请问一下am3359的pru 串口如何使用，我用的SDK是ti-processor-sdk-linux-am335x-evm-06.01.00.08 ，按照sdk参考文档我配置了设备树使能了内核驱动，还需做那些配置才能正常使用pru uart
除了设置设备树，内核也需要配置一下，请参考下面的说明。PRU Soft UART driver Kernel Confighttps://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/pru-sw-uart.html
好的谢谢，除了设备树和内核配置还需要pru 串口固件吗
需要PRU firmware的，关于固件的介绍，请看下面的网站。https://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/PRU_ICSS.html#pru-icss-uart
需要下载RTOS的sdk吗
需要，PRU firmware在RTOS SDK里。
好的谢谢
不客气~
