问题描述：rk1808M0通过USB插在rk3399（飞凌嵌入式ok3399）上，通过被动模式调用rk1808M0计算棒npu算力，使用以下代码、sdk和api，运行如下，发现无法检测到NPU设备。

附件六：ssh toybrick@192.168.10.8 能够登录。

求指条明路：
1、想知道这种方案能否实现？
2、以上报错有何解决方案？
3、如果该方案可以实现，要用那个版本的C++ API?

有人吗

行的，我试试，谢谢！

跑c版本的话，你上位机有个rknn_transfer没运行，网卡模式是用于主动模式的，主动模式通讯靠自己写socket或者ntb，你跑的sample却是被动模式的，走ntb的。
建议你先把wiki和文档通读一遍。

首先感谢您的回答，想问下ntb全称是什么呀？
