Subject: testing soc_camera with mt9m001 on pxa270
Date: Fri, 28 Nov 2008 15:58:44 +0100 [thread overview]
Message-ID: <20081128145844.244860@gmx.net> (raw)
Hello,
I'm testing at the moment the capture interface with the soc-camera and mt9m001 driver.
I fixed all I2C routines to test without any connected camera like mt9m001, because we want to use another camera hardware as mt9m001.
To read out the capture buffer I use the example project capture.c from V4L2-API with mmap(). The ioctl (fd, VIDIOC_REQBUFS, &req) at the beginning of initialization fails. I have debuged the most important parts of the driver (pxa_camera, soc_camera and mt9m001) but I can't find the mistake.
Any Idea?
Here is a short log, which functions were called:
