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

• MangoPi MQ Pro
• Power Adapter
• A USB to UART Debugger

Installation Steps

Compile Kernel

Fetch the source code:

dd if=milkv-duo_sdcard.img of=/dev/your/device bs=1M status=progress

Modify Makefile to avoid compilation errors:

diff --git a/Makefile b/Makefile
index 57875f1..bc65d72 100644
--- a/Makefile
+++ b/Makefile
@@ -60,7 +60,7 @@ LD = $(TOOLPREFIX)ld
 OBJCOPY = $(TOOLPREFIX)objcopy
 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 firmware via FEL

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

With no SD card attached, connect to the OTG port on board through USB-C

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.
