1、引言：

随着计算需求的不断增长，硬件性能的提升变得至关重要，香橙派作为一款性能卓越的嵌入式开发板，其算力的提升对于用户来说意义非凡。本文将详细介绍如何通过官方提供的firmware包升级，将香橙派的算力提升至12T，以满足更高的计算需求。

2、升级步骤

下载firmware包：从香橙派官方网站下载官方工具中提供的firmware包。香橙派官方工具资料链接:

1. 首先将Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run上传到OPi AI Pro开发板的Linux系统中

2. 添加执行权限：

chmod +x Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run

3. 运行命令更新固件：

./Ascend310B-firmware-7.3.t10.0.b528-rc-signed-opiaipro-12t-1.6ghz-20240605.run --full

4. 输入小写的 y 确认开始更新

5. 更新完成后的打印输出如下所示：

6. 断电重启系统

7. 重启系统后使用下面的命令切换到12T的AI算力档位：

(base) root@orangepiaipro:~# npu-smi set -t nve-level -i 0 -c 0 -d 1
        Status                         : OK
        Message                        : The nve-level of the chip is set successfully.

8. 最后再次重启系统，如果使用下面的命令能看到aicore freq变为了750，说明切换到了12T的AI算力

(base) root@orangepiaipro:~# grep "aicore freq" /var/log/npu/slog/device-0/device-0*
[INFO] LPM(-1,null):1970-01-01-00:00:14.817000 [avs] [AvsProfileLimitUpdate 55] profile[1] aicore freq[750] cpu freq[1600] config done

3、算力提升效果

执行gitee样例YOLOV5VIDEO样例，升级前后进行对比

在进行升级之后每帧的处理时间提升了10ms左右
