Other Parts Discussed in Thread: TDA4VL
Tool/software:
I'm using customed board based tda4vl and my image sensor is customed imx390
And my sdk version is 09_02_00
I want to run a singlecam example by connecting this camera directly without serdes
A sensor init error occurred at first, but when the sensor setting value was set correctly, the error disappeared and the singlecam example worked without error
However, nothing appears on the display, and when I capture the raw image and check the image, only three lines of red appear like attached image
static IssSensor_CreateParams IMX390CCreatePrms = {
IMX390C_RAW12, /*sensor name*/
0x1, /*i2cInstId*/
{0x21, 0x21, 0x21, 0x21, 0x21, 0x21, 0x21, 0x21}, /*i2cAddrSensor*/
{0, 0, 0, 0, 0, 0, 0, 0}, /*i2cAddrSer*/

This is my camera setting
In this case, my question is
1. Can i check if the data captured by the camera is coming over well
- i think i can check it 'vxGraphParameterEnqueueReadyRef(obj->graph, 0, (vx_reference*)&(obj->cap_frames[buf_id]), 1);' this part
But how do i check if the data is valid
2. If the camera doesn't give you normal data, how do I solve it
3. Can i put 12 bits of raw data directly into the display without viss or ldc during the graph generation process
- How can i convert tivx_raw_image to vx_image
I changed the camera settings just in case, but I kept getting the same result or sensor initialization failed. Thank you for reading the article and I'll wait for your help.
