解决办法：

1.安装驱动；

2.适配*.so动态库文件

问题二：

make[1]:离开目录“/usr/src/linux-headers-4.19.0-loongson-3-desktop”

make:***[Makefile:：all]错误2

解决办法：

1.修改bm_clkrst.h文件

root

artc-PC:/usr/src/linux-headers-4.19.0-loongson-3-desktop/arch/mips/include/asm#cd/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm/

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm#pwd

/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm#

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm#

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm#vimbm_clkrst.h

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver/bm#

2.修改结构体

4typedefenum{

MODULE_CDMA=0,

MODULE_GDMA=1,

MODULE_TPU=2,

MODULE_SMMU=3,

MODULE_SRAM=4,

MODULE_END_MIPS=5

}MODULE_ID;

问题三：系统版本不兼容

./arch/mips/include/asm/uaccess.h:Infunction‘eva_kernel_access’:

./arch/mips/include/asm/uaccess.h:91:9:error:implicitdeclarationoffunction‘uaccess_kernel’;didyoumean‘rcu_access_pointer’?[-Werror=implicit-function-declaration]

returnuaccess_kernel();

^~~~~~~~~~~~~~

make[1]:***[Makefile:：_module_/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver]错误2

make[1]:离开目录“/usr/src/linux-headers-4.19.0-loongson-3-desktop”

make:***[Makefile:：all]错误2

解决：

1.先找到文件在系统的位置

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/driver#cd/

root

artc-PC:/#find.-nameuaccess.h

find:‘./run/user//gvfs’:权限不够

./usr/src/linux-headers-4.19.0-loongson-3-desktop/include/asm-generic/uaccess.h

./usr/src/linux-headers-4.19.0-loongson-3-desktop/include/linux/uaccess.h

./usr/src/linux-headers-4.19.0-loongson-3-desktop/arch/mips/include/asm/uaccess.h

2.修改函数eva_kernel_access

staticinlinebooleva_kernel_access(void)

{

if(!IS_ENABLED(CONFIG_EVA))

returnfalse;

//returnuaccess_kernel();//deletebyluoyuchao

}

四安装ko文件

1.显示库文件

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86#ls

bmsophon.kodriver

2.查格式

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86#filebmsophon.ko

bmsophon.ko:ELF64-bitLSBrelocatable,MIPS,MIPS64rel2version1(SYSV),BuildID[sha1]=c00d6f3ba48eebbfcd75a3fda3d1cba,withdebug_info,notstripped

root

artc-PC:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86#modinfobmsophon.ko

filename:/home/artc/bitmain/bmnnsdk2-bm_v2.2.0/driver/mips/x86/bmsophon.ko
