rk3568内核升级移植

RK3568 是一款基于 ARM Cortex-A55 架构的芯片，内核升级移植可以按照以下步骤进行：

1. 下载新的内核源代码，解压到指定目录。
2. 从原有内核中获取配置文件，或者使用默认的配置文件。
3. 在新内核源代码根目录下运行 `make menuconfig` 进行内核配置，也可以使用 `make defconfig` 命令使用默认配置。
4. 运行 `make -jX` 命令进行编译，其中 X 是指定的并发编译数。
5. 编译成功后，在 arch/arm64/boot 目录下生成 Image 文件，该文件即为新内核的二进制文件。
6. 在原有系统中备份原内核，并将新内核的 Image 文件烧录到对应分区。
7. 在启动命令中指定新内核的启动地址和参数。
8. 重启设备，测试新内核是否正常启动。

需要注意的是，RK3568 的内核移植可能会涉及到硬件设备驱动、文件系统等方面的配置和修改，具体操作请参考相关文档和社区资料，或者咨询相关专业人士。

RK3568的buildroot

### RK3568 Buildroot Configuration and Build Instructions

For configuring and building a system specifically targeting the Rockchip RK3568 SoC using Buildroot, several key points need attention to ensure compatibility and functionality of the generated image.

The Buildroot environment allows customization through menuconfig where one can select specific hardware support including processors like RK3568. This selection ensures that all necessary drivers are included within the built root filesystem as well as appropriate kernel configurations[^1].

To start with an RK3568-specific setup:

#### Selecting Target Architecture
Ensure ARM architecture is chosen along with Cortex-A55 CPU type which matches RK3568 specifications. Within `make menuconfig`, navigate under "Target options" -> "Architecture variant", selecting suitable settings for this processor family[^2].

make menuconfig

Under **Target Options**, set:
- **Architecture**: arm
- **Architecture variant (cortex-a)**: cortex-a55.aeabihf

#### Kernel Selection & Configuration
Choose Linux kernel version compatible with RK3568 from available versions provided by Buildroot. After choosing the correct branch or tag corresponding to your needs, apply patches if required for better driver support on newer silicon revisions found in some Rockchip platforms.

Within **Toolchain** section choose proper toolchains supporting hard float ABI since most modern applications expect it when running on ARMv8 cores such as those present inside RK3568 devices:

Select **Enable installation of firmware files into target** so essential blobs needed at runtime will be part of final output images.

#### Board Support Package (BSP)
Incorporate BSP components tailored towards RK3568-based boards via package selections during configuration phase. Look out especially for U-Boot bootloader adjustments ensuring SPL binary generation alongside main u-boot.img file optimized for bootrom loading process used widely across rockchip products line-up.

Finally, compile everything together after saving changes made above steps executing standard make command without any additional parameters unless cross-compilation host machine differs significantly compared against default assumptions embedded within Makefiles structure itself:

This procedure should result in generating artifacts ready-to-use directly upon supported development kits featuring RK3568 chipset while following best practices outlined both internally throughout documentation resources bundled alongside source code repositories plus external guides focusing particularly around similar use cases involving other members belonging same series of System-on-Chips manufactured by Rockchip Semiconductor Co., Ltd.
