+====================================
+Compiled with
+```bash
+git clone https://github.com/arduino/arduino-renesas-bootloader
+git clone https://github.com/hathach/tinyusb
+cd tinyusb
+# This step is temporary

+
+:rocket: `How to load bootloader`
+====================================
+
+Pull the boot test point low and plug in the Thing Plus RA6M5.
+The board will enumerate as Renesas RA USB Boot.
+
+Then flash the bootloader with [`rfp-cli`](https://www.renesas.com/us/en/software-tool/renesas-flash-programmer-programming-gui#download)
+```
+rfp-cli -device ra -port COM# -p dfu.hex
+```
+
+Otherwise, the same hex file can be loaded through the SWD port (using a Jlink or E2 Emulator for example)
+```
+rfp-cli -device ra -tool e2 -if swd -p dfu.hex
+```
