PSDK在rk3568上移值,串口有时不通
pSDK3.9.1, 在rk3568上移植。有e-port开发套件。前面在虚拟机上通过ft232 usb-ttl跑PSDK demo ok。
现在移植到rk3568上,e-port板和rk3568直接用杜邦线连接串口,上周在同样的rk3568板上正常跑demo没问题,在另外一个rk3568上跑同样的demo,一直显示串口:[20.559][adapter]-[Info]-[DjiAccessAdapter_Init:215) Try identify UART0 connection failed. Probably because SDK adapter or aircraft not finish init or UART connect error.
[20.559][adapter]-[Info]-[DjiAccessAdapter_Init:215) Try identify UART0 connection failed. Probably because SDK adapter or aircraft not finish init or UART connect error.
[20.559][adapter]-[Error]-[DjiAccessAdapter_Init:220) Try identify UART0 connection timeout. Probably because SDK adapter or aircraft not finish init or UART connect error.
在第一块rk3568上跑demo大多情况都正常,也有5%左右的串口不识别。刚开始移植改板上时也识别不了,后来也没改啥串口又好了,后面也有5%左右的串口不识别。
在第二块上串口一直没识别(在/dev下有相应的ttyS8,我们板上对接e-port的串口),通串口工具测试改串口912600波特率收发都正常。
这个串口不识别的问题咋样解决,及咋样能稳定识别?软件和配置应该没问题。
