Hi, I have news on the "IRQ storm on second streamon" problem. Reminder : Given a perfectly fine HSYNC / VSYNC / PIXELCLOK configuration, the omap3-isp (at least until 3.4) will go into an interrupt storm when streamon is called for the second time, unless you are able to stop the sensor when not

Hi, I have a custom dm3730 board, running a 3.2.0 kernel. The board is equipped with an aptina MT9J sensor on parallel interface. Whenever I try to run yavta twice, the second run leads to a soft lockup in omap3isp_video_queue_streamon (see below) What can I do / test to debug this issue ? # g
