How to attach MIPI CSI-2 camera to i.MX6S

kilsuhong · ‎05-20-2015

Dear,

I have been attaching camera ISP to our customized board based on i.MX6solo sabresd.

The camera ISP is connected to Freescale chipset with MIPI CSI-2, 2 lanes.

So, I modified some configurations like below,

===================================================================================

static struct fsl_mxc_capture_platform_data capture_data[] = {

{

.csi = 0,

.ipu = 0,

.mclk_source = 0,

.is_mipi = 1,

},

};

static struct mipi_csi2_platform_data mipi_csi2_pdata = {

.ipu_id = 0,

.csi_id = 0,

.v_channel = 0,

.lanes = 2,

.dphy_clk = "mipi_pllref_clk",

.pixel_clk = "emi_clk",

};

====================================================================================

after booting, I tried to execute mxc_v4l2_capture.out, but the error message was occurred

====================================================================================

root@freescale /unit_tests$ ./mxc_v4l2_capture.out -i 1 -d /dev/video0 -iw 1920 -ih 1080 -ow 1920 -oh 1080 -m 1

in_width = 1920, in_height = 1080[ioctl_g_ifparm] clock_curr=mclk=24000000

out_width = 1920, out_height = 1080

top = 0, left = 0
