Beaglebone黑色，带DLP2000EVM

Question

我试着用Beaglebone black和DLP2000EVM播放视频。在

我可以通过启用I2c手动播放视频，但当我尝试使用python脚本播放时，会遇到这样的错误

debian@beaglebone:/opt/scripts/device/bone/capes/DLPDLCR2000$ python MplayerTest.py Traceback (most recent call last): File "MplayerTest.py", line 89, in main() File "MplayerTest.py", line 59, in main datalog = DataLog(LogDir, Test_name) File "build/bdist.linux-armv7l/egg/dlp_lightcrafter/datalog.py", line 77, in init IOError: [Errno 13] Permission denied: '0524/tmp_header_Video Play Test__Tue__Nov_14_2017__11_19_37__.xls'

系统似乎不允许写入数据日志文件。在

任何人，请帮我解决这个问题。在
