AM335X是基于Cortex-A8内核的，Am335x自身是不带时钟计数寄存器的，但Cortex-A8有这个寄存器，但需要汇编代码才能读取，本代码中，是使用GCC编译环境的c语言代码内嵌汇编，如果是keil环境的话对汇编的调用可能要稍作修改，很多东西我也不懂，有需求的话自行修改吧。该寄存器值可以作为一个随机数来用，代码里面附有使用说明。并附上Cortex-A8 Technical Reference Manual（Cortex-A8技术参考手册），如有更好的方式，可以私信交流。-AM335X is based on the Cortex-A8 core, Am335x itself without the clock count register, but Cortex-A8 have this register, but need to compile the code to read the code, using the GCC compiler environment c language code embedded compilation, if the environment is keil then you may want to call to the compilation of minor modifications, a lot of things I do not know, if there is a demand to amend its own right. The register values ​ ​ can be used as a random number with the code inside with instructions for use.
