常見的USB轉(zhuǎn)串口驅(qū)動(dòng)有cp201x，pl2303進(jìn)入kernel，配置menuconfig
#make ARCH=arm menuconfig
選中 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
重新編譯內(nèi)核
make ARCH=arm rk3288-evb-android-rk808-mipi.img -j8
燒錄內(nèi)核固件，上電運(yùn)行，查看驅(qū)動(dòng)是否加載成功
ls /dev/ttyUSB0
此時(shí)可以看到dev目錄下出現(xiàn)設(shè)備節(jié)點(diǎn)ttyUSB0.驅(qū)動(dòng)加載成功。
