Before You Start
- If you install the NPU driver on a training card with an Ascend 910 Pro B Processor for the first time, install 20.2.0.spc300 or later. The NPU firmware version must match the driver version. The NPU firmware and driver cannot be rolled back to 20.2.0.spc200 or earlier.
- Log in to the host and run the npu-smi info command to query the NPU name.
To query the NPU name using iBMC, log in to the iBMC WebUI and choose System > System Info > Others > PCIe Cards to view NPU model information.
- The MCU firmware cannot be installed or uninstalled. For details about how to upgrade the preset firmware, see Upgrading the MCU.
