC6/LLVM warning in rm_motor_driver (Implicit conversion from float to uint16_t)
• Fixed issue in AC6 linker scripts where extra RAM was being allocated for non-secure buffers in NetX projects on devices that don't support TrustZone.
• RA2A2 Fixed issue where the LOCO could be selected as a clock source for RTC (Only Sub-Clock is available)
• RA0E1 Fixed issue where the weekday field was not being calculated in the r_rtc module.
• IICA Fixed build warning in generated code when SDLA and SDAA pins were disabled.
• IICA Fixed issue where transfers were not aborted after receiving a NACK
• Fixed build errors when 'Enable inline BSP IRQ functions' setting is enabled on CM4 devices
• Fixed write value of unused mask invalid bits in r_can driver (applies to FIFO mode only)
• Fixed unresolvable constraint when multiple I3C stacks are added
• Added warnings for certain invalid clock configurations on some devices
• Fixed invalid Developer Assistance callback entry for SAU UART
• CTSU: Fixed issue with capacitive touch filter
• Fixed issue with upgrade mode (Direct XIP) using MCUboot and internal code flash
• Fixed issue with CEU capture
• Fixed TRNG drawing excessive current after use when placed in power down
• DSI: Fixed virtual channel ID for HS sequence operations
• Common FSP API support updated to v1.7.0
• Update MQTT usage notes
• IAR EW projects now correctly select size-based optimization for RA0E1 projects by default
• SMBus now provides unique error codes for different timeout events via rm_comms_callback_args_t::p_instance_args

Deprecations

• FS2012 and OB1203 sensor modules
• RYZ cellular modules
• ZMOD4410
• ZMOD4510

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 a 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).
