+### Debugging Renesas RX65N
 
 Create a new "Renesas Debug" project. Choose the "E2 Lite" emulator and the built `wolfboot.elf`. After project is created open the "Debug Configuration" and change the debugger interface from "JTAG" to "FINE". Run debug and it will stop in the "reset" code in `boot_renesas_start.S`. If using Big Endian change endianess mode in "Debugger -> Debug Tool Settings -> Memory Endian -> Big Endian".
 
-### Debugging Renesas RX65N in terminal:
-
-Requirements:
-* `e2-server-gdb`: Included with e2Studio
-* `rx-elf-gdb`: Included with e2Studio or rx-elf toolchain.
-
-Note: On Ubuntu 22 `rx-elf-gdb` requires ncurses5 (use `apt-get install libncurses5`).
-Note: The GDB server is inside an Eclipse plugin "com.renesas.platform_1733799057.jar" and will not be extrated until first used in e2Studio.
