修改楼上的 board/mangopi/kit4/v1/dts/linux-v5.4.70/sun8i-v3s.dtsi

添加：

进入Linux，tsc2007(ns2009)一直提示 -6错误，查了一下设备不存在，用 i2c-detect -y 0命令发现，果然不存在 0x48 设备，但是有 0x49 设备：

# i2cdetect -y 0

#

这是怎么回事呢，查看一楼原理图，难道 0x49 是加密芯片DX81C04，
但是看了核心板背面的5脚芯片并没有焊上，
那这个 0x49 估计就是 ns2009 芯片了，对照手册和原理图，发现A0 上拉，地址是要 +1
修改 devicetree.dts，一切正常：

buildroot 快速重新编译某package的方法，
先执行删除 rm output/build/xxxxx/.stamp_built
然后执行 make 即可。

比如需要重新编译Linux，

执行：
rm output/build/linux-5.4.70/.stamp_built ; make

whycan晕哥 LV 9

make menuconfig 删除了某些软件包，但是文件系统里面确没有同步更新，

那么执行以下操作：

rm output/target/ -rf; find output/build/ -name .stamp_target_installed | xargs rm -rf; make

@whycan 试了一下，好像没有用，还是

touch ./output/images/a.dtb     # 防止出现未编译dtb情况
rm ./output/images/*.dtb          # 删除设备树
make linux-rebuild -j8 && make

或者更绝的

rm -rf output/build/linux* 
rm -rf output/build/.linux* 
make

@yuzukitsuru
你的使用姿势不对，应该是要先删除文件 .stamp_built。
