Hi All.
I am new to CX3 RDK to make MIPI to USB device using ov5640.
I am trying to interface ov5640 with CX3 chip.
After imported the demo project of cycx_uvc_ov5640, I succeeded on compilation and running from RAM.
And the CX3 device could be detected as the camera device named as "cx3-uvc" in Windows Device Manager List.
However the camera preview does not work since the error comes from the below code. CyU3PMipicsiGpifLoad().
/* Configure the Fixed Function GPIF on the CX3 to use a 16 bit bus, and
* a DMA Buffer of size CX3_APP_DATA_BUF_SIZE
*/
status = CyU3PMipicsiGpifLoad(CY_U3P_MIPICSI_BUS_16, CX3_APP_DATA_BUF_SIZE);
if (status != CY_U3P_SUCCESS)
{
CyU3PDebugPrint (4, "\n\rAppInit:MipicsiGpifLoad Err = 0x%x", status);
CyCx3AppErrorHandler(status);
}
The function returns the 0x46. (e.g. AppInit:MipicsiGpifLoad Err = 0x46).
0x46 means that the operation requested is not supported in current mode.
I don't know why it comes out.
Could anyone help me to figure out this problem?
I am using Denebola RDK board with OV5640 sensor.
Thanks
Best Regards,
JK Cha
