Hello ISP team, I succeeded to stream the first images from the sensor to userspace using Laurent's media-ctl and yafta. Unfortunately all images are black (10MB of zeros). Once by chance I streamed some images (1 of 20 about) with content. All values were < 0x400, so that I assume the values were correctly transferred for my 10-bit pixels. I shortly describe my setup: As I need xclk_a activated for my sensor to work (I2C), I activate the xclk in the isp_probe function. Early hack that I want to remove later. While I placed my activation in mid of the probe function, I had somehow the interrupts disabled when trying to stream using yafta. So I hacked in the reenabling of the interrupts somewhere else in probe() too. As I dug through the isp code I saw that it is better to place the clock activation after the final isp_put in probe() then the interrupts keep working, but this way I never got a valid picture so far. It's all a mess, I know. I try to transfer the activation to my sensor code and board-setup code like in the et8ek8 code. However... please help me get rid of these zeros! I keep reading through the ISP and the mt9p031 docs to find some settings that could have influence on the data sampling. The sensor is working fine now, so the solution should be somewhere within the isp.
