Serial Connection Configuration
|
|
|
|
|
--------------------------
|
|
|
|
|
1. GRROSE board needs to be connected to PC terminal, using USB to Serial Chip.
|
|
|
|
|
2. Connect TX of USB to serial chip to RX of SCIX(0,1,2,5,6)
|
|
|
|
|
3. Connect RX of USB to serial chip to TX of SCIX(0,1,2,5,6)
|
|
|
|
|
4. Connect GND to GND pin.
|
|
|
|
|
5. Configure Teraterm to 115200 baud.

LEDs
|
|
|
|
|
====
|
|
|
|
|
|
|
|
|
|
The RX65N GRROSE board has 2 LED's, 1 Power LED(LED3) and 2 User LED's(LED1, LED2),which are enabled through software.
|
|
|
|
|
|
|
|
|
|
If enabled the LED is simply turned on when the board boots
|
|
|
|
|
successfully, and is blinking on panic / assertion failed.

You can use ping to test for connectivity to the host (Careful,
|
|
|
|
|
Window firewalls usually block ping-related ICMP traffic). On the
|
|
|
|
|
target side, you can:
|
|
|
|
|
|
|
|
|
|
nsh> ping 10.75.24.250
|
|
|
|

Debugging
|
|
|
|
|
==========
|
|
|
|
|
|
|
|
|
|
1. NuttX needs to be compiled in Cygwin.
|
|
|
|
|
|
|
|
|
|
The following Configuration needs to be set, in order to do source level debugging.
|
|
|
|
|
|
|
|
|
|
CONFIG_DEBUG_SYMBOLS = y (Set this option, using menuconfig only, DO NOT Enable this as default configuration).
|
|
|
|
|
|
|
|
|
|
2. Download & Install Renesas e2studio IDE.
|
|
|
|
|
3. Load the project(NuttX built on Cygwin) as Makefile project with existing code
|
|
|
|
|
4. Right click on the project, and select Debug Configurations.
|
|
|
|
|
5. The binary(NuttX) needs to be loaded using E1/E2 Emulator.
|
|
|
|
|
6. Select the Device name as R5F565NE and Emulator as E1/E2(whichever is being used)
|
|
|
|
|
7. Select Connection type as FINE.
|
|
|
|
|
8. Load and run the binary.

Below are the steps mentioned to flash NuttX binary using Renesas flash programmer tool(RFP).
|
|
|
|
|
|
|
|
|
|

|
|
|
|
ifeq ($(CONFIG_MOTOROLA_SREC),y)
|
|
|
|
|
@echo "CP: $(NUTTXNAME).mot"
|
|
|
|
|
$(Q) $(OBJCOPY) $(OBJCOPYARGS) $(BIN) -O srec -I elf32-rx-be-ns $(NUTTXNAME).mot
|
|
|
|
|
endif
