Hi I am trying to get a camera to work together with an PXA270 processor. My system has the following specs: Platform: Gumstix Verdex Pro Camera: HV7131RP OS: Linux 2.6.28 I wrote a simple driver for the camera which omits all the i2c-stuff because the camera starts already in a default configuration which works fine for me. A V4L2-device is generated and everything looks fine. But when i start to capture, no data arrives BUT the Quick Capture Interface outputs a MCLK and the camera responds with a PCLK, LV and FV (and data of couse). For getting a bit closer to the origin of the problem I disabled DMA in pxa_camera.c and enabled all Interrupts in the CICR0 register. No interrupt is generated. Even by disabling DMA and IRQ and looking into CISR nothing happens. I checked all the CIF registers bitwise. The polarity of the LV and FV is correct, the alternate pin functions are correct, the interrupt bit is non-masked, the size of the pixel matrix is correct. I'm a bit desperate because at the moment I have no idea what to do next. I would be thankful for any hint.
