SiFive HiFive Unleashed

Instructions for cross-compiling and running wolfSSL on the HiFive Unleashed board.

Board SiFive HiFive Unleashed Board

SiFive Freedom U540 SoC at 1.5GHz

Getting started guide: https://sifive.cdn.prismic.io/sifive%2Ffa3a584a-a02f-4fda-b758-a2def05f49f9_hifive-unleashed-getting-started-guide-v1p1.pdf

Make sure your ethernet is attached and power up board. You can connecct the micro-usb to get a UART console that will display the DHCP IP address. Default login password is "sifive".

Building Freedom-U-SDK

git clone https://github.com/sifive/freedom-u-sdk.git
cd freedom-u-sdk
git submodule update --recursive --init
make

See freedom-u-sdk/README.md file for instructions on updating the SD card U-Boot and Linux image.

Installing U-Boot

Insert SD card from Unleashed into host and determine the assigned character sequence (X) for the media.

From freedom-u-sdk directory:

sudo make DISK=/dev/sdX format-boot-loader

# Copy U-Boot .fit image to first FAT partition (32MB)
sudo mkdir /media/hifiveu_boot
sudo mount -t vfat /dev/sdX1 /media/hifiveu_boot
cp ./work/image-<GITID>.fit /media/hifiveu_boot/hifiveu.fit
sudo umount /media/hifiveu_boot

# Copy Linux FS
sudo dd if=./work/hifive-unleashed-<ID>.gpt of=/dev/sdX2 bs=1M

Note: Make sure S1 Switch 5 (MSEL2) is OFF, rest ON (MSEL=1011) to boot from SD

Installing Debian

Insert SD card from Unleashed into host and determine the assigned character sequence (X) for the media.

From freedom-u-sdk directory:

sudo make DISK=/dev/sdX format-demo-image

Building wolfSSL

Make sure you are using wolfSSL sources based on this PR https://github.com/wolfSSL/wolfssl/pull/2456 The PR 2456 includes a patch to wolfssl/wolfcrypt/types.h to detect 64-bit types based on the __riscv_xlen macro.

Cross Compiling

This example assumes the wolfssl root directory is along side the freedom-u-sdk directory. If not then adjust paths.

~\
	wolfssl
	freedom-u-sdk

./configure --host=riscv64 \
	CC="`pwd`/../freedom-u-sdk/work/buildroot_initramfs/host/bin/riscv64-sifive-linux-gnu-gcc" \
	--with-sysroot="`pwd`/../freedom-u-sdk/work/buildroot_initramfs_sysroot/" \
	--disable-shared \
	--enable-sp \
	CFLAGS="-mabi=lp64d -march=rv64imafdc"
make

Copy files to device (replace IP address):

scp ./wolfcrypt/test/testwolfcrypt root@192.168.0.144:~
scp ./wolfcrypt/benchmark/benchmark root@192.168.0.144:~
scp ./examples/client/client root@192.168.0.144:~
scp ./examples/server/server root@192.168.0.144:~

# manually `mkdir certs` on target
scp ./certs/* root@192.168.0.144:~/certs

Native Compiler

./configure --enable-sp
make
