Zynq-Linux移植学习笔记之39-解决Linux下读写ZYNQ PS GPIO失败

1、背景介绍最近调试的模块中使用PSGPIO模拟I2C进行I2C数据接收,在把standalone程序移植到应用程序下后,发现在mmap映射后读取PSGPIO物理地址寄存器空间(0xE000A000-0Xe000b000)返回值均为0,用devmem应用程序跑了一下,发现无法写入。2、解决方法在xilinx论坛上查到了解决办法,如下:上面提到由于新内核中启用了电源...

Zynq-Linux移植学习笔记之38-通过PCIE访问EP节点MEM空间

1、背景介绍近期在调试信大刚推出的一款交换芯片,简称SDI芯片。该芯片可通过i2c,srio,pcie三种方式进行配置,前期i2c和srio已经调试成功,剩下使用pcie进行配置。在demo板上zynq通过pcieIP核与sdi芯片相连,其中pcieIP核做Root,SDI做EP,vivado示例如下:IP核中分配了BAR0进行PCIEMEM空间映射,如下:在addr...

Zynq-Linux移植学习笔记之37-SDI芯片I2C驱动

最近参与了SDI芯片的驱动开发设计,其中有一个需求是通过i2c读写SDI芯片寄存器。由于之前做过DBF芯片的I2C驱动,对怎样根据不同的芯片I2C访问协议修改驱动比较熟悉,所以开发起来不是很难。原厂提供了SDI芯片在Linux用户应用程序中通过I2C访问寄存器的代码,如下:#include<sys/types.h>#include<sys/stat.h>...
