Elliot Martin A. 2完整实现过程)(二十一) 上一个实验用PL端的资源开发CustomIPcore的,并且在裸跑的程序中调用了这个IPcore,现在我们需要为这个Ipcore开发Linux系统上的设备驱动。. The following few pages will introduce you to programming the GPIO on the Raspberry Pi using command-line tools, shell and C programs. 当初Xilinx技术支持忽悠我用ZYNQ的时候这双核就是其中一条广告词,可回想起来在Standalone下面我还真没好好用过双核所以在这里跟大家分享一下在Standalone下面如何搭建AMP分几个阶段进行,从最简单的做起。. Windows環境は1回目を参照。 PLのAXI GPIOでPSからLチカ ややこしいタイトルです。前回は、PSのGPIOをPSのCPUから制御しました。今回は、PLのGPIOをPSのCPUから制御して、LEDをチカチカさせます。PL. 实验部分在下一篇博客中叙述。.
