CSI

hello
I would use a CSI camera on debian
then I activate the CSI script.fex

but when I load the module sun4i_csi0

he returns

Is the camera support built into the kernel you're using?

thank you for your reply

yes it's supported I tested with the OV7670 and gc0308
(gc0308 is the default config)
I wonder if I should load another module before

Seems like A13 ( sun5i ) hardware is lacking csi_isp clock.
At least kernel sources are written so.

sun4i_drv_csi.c fails because clock is not defined / none.

well ,i met the same problem just now . and fix it by commenting out lines of source code ,rebuild the driver.

[fero]

Which one did you comment out explsz ?

Did you manage to attach a camera to the A13-SOM?

Hi,
I've finally made the sensor init succesfully, but with little workaround. Followed by errors and commented out these lines of sun4i_drv_csi.c driver :

Code Select Expand

dev->csi_isp_src_clk=clk_get(NULL,"video_pll0");
if (dev->csi_isp_src_clk == NULL) {
        csi_err("get csi_isp source clk error!\n");
//return -1;
    }

  dev->csi_isp_clk=clk_get(NULL,"csi_isp");
if(dev->csi_isp_clk == NULL) {
        csi_err("get csi_isp clk error!\n");
//return -1;
    }

ret = clk_set_parent(dev->csi_isp_clk, dev->csi_isp_src_clk);
if (ret == -1) {
        csi_err(" csi_isp set parent failed \n");
   // return -1;
    }

clk_put(dev->csi_isp_src_clk);

  ret = clk_set_rate(dev->csi_isp_clk, CSI_ISP_RATE);
if (ret == -1) {
        csi_err("set csi_isp clock error\n");
// return -1;
    }
However the output still frames looks like crap :

Only one image seems to be fairly grabbed (but still without coloures), so maybe someone could know where and how should I try to solve this.

Edit: when I try

vlc v4l2:///dev/video0 I cannot get the stream output (via ssh -Y session). It shows only one frame, crashes and then i see only

[CSI_ERR] No active queue to serve in putty.

Maybe it's because of bad colour decoding by vlc, or driver?

Hello, fero!
Did you manage to read the data from ov7670 camera on A13 successfully?
I have the same issues with the csi clock and I am thinking about configuration of the csi interface by myself. Is there any simpler solution of this issue?

Hi,
Unfortunately I abandoned this topic and changed platform. Lack of time forced me :/
