xv6 DongshanPI-Nezha STU Test Report

Test Environment

Operating System Information

• Source code link: https://github.com/michaelengel/xv6-d1
• Reference Installation Document: https://github.com/michaelengel/xv6-d1

Hardware Information

• DongshanPI-Nezha STU
• Two USB-C cables

Installation Steps

Compile Kernel

Fetch the source code:

git clone https://github.com/michaelengel/xv6-d1.git

Modify Makefile to avoid compilation errors:

diff --git a/Makefile b/Makefile
index 57875f1..bc65d72 100644
--- a/Makefile
+++ b/Makefile

 OBJDUMP = $(TOOLPREFIX)objdump

-CFLAGS = -Wall -Werror -O -fno-omit-frame-pointer -ggdb
+CFLAGS = -Wall -O -fno-omit-frame-pointer -ggdb
 CFLAGS += -MD
 CFLAGS += -mcmodel=medany
 CFLAGS += -ffreestanding -fno-common -nostdlib -mno-relax

Compile:

make fs.img
make

Flash the kernel with xfel

Install xfel. e.g. on Arch Linux via AUR: paru -S xfel

With no SD card attached, press and hold the FEL button, and connect to both the OTG and DEBUG ports on board through two USB-C cables.

Send the payload through xfel:

xfel ddr d1
xfel write 0x40000000 kernel/kernel.bin
xfel exec 0x40000000

Check the serial port for outputs.

Expected Results

The system boots up normally and allows login through the serial port.

Actual Results

The system boots up normally and login through the serial port is also successful.
