开发环境构建
基于docker的开发环境

upgrade_tool 是一款专为 Linux 设计的工具，用于烧录原厂固件、RK 固件和分区镜像到 eMMC。它是由 Rockchip 提供的闭源命令行工具。该工具仅支持使用 SPI NAND 闪存进行烧录。
SPI 烧录
cd /media/hao/WorkSpace/EventCamDev/build_luckfox_docker/upgrade_tool_v2.17/upgrade_tool_v2.17_for_linux

ol uf ../../compile/luckfox-pico/output/image/update.img驱动移植
设备树修改
完成
rv1103-luckfox-pico-ipc.dtsi
修改makefile
.MK文件
BoardConfig-SD_CARD-Ubuntu-RV1103_Luckfox_Pico_Mini_B-IPC.mk
同级有一个 overlay
没有找到sc3336 dtsi 使用的地方
- drv_sc3336.c
- drv_sc3336p.c
.rv1103g-luckfox-pico-mini.dtb.dts.tmp 似乎只有一个 dts ，被自动汇总了
BoardConfig-SD_CARD-Ubuntu-RV1103_Luckfox_Pico_Mini_B-IPC.mk 加载了
export RK_KERNEL_DTS=rv1103g-luckfox-pico-mini.dtsrv1103g-luckfox-pico-mini.dts 包含了 rv1103-luckfox-pico-ipc.dtsi
ISP 部分
只需要摘出来
对于一般的相机 需要提供一个IQ（Image Quality）file ,CAC calibration bin files（色差校准二进制文件）
- CAC（Chromatic Aberration Correction）
hpmcu
不知道 hpmcu 对我读取有什么影响
假设我们不考虑 hpmcu
相机驱动移植
rv1106使用的是 5.10的kernel，
编译驱动的指令是
rv1106 和rv1103 几乎共用设备树
minib mipi接口的I2c是 i2c4: i2c@ff470000
[root@luckfox device-tree]# cd i2c@ff470000/
[root@luckfox i2c@ff470000]# ls
#address-cells clock-frequency clocks interrupts pinctrl-0 reg sc4336@30 status
#size-cells clock-names compatible name pinctrl-names sc3336@30 sc530ai@30我们在
sysdrv/source/kernel/drivers/media/i2c
增加 genx320的驱动
/media/hao/WorkSpace/EventCamDev/build_luckfox_docker/compile/luckfox-pico
pi5
:/media/hao/WorkSpace/raspberryPi_manual_build/linux/drivers/media/i2c$
局部修改
# 修改驱动为了生成 ko文件 ，需要
./build.sh driver
# 更改了设备树必须
./build.sh kernel
# build driver 生成的ko文件最终需要存储在 oem文件夹中， 更新到oem 文件夹需要
./build.sh firmware
# 想升级固件必须
./build.sh updateimg
# 实在不知道怎么办
./build.sh all驱动需要手动加载
没有加载其他设备的原因是 没有ko
在 Buildroot 或一些嵌入式系统中，你可能看不到 modprobe，可能因为：
- 模块用
insmod手动加载； - 模块被静态编译进内核；
- 系统太精简，没有引入
kmod包。
rv1103提供了 一个输出时钟的引脚，在i2c的驱动中控制其开始和结束

给内核打patch
v4l2-utils 在 media/libv4l 中 ，可以看看patch如何生效
其他
media-ctl --known-mbus-fmts对于 buildroot中的package 我还是需要删掉已经下载好的package ,才能重新编译
如何制作patch
对于一个没有通过git 管理的仓库
git init
git add .
git commit -m "original"
nano somefile.c # 再次修改
git diff > ~/v4l-utils-feature.patch对于 buildroot 只要在 buildroot-XXXXXX/package/<pkg-name>/ 下添加 .patch文件，就会自动生效

这个其实是
cif_fmt_out 在(vb2_queue) queue->drv_priv 中
rkcif_set_fmt 中会赋值
rkcif_set_fmt在rkcif_set_default_fmt 中使用
rkcif_set_fmt在rkcif_s_fmt_vid_cap_mplane 中使用
rkcif_set_fmt在rkcif_try_fmt_vid_cap_mplane 中使用
rkcif_set_fmt在 rkcif_stream_init中使用
为什么 cif_fmt 是空指针
重新创建镜像
media-ctl 对不对
