@whycan 是不是CTS引脚接到RS485芯片的使能控制端？

请问是不是CTS引脚接到RS485芯片的使能控制端？

D1s看485看驱动没配置gpio（控制流控引脚）配置，有没有新驱动更新？上哪里获取？

spi1用的是屏的接口 PD那组

linux-5.4/drivers/net/can/spi/mcp251x.c 驱动上，在spi发送数据上卡死。

有没有人遇到解决过?

@xiaowenge 接的啊，养家糊口，来来来

@memory RTL8305NB-CG

不带GPU，添加QT5支持
将压缩包文件tina_add_qt覆盖掉SDK的package下的相应名称目录
1-make distlean
2-make menuconfig
（1）讲libgpu的相关选项全部关闭
（2）勾选libdbus或者覆盖QT5的makefile的depend加上libbus
3-mp

然后就填坑

tina_add_qt(1).rar

调试验证成功了

1：把gmac驱动选上，make kernel_menuconfig -> Device Drivers -> Network device support -> Ethernet driver support 目录下的Allwinner GMAC support和Use extern phy
把make kernel_menuconfig -> Device Drivers -> Network device support的PHY Device support and infrastructure也选上
2：修改tina-f133/device/config/chips/f133/configs/evb1/linux-5.4/board.dts
