根据文档里面提示,确认我手上的rk3399pro开发板是pcie模式,全局搜索npu_fw目录,发现在/usr/share下面有三个类似目录,分别是
npu_fw、npu_fw_pcie、npu_fw_pcie_optimization,这种情况应该更新哪个目录下的固件?

备注:
这边是一年前刷的rk3399pro官方的ubuntu18.04的操作系统

官方并没有对外提供ubuntu18.04操作系统的固件。官方的固件,不管是pcie,还是usb,npu固件应该都是放在npu_fw目录下。你可以试下把其中某一个文件夹改个名字,以确认当前系统是使用哪个目录作为npu固件存放的目录。最好还是找板子的生成厂商确认。
