1. 平台： rk3399 firefly 2g+16g
2. 内核：linux5.15.136 （从内核镜像网站下载）
3. 交叉编译工具 gcc version 7.5.0 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04)
4. 宿主机：ubuntu18.04
5. 需要的素材和资料：链接: https://pan.baidu.com/s/1vUW0wKibbjkXoiHFwhJCsQ?pwd=4krd 提取码: 4krd
准备的情况：
firefly开发板烧写好ubuntu20.04的系统镜像，能正常启动。
我自己这个重新更改了分区表，重新把文件系统单独烧了一下ubuntu20.04.但是不做应该是没有影响的。
内核镜像网站：
Index of /kernel.org/linux/kernel/v5.x/
Index of /kernel/v5.x/
我下载的是5.15.136.tar.xz，我的步骤是生成boot.img(请参考文章解决linux5.15编译时不生成boot.img 的问题-CSDN博客)
目录
一、准备编译
1.1 解压
1.2 编译
1.3 生成一个配置文件
1.4 生成boot.img
二、可以下载到开发板了。
2.1 我是用windows工具进行下载的，
2.2 准备下载
2.2.1 使用RKDevTool软件
2.2.2 上电开发板，进入loader模式
2.3 运行起来？
2.3.1 失败，没有运行起来
2.4 来修改以下这个启动问题
2.4.1 打开dts文件 rk3399-firefly.dts
2.4.2 maskrom模式要多下载一个文件（MiniLoaderAll.bin,网盘中下载）
2.4.3 下载，跑起来啦！！
2.4.4 但是，实际是卡死了！！！
一、准备编译
1.1 解压
新建一个目录（down-kernel）吧，解压到这个目录中。
tar xf linux-5.15.136.tar.xz
因为我使用了共享目录，所以加了前缀（/mnt/hgfs/share-win/），实际你可以把这个包先放到这个新建的目录中，用上述解压命令解压。
1.2 编译
编译的命令
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j6 rk3399-firefly.img
如果aarch64-linux-gnu-不是安装到了系统中，请加上绝对路径，不然会提示找不到工具。
现在这个问题是没有.config 那我现在需要用一个我自己的config，就不用他默认的了。
如果你需要，请到百度网盘下载config-nojc-2023-1024-pcie-wlan-ok2文件
1.3 生成一个配置文件
cp config-nojc-2023-1024-pcie-wlan-ok2 .config
然后还要make menuconfig ARCH=arm64
什么都不用改，直接退出（exit），一定要选择保存，即可
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j6 rk3399-firefly.img
这个错误比较简单了，后面的一些步骤可以参考文章
我这里直接就是修改arch/arm64/Makefile（末尾追加）,加上以下语句
注意：
$(Q)的前面一定是一个table键，不是几个空格合成的。
我把我的Makefile也传到网盘中。如果不行，请使用我的替换掉吧。
MAKE_MODULES ?= y%.img:
ifeq ("$(CONFIG_MODULES)$(MAKE_MODULES)$(srctree)","yy$(objtree)")
echo "111 =" $(Q)$(MAKE)
echo "1112 =" $(PWD)
$(Q)$(MAKE) rockchip/$*.dtb Image.lz4 modules
else
$(Q)$(MAKE) rockchip/$*.dtb Image.lz4
endif
$(Q)$(srctree)/scripts/mkimg --dtb $*.dtbCLEAN_DIRS += out
CLEAN_FILES += boot.img kernel.img resource.img zboot.img
然后，重新
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j6 rk3399-firefly.img
开始编译，不过需要一点时间，耐心等一下，等会还会出现问题
1.4 生成boot.img
编译停止后，提示没有命令
从百度网盘下载mkimg，mkbootimg,resource_tool这三个文件到kernel目录下的scripts目录下，因为是下载下来的，注意执行权限，chmod +x mkimg 等。
我自己做一次拷贝工作，你们应该下载下来
下载之后，再次编译，然后就可以生成boot.img了。
可能大家在编译的时候，还会遇到一些我没有遇到的问题，请自行百度，或者私信留言给我。
二、可以下载到开发板了。
2.1 我是用windows工具进行下载的，
我就需要拷贝到windows里面去。
cp boot.img /mnt/hgfs/share-win/boot-5.15.img
2.2 准备下载
2.2.1 使用RKDevTool软件
【百度网盘中也有该软件】，点击图片中蓝色块，选中你要下载的boot.img文件
注意前面的勾，只有6那里勾上，其他的地方不用勾选，同时0xa000这个地址也要对上。
2.2.2 上电开发板，进入loader模式
按住reset和recovery按键，先 松开reset按键，等到出现loader的时候，松开recovery按键
点击执行，看一下串口能否跑起来
需要连接ttl串口，波特率1500000，8N1
2.3 运行起来？
串口的打印信息，准备好更新了。
2.3.1 失败，没有运行起来
这很正常吧，哪有一次就成功的？？？
2.4 来修改以下这个启动问题
这个图上其实已经提示是没有找到emmc，而它先去找了sdio
那我先把sdio给禁止掉试试。
2.4.1 打开dts文件 rk3399-firefly.dts
linux-5.15.136\arch\arm64\boot\dts\rockchip
改完后重新编译哈，
重新2.2节的操作，不过这个时候，开发板不能进入loader了，而只能进入maskerom（按住reset和recovery按键，先 松开reset按键，等到出现maskerom的时候，松开recovery按键，不出现的时候，这个步骤多试几次）
2.4.2 maskrom模式要多下载一个文件（MiniLoaderAll.bin,网盘中下载）
2.4.3 下载，跑起来啦！！
2.4.4 但是，实际是卡死了！！！
之后没有任何打印输出，hdmi和led灯没有任何反应。
我暂时还没有解决思路，
先试一下看，下回继续分解吧。
