Hi there, i just recently ran into a problem when trying to let the ISP (OMAP3530) generate HS/VS signals in SYNC mode. I am building a module to do so. It basically enables the three clocks (cam_ick, cam_mclk and csi2_96m_fck), then sets ISPCCDC_PIX_LINES_PPLN ISPCCDC_PIX_LINES_HLPRF ISPCCDC_HD_VD_WID_VDW ISPCCDC_HD_VD_WID_HDW ISPCCDC_SYN_MODE_VDHDEN ISPCCDC_SYN_MODE_VDHDOUT ISPCCDC_CFG_VDLC ISPTCTRL_CTRL_DIVA ISPTCTRL_CTRL_DIVB ISPCCDC_PCR via some calls to ioremap and ioread32/iowrite32. My question now is the following: when i hook an oscilloscope to the corresponding pins (CAM_VS, CAM_HS, CAM_XCLKA) i can see that only the CAM_XCLKA is working correctly, also at the configured frequency. Both, CAM_VS and CAM_HS remain at low voltage all the time, even when i switch their polarities (ISPCCDC_SYN_MODE_VDPOL, ISPCCDC_SYN_MODE_HDPOL) that behavior does not change and signals always remain at low voltage. Could someone help me out, or give me a hint what i might be missing to generate those output signals correctly?
