海鸥派：/dev/svp_npu err

板端系统：Ubuntu22；

板端环境按照：https://gitee.com/hieulerpi/HiEuler_PI_ModelZoo 中的 docs/环境准备.md 安装搭建；

svp_nnn和nnn的所有lib均采用Euler Pi 2.0/06. 开发板源码编译/02.适配后的SDK源文件/SS928V100_SDK_V2.0.2.2/smp/a55_linux/mpp/out/lib中库文件；

opencv的lib从 https://gitee.com/HiSpark/modelzoo/tree/master/samples/opensource 目录下；将opencv/lib/aarch64_linux复制到 /opt/opencv/lib/aarch64_linux目录；

之后将下面内容添加到~/.bashrc 中：

# 定义 SDK 库根目录变量
export SS928V100_SDK_LIB_ROOT=/opt/SS928V100_SDK_V2.0.2.2/a55_linux/mpp/out/lib

# 设置动态库搜索路径
# npu 和 svp_npu 使用从PC端复制板端的；
export LD_LIBRARY_PATH=$SS928V100_SDK_LIB_ROOT/npu:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$SS928V100_SDK_LIB_ROOT/svp_npu:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$SS928V100_SDK_LIB_ROOT:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/opencv/lib/aarch64_linux:$LD_LIBRARY_PATH

# 设置 AI CPU Kernel 路径
export ASCEND_AICPU_KERNEL_PATH=$SS928V100_SDK_LIB_ROOT/npu

之后又按照文档修改了：/opt/ko/load_ss928v100；只修改了这部分，其余没有任何改动；

    # insmod $ko_path/ot_pqp.ko
    # ot_svp_npu.ko/ot_pqp.ko cannot be installed at the same time
    insmod svp_npu/ot_svp_npu.ko svp_npu_save_power=1 svp_npu_max_task_node_num=512

终端重启reboot；按键重启；都试过了，只要运行编译后的代码会出现：
