6. On a Linux terminal start the command
sudo dfu-util -a "sf_cm3" -D FIRMWARE
Replace FIRMWARE with the file name of the software to install.
7. When the download process is complete, press Ctrl+C on U-Boot.
8. If the autoboot command was already configured, go to step 10.
9. Set the autoboot command in the U-Boot:
setenv bootcmd "sf probe && sf read 0x4000000 d0000 90000 && sf read 0x8ffe0000 b0000
20000 && sf read 0x80008000 1d0000 f00000 && rzn1_start_cm3 && sleep 4 && bootm
0x80008000 - 0x8ffe0000"
10. Save the command to the flash: saveenv
11. Reset the device
It is also possible to debug the RZ/N1D communication core. The steps accored to section 3.5.1.1, but
the boot command has to be set to
setenv bootcmd "mw 0x04000004 1 && rzn1_start_cm3 && sleep 20 && sf probe && sf read
0x80008000 1d0000 f00000 && sf read 0x8ffe0000 b0000 20000 && bootm 0x80008000 -
0x8ffe0000"
This delays the boot of Linux about 20 seconds. Meanwhile the CM3 core has to be startet.
3.5.4 Core To Core variant – RZ/N1D (Application Core)
The user application runs on the Linux system of the CA7. Its binary must be created by GCC and
downloaded to the RZ/N board manually.
Note: It is recommended to maintain a consistent boot order of the communication and the
application core. Therefore it is advised to always start the R-IN engine / Cortex-M3
(communication core) first and boot the Cortex-A7 (application core) after the
communication core has finished its initialization.
3.5.4.1 Building and downloading the user application
The following steps describe, how to build a binary and download it to the RZ/N1 board.
1. Navigate with the terminal of a Linux PC to the project of the application core at
goal/projects/goal_pnio_rpc_lib/01_simple_io/gcc.
2. Start the build process by executing the Makefile by typing
make
3. Select as target platform “rzn_a7_demo_board”.
4. Power up the board and wait till Linux booted successfully.
5. Copy the created binary file build/rzn_a7_demo_board/goal_rzn_a7_demo_board.bin to the
RZ/N1 board by e.g. secure copy (scp).
6. Copy the application corresponding library
goal/projects/goal_pnio_rpc_lib/00_lib/gcc/build/rzn_a7_demo_board/libgoal_rzn_a7_demo_
board.so to the RZ/N1 board by e.g. secure copy (scp).
7. Start the binary file on the target by typing the commands
export LD_LIBRARY_PATH=.
