Hi ALL, I meet a problem when developing scan device (such as a camera) driver on OMAP3 platform (my MPU is AM3715). The scan application may change the scan hardware settings (such as exposure time), and try to find out the best one. But sometimes, after applied the new settings, the scan hardware may did not output data, so the application blocked. Since i can't modify the application, the driver should notify this event to app. So my question is that, can the driver query the ISP DMA status such as how many bytes the DMA has transferred?
