jtag硬件以上层次的软件都放在本目录下, 包括jtag驱动, DTM驱动, 控制平面访问等. 目录组织类似AM, 分3部分:

• platform/ - 包括平台相关的代码, 如jtag访问方式, 平台初始化等工作. 目前平台包括emu和fpga, 其中emu用于仿真, fpga用于上板
• apps/ - 平台无关的应用
• common/ - 平台无关但可以被apps共享的代码

注意:

• 将本目录拷贝到ARM核上编译, 即可得到ARM上运行的可执行文件
• 关于DTM, jtag等模块的关系, 请查阅riscv debug specification

This directory contains functions above the jtag hardware, including jtag driver, DTM driver, control plane accessing.

• platform/ - platform-dependent code, including jtag accessing, platform initialization. Currently, there are two platforms. emu is used for running over emulation, and fpga is used for running over FPGA
• apps/ - platform-independent applications
• common/ - platform-independent codes shared by apps

NOTE:

• Copying this directory to the ARM system and compile will get the ARM executables
• For details about the relationship between DTM and jtag, please refer to riscv debug specification

Compile

在apps/xxx目录下运行make, 默认将程序编译到emu平台, 编译结果位于apps/xxx/build/xxx-emu. 可以通过make PLATFORM=fpga将程序编译到fpga-zynqmp平台. 若使用zynq的FPGA, 需要手动指定BOARD参数: make PLATFORM=fpga BOARD=zynq.

Running make under apps/[app name]/ will compile the application to emu platform by default. Executable will be generated as apps/[app name]/build/[app name]-emu. To compile the application to zynqmp FPGA platform, run make PLATFORM=fpga under the application directory. If you use a zynq FPGA, a BOARD argument should be specified: make PLATFORM=fpga BOARD=zynq.
