软件升级
从 https://blog.csdn.net/sinat_37322535/article/details/113867789 可以看到是直接通过 apt 安装的驱动，猜测 apt 源里面有 firefly 相关的链接，一查果然有，直接升级：
sudo apt install firefly-rk3588npu-driver
sudo apt install fireflydev也可以直接使用在 https://github.com/airockchip/rknn-toolkit2/tree/v2.3.0/rknpu2/runtime/Linux 中下载相关的库和头文件，替换后就能直接升级到 2.3.0
升级到 2.3.0 的问题
升级过程：

后面在给板端发送推理请求的时候，虽然正常推理了，但是会报错：

测试的模型
模型生成配置
模型生成阶段可以考虑，配置config，比如 single_core_mode来对比
