思元220模块驱动加载失败 WangQ2021-09-15 10:49:32 回复 4 查看 使用求助
思元220模块驱动加载失败
分享到:

HI大家好:

     我们正在测试思元220边缘加速卡,2021年1月份时借用过贵公司的模块(没有配备散热片),那时候可以成功加载驱动,并且测试了yolo4 demo,

由于散热没有解决好,导致帧率只有4帧左右。

     现在我们已经解决散热问题,因此从贵公司重新借了一块思元220边缘加速卡,在加载驱动时会报错,以下是报错信息:

root@debian:~/neuware-mlu220m.2-driver-aarch64-4.4.6# ./load_auto 

TO insmod module cambricon.

测试环境如下:

     板卡主芯片是飞腾FT2004,arm64架构

     操作系统为Debian 10.07

     Linux内核版本4.19.115

     模块驱动版本为neuware-mlu220m.2-driver-aarch64-4.4.6,使用源码编译并且加载驱动

请帮忙分析一下问题

非常感谢
