大家好,
在调试uartEcho_edma例程时,想请问:
1. uart0_Tx/Rx为何分别对应的tccNum和chNum是26/27 ? 根据什么来定义的?
Uart1、uart2对应的tccNum和chNum是多少?edma_event.h里没有找到
2. 若三个uart ,e.g. Uart0/1/2都使能DMA传输是否会有冲突,需要注意哪些?
还请指点。
谢谢!
你好!请参考AM335X TRM的11.3.20 EDMA Events章节
Uart0 direct mapped 收发对应27/26, OK.
若要使用Uart4 crossbar mapped对应10/9 如何使用呢?
