开发板 milkv-duo 编译脚本如下

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR riscv64)

if(DEFINED ENV{RISCV_ROOT_PATH})
    file(TO_CMAKE_PATH $ENV{RISCV_ROOT_PATH} RISCV_ROOT_PATH)
else()
    message(FATAL_ERROR "RISCV_ROOT_PATH env must be defined")
endif()

set(RISCV_ROOT_PATH ${RISCV_ROOT_PATH} CACHE STRING "root path to riscv toolchain")

set(CMAKE_C_COMPILER "${RISCV_ROOT_PATH}/bin/riscv64-unknown-linux-musl-gcc")
set(CMAKE_CXX_COMPILER "${RISCV_ROOT_PATH}/bin/riscv64-unknown-linux-musl-g++")

set(CMAKE_FIND_ROOT_PATH "${RISCV_ROOT_PATH}/riscv64-unknown-linux-musl")

if(NOT CMAKE_FIND_ROOT_PATH_MODE_PROGRAM)
    set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
endif()
if(NOT CMAKE_FIND_ROOT_PATH_MODE_LIBRARY)
    set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
endif()
if(NOT CMAKE_FIND_ROOT_PATH_MODE_INCLUDE)
    set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
endif()
if(NOT CMAKE_FIND_ROOT_PATH_MODE_PACKAGE)
    set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)
endif()

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -mcpu=c906 -march=rv64imafdcv0p7xthead ")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mcpu=c906 -march=rv64imafdcv0p7xthead ")

# cache flags
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS}" CACHE STRING "c flags")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}" CACHE STRING "c++ flags")
add_compile_definitions(C906)

如果不打开模型配置文件好像又可以运行

syscall error -1
loop_count = 4
num_threads = 1
powersave = 0
gpu_device = -1
cooling_down = 1
fopen squeezenet.param failed
network graph not ready
          squeezenet  min =    0.01  max =    0.02  avg =    0.02
fopen squeezenet_int8.param failed
network graph not ready

请nihui大佬指教

syscall error -1 是绑定核心失败，可以无视

Illegal instruction 是编译参数有问题，cmake toolchain 用 https://github.com/Tencent/ncnn/blob/master/toolchains/c906-v240.toolchain.cmake
