TDA4VM: ltp-ddt中测试用例usb_perf_raw和usb_stress_io这两个测试用例不通过

Part Number: TDA4VM


SDK: ti-processor-sdk-linux-j7-evm-08_06_01_02

执行命令:./runltp -P j721e-evm -f ddt/usb_perf_raw

报错打印如下:

单独执行testusb.c生成的可执行文件testusb
执行命令:./testusb -D /dev/sda1

报错打印:

ioctl(fd,USBDEVFS_IOCTL,&wrapper)返回值小于0

疑问:ioctl命令是否支持USBDEVFS_IOCTL参数操作?
