I tried mapping GPIO_I2S_BCK to my only free GPIO and I2S then worked as intended. Something that tells me that JTAG is NOT turned off is that when I, initially, connected the new GPIO_I2S_BCK to GPIO41 and the trace to the codec, the board went nuts. I had to cut the trace so...

GPIO:通用输入输出口(general-purpose I/O port),是个比较重要的概念,用户可以通过GPIO口和硬件进行数据交互(如UART),控制硬件工作(如LED、蜂鸣器等),读取硬件的工作状态信号(如中断信号)等。GPIO口的使用非常广泛。通俗地说,就是一些引脚,可以通过它们输出高低电平或者通过它们读入引脚的状态-是高电平或是...

41_ZYNQ7020开发板Vivado操作_GPIO 在PS侧,有PS自己的IO pin,称为MIO,共有54个(编号0-53)。如果PS侧IO不够使用,则可以通过扩展的方式来使用PL侧的IO。扩展方式有两中:EMIO和GPIO。 EMIO 方式可以将PL侧IO直接看作PS侧IO使用,只是编号从54-117. 而GPIO则没有数量限制。直接挂到AXI总线上就可以。
