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 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.
