+# LicheePi 4A Usage
+
+## Basic Usage
+
+Use the following command to compile kernel and dts:
+
+    $ make kernel
+
+Some work can be done automatically:
+
+1. Build the cross compiler
+2. Switch to the selected kernel version
+3. Patch the kernel with patches in bsp/patch/linux/
+4. Use config in bsp/configs/ as kernel config
+5. Compile the kernel
+6. Compile the dts
+
+## Burn
+
+The process of burning images onto the board can be referenced in bsp/burn_tools/README.md.
+
+## DTB
+
+Notice for burning:
+
+The compiled dtb shoule be renamed as light_lpi4a.dtb because U-Boot use this filename as the default dtb.
+
+Or you can modify the default config of /extlinux/extlinux.conf in boot.ext4.
+
+## BIOS
+
+Riscv64 requires a proxy kernel to do some prepare before running the real linux kernel. 
+
+And the proxy kernel currently is replaced by the OpenSBI project.
+
+The OpenSBI used here is specially made for T-Head SoCs.
+
+More detailed instruction is in bsp/bios/opensbi/README.md.
+
+## U-Boot
+
+The U-Boot used here is specially made for T-Head SoCs.
+
+More detailed instruction is in bsp/uboot/README.md.
+
+## Latency testing
+
+After successfully booting the Linux on the board, real-time testing can be performed.
+
+Stress-ng can be used for generating system loads.
+
+I have tested real-time latency with the following stress-ng options:
+
+* stress-ng --cpu 4 
+* stress-ng --vm 8 --vm-bytes 2G 
+* stress-ng --hdd 4
+
+Cyclictest and Ftrace can be used for latency testing and tracing.
+
+Script for reference: 
+
+	$ mount -t tracefs none /sys/kernel/tracing
+	$ cd /sys/kernel/tracing
+	$ echo wakeup_rt > current_tracer
+	$ echo 1 > tracing_on
+	$ echo 0 > tracing_max_latency
+	$ stress-ng --cpu 4 &
+	$ cyclictest --mlockall --smp --priority=99 --distance=0 --duration=30m
+	$ echo 0 > tracing_on
+	$ cat trace
