Fixes and Improvements

  • Added SPI support to r_ble_gtl

  • r_pdm: Fixed sample rate calculation in the configurator. The calculation was off by a factor of 2 due to decimation performed by the low-pass filter in hardware

  • Simplified OSPI_B MDF configuration and constraints related to DOTF support

  • Resolved an IAR compiler build failure that occurred when using the PQC crypto module with RA8 devices

  • Enabled PLL startup when HOCO is selected as the clock source and MOSC is not populated

  • Fixed edge case in PQC where a NULL check prevents a valid 0x00000000 address from being used as a pointer

  • Fixed MCUBoot build failure when the Flash LP Bank Swap setting is configured to Instant

  • Corrected the configuration for L3 fowarding feature in r_layer3_switch

  • Updated module version information of the RSIP Protected Mode driver

  • Added list of HAL drivers and supported RA MCUs to the FSP User's Manual

  • Added support for 8 byte transfer size option in DTC

  • Added support for 8 byte transfer size option in DMAC

  • Added TFLM support on RA MCUs without NPU

  • Added ML-DSA support for MCUboot signing

  • r_sci_b_uart: Added new configuration parameter 'Extra > TXI/TEI Synchronization Delay Cycles' to address issue where the last transmit data was not always output when SCICLK was much slower than PCLK

  • Removed AES-XTS key injection feature for RSIP-E31A according to the support policy.

  • Added PM FOC motor algorithm support in Motor Control Middleware

  • Added Motor Tuning module for permanent magnet (PM) motors in Motor Control Middleware

  • Moved GTETRGx pins from GPT to GPT_POEG in RA6T2 Pin page

  • Added support of UART_EVENT_TX_DATA_EMPTY event for SAU UART

  • Updated r_rmac diver to support L2 over L3 fabric

  • Secure and privilege attributes for NPU to access memories shall be configured via properties

  • Updated control procedures for RSIP-E31A PM driver to code size reduction version

  • Fixed GCC C++ build warning in ThreadX port

  • Updated Segger JLink version to 9.14

  • Added constraint to check etherc buffer to netxduo

  • Fixed error on EtherCAT SSC Port when adding one more timer instance

Known Issues

  • Solution Projects (TrustZone, Multicore):
    • There are issues related to pin configuration synchronization between projects in e2 studio 2025-12. Refer to this document for workarounds
  • 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 USBX Composite Device (PCDC+PMSC) is connected to specific Linux OS
    (USB Host).
  • EWARM version 9.70.2 does not contain support for RA0E3. To develop with IAR for these devices, it is necessary to install a support patch file for which can be downloaded by EWARM v9.70.2 users from the IAR MyPages system
    • RA0E3 (arm_Renesas_RA0E3_20260106_1.zip)
  • When importing projects in e2 studio that were created using a previous toolchain version be sure that the version specified in the project is integrated (Window->Preferences->Renesas->Renesas Toolchain Integration) or select the appropriate toolchain version if upgrading the project to a later FSP version.
  • When upgrading RA6T2 projects to FSP 6.4.0, the GTETRGx pin assignments might be lost, please re-assign the pins manually.
  • When upgrading RA0E1/E2/L1 projects to FSP 6.4.0, the SAU_SPI00 pin group might be changed, please restore the pin group manually.
  • For known issues in the tools, please refer to the respective tool's release notes e2 Studio RN.
