TDA4VH-Q1: CSI Instance Selection

Hi,

CSIRX instance id is configurable parameter in both CSIRX OpenVX node and CSIRX PDK driver. For the node, below high lighted parameter can be used to specify instance id. 

typedef struct
{
tivx_capture_inst_params_t instCfg[TIVX_CAPTURE_MAX_INST]; /*!< CSI2Rx Instance configuration */
uint32_t instId[TIVX_CAPTURE_MAX_INST]; /*!< CSI2Rx Instance Id, 0:CSIRx0 1:CSIRx0 */
uint32_t numInst; /*!< Number of instances in current capture node */
uint32_t numCh; /*!< Number of channels to be processed on current instance of Node */
uint32_t chVcNum[TIVX_CAPTURE_MAX_CH]; /*!< Virtual Channel Number for each channel */
uint32_t chInstMap[TIVX_CAPTURE_MAX_CH]; /*!< Instance ID for each channel */
uint32_t timeout; /*!< Total timeout (in ms) for all cameras. If this timeout is exceeded, cameras that have not been received are dead.
The timeout value will only be considered if calling the \ref tivxCaptureRegisterErrorFrame API to enable error detection */
uint32_t timeoutInitial; /*!< Initial failure timeout (in ms) for first time the capture node fails. Once this
timeout has been exceeded, the "timeout" parameter will then be used.
The timeout value will only be considered if calling the \ref tivxCaptureRegisterErrorFrame
API to enable error detection */
} tivx_capture_params_t;

Hi Brijesh,

Thanks for the quick reply.

CSIRX OpenVX node

Do you mean CaptureNode Configs, as seen below code snip?

Hi Berke,

Yes, using this parameter, you could change the CSIRX instance id.

1. I used 1 and 2 values for the instance id but I got Capture Node Error: Wrong instance! .

2. Also can you please support on the second question, see below?

Where is the Exact location for CSIRX PDK driver?

Hi Brijesh,

Could you please share the parameter name for that and how to modify it, so I could update it as well?

Thanks,

Berke

Hi Brijesh,

When I modify the chInstMap in accordance with the instId, the pipeline worked. Thanks a lot. 

    local_capture_config.instId[0]                       = 1;
    printf("\n\nInstance ID: %d \n\n", local_capture_config.instId[3]);

    local_capture_config.chInstMap[0] = 1;
    local_capture_config.chVcNum[0]   = obj->selectedCam%NUM_CAPT_CHANNELS;

Just to understand better, what is the purpose of this mapping parameter?
It is obvious that instId is the selection of csi instance but what do we need mapping for? 

Thanks,
Berke

Hi Brijesh,

Thanks for the details.
