Programming and Debugging
Applications for the fpb_ra4e1
board can be
built, flashed, and debugged in the usual way. See
Building an Application and Run an Application for more details on
building and running.
Flashing
Program can be flashed to FPB-RA4E1 via the on-board SEGGER J-Link debugger. SEGGER J-link’s drivers are available at https://www.segger.com/downloads/jlink/
To flash the program to board
Connect to J-Link OB via USB port to host PC
Make sure J-Link OB jumper is in default configuration as describe in FPB-RA4E1 - User’s Manual
Execute west command
west flash -r jlink
Debugging
You can use Segger Ozone (Segger Ozone Download) for a visual debug interface
Once downloaded and installed, open Segger Ozone and configure the debug project like so:
Target Device: R7FA4E10D
Target Interface: SWD
Target Interface Speed: 4 MHz
Host Interface: USB
Program File: <path/to/your/build/zephyr.elf>
Note: It’s verified that we can debug OK on Segger Ozone v3.30d so please use this or later version of Segger Ozone
