Minimum requirements

The Renesas RA4M3 series devices requires special handling for the TrustZone partition registers of the MCU. This requires certain HW support which is not provided by older J-Link models. The following table lists the minimum J-Link HW version needed to support this MCU.

  • J-Link-OB-S124
  • J-Link BASE V10
  • J-Link PLUS V10
  • J-Link ULTRA+ V4
  • J-Link PRO V4
  • J-Link WiFi V1
  • J-Trace PRO V2 Cortex-M
  • J-Trace PRO V2 Cortex

Later versions (e.g. V10 is listed and current HW is V11) will also work.

Note: Models which are not listed here do not support this MCU.
