+# RK3568 BSP Introduction
+
+[中文页]() | English
+
+## 1. Introduction
+
+RK3568 is a general-purpose SOC, quad-core 64-bit Cortex-A55 processor, with 22nm lithography process, has frequency up to 2.0GHz and Mali G52 GPU, support 4K decoding and 1080P encoding. Support mangy interfaces such as SATA/PCIE/USB3.0, an 0.8T NPU for lightweight AI applications. Support dual Gigabit Ethernet ports, LPDDR4 memory, etc.
+
+This project ported RT-Thread on RK3568, you can use the RADXA ROCK 3A version of the RK3568 in low-priced, which can even replace the Raspberry Pi 4B.
+
+## 2. Compiling
+
+Usage ARM Developer GNU ToolChain, it support Linux and Windows:
+
+```plaintext
+https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads/
+```
+
+
+
+Download the `xxx-aarch64-none-elf` of x86_64 hosted platform, set the `RTT_EXEC_PATH` is system environment after decompress the binary.
+
+Enter directory `rt-thread/bsp/qemu-virt64-aarch64` and input:
+
+```plaintext
+scons
+```
+
+
+
+## 3. Execution
+
+RK3568 has different Kernel install methods according to different boardsit, recommend to install into the SD card: ([Official](https://wiki.t-firefly.com/en/ROC-RK3568-PC/hardware_doc.html)|[RADXA ROCK 3A](https://wiki.radxa.com/Rock3/install/microSD)).
+
+After install Kernel, storage the `rtthread.bin` to EFI partition (the second partition), and add this line in the front of `boot.cmd` in this partition:
+
+```shell
+fatload mmc 1:1 0x208000 /rtthread.bin;dcache flush;go 0x208000
+```
+
+
+
+After modifying the script, build a binary script `boot.scr ` in this partition:
+
+```shell
+# Install the uboot-mkimage package on Linux, or use MSYS2 to install the u-boot-tools package on Windows
+mkimage -C none -A arm -T script -d boot.cmd boot.scr
+```
+
+
+
+According to different boards, the serial port can support up to UART0~9, this project uses UART2 ([Official](https://wiki.t-firefly.com/en/ROC-RK3568-PC/debug.html)|[RADXA ROCK 3A](https://wiki.radxa.com/Rock3/dev/serial-console)) by default, the baud rate is 1500000, please make sure that the serial port used supports this baud rate.
