[RK3399 ] 将usb转串口驱动编译

1.设置usb转串口

 

针对不同的芯片还有cp210x.c 和 pl2303.c 进行处理如下：

首先进入sdk的kernel目录

make menuconfig

选中 Device Drivers > USB support > USB Serial Converter support下面的
<*>   USB CP210x family of UART Bridge Controllers
<*>   USB Prolific 2303 Single Port Serial Driver

因为要编译成boot.img和resource.img来烧写，所以选中*即可

 

2.编译

cd kernel

make ARCH=arm64 rk3399-sapphire-excavator-edp.img -j12
