J-Link Renesas RX support

J-Link is compatible to the Renesas RX600 series MCUs. All that is needed to use J-Link with a Renesas RX600 series MCU, is an RX Adapter which is available for J-Link, J-Link Pro, J-Link Ultra, J-Link EDU and any other licensed J-Link compatible emulator. The required software can be downloaded from SEGGER's website and used free of charge.

Features

• Supports direct download into flash memory
• Supports software breakpoints in flash memory (Flash breakpoints)
• Seamless integration into the Renesas HEW & IAR Embedded Workbench IDE
• On-chip trace support
• Virtual UART support (C2E support)
• All kinds of events are supported (Execution break, data access, trace break, combintation/sequentation of events)
• 20-pin to standard 14-pin Renesas JTAG connector
• USB 2.0 interface
• JTAG speed up to 12 MHz / 25 MHz (depending on J-Link model)
• No power supply required, powered through USB
• All JTAG signals can be monitored, target voltage can be measured
• Support for multiple devices
• Fully plug and play compatible
• Wide target voltage range: 1.2V - 3.3V, 5V tolerant
• TCP/IP server included, which allows using J-Link via TCP/IP networks
• Target power supply: J-Link can supply up to 300 mA to target with overload protection

Available J-Link RX hardware

RX adapter


All that is needed to use J-Link with a Renesas RX600 series MCU, is a regular J-Link + the 20-pin to 14-pin RX adapter.

Compatible MCUs

J-Link RX support supports all RX-CPUs with RX600 core and JTAG interface. The following devices / device groups are known to be compatible:

• RX610 Group
• RX62N Group, RX621 Group

 

J-Link vs. Renesas E1. What are the advantages of J-Link ?

Getting started

Installing the J-Link USB driver

J-Link RX is compatible to the regular J-Link and uses the same USB driver. In order to install the driver, simply download and install the latest software and documentation pack of J-Link:

J-Link software and documentation pack download page

In order to verify the correct installation of the J-Link USB driver, simply start J-Link commander, a small command line-based tool which comes with the J-Link software.
J-Link commander can be found at Start -> All programs -> SEGGER -> J-Link software version -> J-Link commander. If the installation of the driver was successful and J-Link + target board are connected to the PC, the output of J-Link commander should look like this:

Setup J-Link RX for use in Renesas HEW and IAR EWRX

J-Link RX is fully compatible to Renesas E1 emulator and works with Renesas HEW and IAR Embedded Workbench for RX (EWRX).
The J-Link RX software is a package of DLLs which replace the original Renesas DLLs used for E1/E20 and can be downloaded here:

J-Link RX software download (V4.24c)

For more detailed information how to setup J-Link RX for use with HEW and EWRX, please follow the instructions in the Readme.txt which comes with the software package.

Beta software

Currently there is no new beta version. Please use the current release.

Using J-Link RX with Renesas HEW and IAR EWRX

Since J-Link RX is fully compatible to the Renesas E1 emulator, all features supported by the IDE + E1 can also be used with J-Link RX. J-Link RX has been tested with the following IDEs:

• Renesas HEW
• IAR EWRX

 

Flash programming via J-Link Commander

The built-in Flash loader can be used to program the flash of supported RX devices directly from within the debugger or via J-Link commander. This allows using J-Link for flash programming of smaller production batches. To program the flash via J-Link Commander, a sequence of commands such as the following can be used:

speed 12000                       // Select High JTAG speed
h                                 // Halt target CPU
exec device=RX600                 // Select correct device (RX600, RX62N, RX62T) to enable flash programming
loadbin C:\file.bin,0xFFF80000    // Load program into flash
r                                 // Reset target CPU (not required if all you want to do is program flash)
g                                 // Start target CPU (not required if all you want to do is program flash)
q                                 // Quit

The command can be stored in a script file, which can be executed as follows: JLink.exe
