DM368 CMEM错误



你好,请教一下。

现在程序运行后视频采集不到数据,报错打印信息:

CMEMK   Error :get_phys:Unable  to  find  phys  addr  for  0x40cc2000

CMEMK   Error :get_phys:get_user_pages()  failed:-14

CMEMK   Error :GETPHYS:Failed to convert  virtual  0x40cc2000 to physical

CMEMK   Error :get_phys:Failed to get physical address of 0x40cc2000 .

应该是哪方面配置有问题呢?
