Environment¶

You need following components:

• GR-PEACH
• USB micro-B cable
• J-Link series
• J-Link 9-pin Cortex-M Adapter or equivalent
• Cortex 9-pin header (1.25mm pitch 2x5)

If you do not have them, goto Exporting to e2studio (CMSIS-DAP debug).

Setup¶

Mount Cortex 9-pin header to GR-PEACH¶

Mount Cortex 9-pin header to "JTAG" of GR-PEACH.
Note: 7th pin is not used (without header).

Install Windows serial driver¶

Install latest Windows Serial Port Driver to setup CMSIS-DAP from the link below:
https://mbed.org/handbook/Windows-serial-configuration

Install e2studio¶

Download e2studio 5.0.0 or lator, and install

Build of e2studio environment¶

Exporting to e2studio¶

1. Go to Mbed compiler.
2. Right click at the program you want to export.
3. Select "Export Program"
   
4. Select "Renesas GR-PEACH" for Export Target
