- MultiZone: loaded to flash via OpenOCD => 0x2000_0000;
- ZSBL: loaded to flash via OpenOCD => 0x2080_0000;
- FSBL: loaded to mSD card => 0x0800_0000 L2 LIM;
- BBL Linux: loaded to mSD card => 0x8000_0000 DDR;

Download Hex Five's reference toolchain or build your own:
-
GNU Embedded Toolchain - v2018.12.26: http://hex-five.com/riscv-gnu-toolchain-20181226
-
OpenOCD - v2018.12.26: http://hex-five.com/riscv-openocd-20181226
Install the prebuilt RISC-V toolchain for Linux:
sudo apt update
sudo apt upgrade -y
sudo apt install git make default-jre libftdi1-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4
wget https://hex-five.com/wp-content/uploads/riscv-gnu-toolchain-20181226.tar.xz
tar -xvf riscv-gnu-toolchain-20181226.tar.xz
wget https://hex-five.com/wp-content/uploads/riscv-openocd-20181226.tar.xz
tar -xvf riscv-openocd-20181226.tar.xz
git clone https://github.com/hex-five/multizone-sdk
sudo apt-get install libusb-0.1-4
sudo apt-get install picocom
sudo apt-get install screen
Note: for the Ubuntu 19.04 LTS you may need to install the libncurses5 package.
sudo apt-get install libncurses5:i386 sudo apt-get install libncurses5:amd64
Add environment variables and a path to allow the Makefiles to find the toolchain by editing the ~/.bashrc and placing the following text at the bottom of the file:
export RISCV=/home/<username>/riscv-gnu-toolchain-20181226
export OPENOCD=/home/<username>/riscv-openocd-20181226
export PATH="$PATH:/home/<username>/riscv-gnu-toolchain-20181226/bin"
Note: <username> shall be replaced by your username.
Close and restart the terminal session for these changes to take effect.
- Download the prebuilt MultiZone for Linux package from Hex Five's website (http://hex-five.com/multizone-linux-20190808):
$ wget https://hex-five.com/wp-content/uploads/multizone-linux-20190808.tar.xz
$ tar -xvf multizone-linux-20190808.tar.xz
$ cd multizone-linux-release/
- Flash the Board (Multizone & ZSBL):
$ ./flash.sh board
- Flash the SD Card (FSBL & BBL)
$ ./flash.sh </dev/sdX>
Note: </dev/sdX> shall be replaced with the device name of the SD card (e.g, /dev/mmcblock0 or /dev/sda).
(If you just want to test the Multizone for Linux SDK reference image, please skip directly to "Demo".)
- Clone the MultiZone for Linux SDK repo:
$ git clone https://github.com/hex-five/multizone-linux
- Build the MultiZone SDK for the U540:
$ make BOARD=U540
- Load the MultiZone SDK image to flash (0x2000_0000):
$ make load BOARD=U540
The MultiZone system contains four zones:
- Zone 1: Multizone demo console accessible via Linux device /dev/multizone1;
- Zone 2: Multizone demo console accessible via Linux device /dev/multizone2;
- Zone 3: Multizone demo console accessible via UART 115200/8/N/1 (expansion board);
- Zone 4: MultiZone Heartbeat LED D4 and message echo;
Set the mode select switches to '0001':
USB LED Mode Select Ethernet

Connect to the UART by setting the baudrate to 115200/8/N/1:
$ picocom /dev/<ttyUSB_DEVICE> -b 115200
Note: <ttyUSB_DEVICE> shall be replaced with the correct UART device name (e.g, ttyUSB0, ttyUSB1).
You should be able to see on the terminal the FSBL loading the BBL image:
SiFive FSBL: 2019-08-7-d8f6e2f
Using FSBL DTB
HiFive-U serial #: 00000068
Loading boot payload.........................
Once the BBL boots Linux, Linux starts executing:
bbl loader
...
- Login to Linux using the root accout:
Welcome to Buildroot

- Connect to Zone1 via Linux:
# screen /dev/multizone1
You shall be able to see and operate the terminal running on Zone1:

- In case the HiFive Unleashed U540 is connected to the Microchip / Microsemi Aloe Vera kit, it's possible to operate Zone3 via the UART (J36) available on the expansion board:
$ picocom /dev/<ttyUSB_DEVICE> -b 115200
Note: <ttyUSB_DEVICE> shall be replaced with the correct UART device name (e.g, ttyUSB0, ttyUSB1).
You shall be able to see and operate the terminal running on Zone3:

# screen /dev/multizone1Open a second SSH sessions as described above then connect to Zone2 via:
# screen /dev/multizone2To terminate screen sessions type: crtl-a k.
