How to use the example/pm/classical project? I found there are hcpu and lcpu.

How should I compile and flash this?

You can compile using the terminal or use the plugin for one-click compilation. The plugin automatically recognizes the environment; see:

Start Project | SiFli-SDK-CodeKit
Build Project | SiFli-SDK-CodeKit

Compile using the terminal under project/hcpu:

# Compile
socns --board=sf32lb52-lchspi-ulp -j8

# Download - Enter the port number as prompted
build_sf32lb52-lchspi-ulp_hcpu/uart_download.bat

Hello, this project contains hcpu and lcpu. If I want to compile hcpu, I have to go into the hcpu folder to compile and flash it. But lcpu has no flashing or compilation. What should I do?

Compiling under HCPU will automatically include lcpu in the build.

Thank you so much, I get it now. Thanks, master.
