TDA4VM: How to use CSI1 interface to receive camera data ?

TDA4VM: Verify graph failed to set InstId[0] = 1 in RTOS 07_01 version.

Part Number: TDA4VM

Hi TI members:

In our customer board, we have two deserializer (UB962 and UB936).

we connect UB936 to TDA4 CSI instance 0, and connect UB962 to TDA4 CSI instance 1. 

In RTOS 07_00 version, we can receive CSI data form UB936 / UB962 successfully.

So we try to apply the same patch to RTOS 07_01 version,

and the UB936 related function work normal in RTOS 07_01 version.

But when we test UB962 related function, we meet below error message

   973.687200 s:  VX_ZONE_ERROR:[ownContextSendCmd:782] Command ack message returned failure cmd_status: -1
   973.687218 s:  VX_ZONE_ERROR:[ownContextSendCmd:818] tivxEventWait() failed.
   973.687224 s:  VX_ZONE_ERROR:[ownNodeKernelInit:526] Target kernel, TIVX_CMD_NODE_CREATE failed
   973.687229 s:  VX_ZONE_ERROR:[ownNodeKernelInit:527] Please be sure the target callbacks have been registered for this core
   973.687235 s:  VX_ZONE_ERROR:[ownNodeKernelInit:528] If the target callbacks have been registered, please ensure no errors are occurring within the create callback of this kernel
   973.687297 s:  VX_ZONE_ERROR:[ownGraphNodeKernelInit:583] kernel init for node 0, kernel com.ti.capture ... failed !!!
   973.687305 s:  VX_ZONE_ERROR:[vxVerifyGraph:2010] Node kernel init failed
   973.687310 s:  VX_ZONE_ERROR:[vxVerifyGraph:2064] Graph verify failed

And I find this error is caused by that I set capture_params.instId[0] = 1 in UB962's function.

Does anyone have any idea about this issue?

    Hi Chen,

    Can you please share your complete create parameters of the capture node?

    Hi Brijesh:

    Our UB962's complete create parameters should as below 

    capture_params.numInst = 1;
capture_params.numCh   = 1;
capture_params.instId[0] = 1;
capture_params.instCfg[0].enableCsiv2p0Support = (uint32_t)vx_true_e;
capture_params.instCfg[0].numDataLanes         = 4;
capture_params.instCfg[0].dataLanesMap[0] = 1;
capture_params.instCfg[0].dataLanesMap[1] = 2;
capture_params.instCfg[0].dataLanesMap[2] = 3;
capture_params.instCfg[0].dataLanesMap[3] = 4;
capture_params.chVcNum[0]   = 0;
capture_params.chInstMap[0] = 0;

    Hi Brijesh:

    I find if I change the capture_params.chInstMap[0]  value then I can pass the graph verify.

    capture_params.numInst = 1;
capture_params.numCh   = 1;
capture_params.instId[0] = 1;
capture_params.instCfg[0].enableCsiv2p0Support = (uint32_t)vx_true_e;
capture_params.instCfg[0].numDataLanes         = 4;
capture_params.instCfg[0].dataLanesMap[0] = 1;
capture_params.instCfg[0].dataLanesMap[1] = 2;
capture_params.instCfg[0].dataLanesMap[2] = 3;
capture_params.instCfg[0].dataLanesMap[3] = 4;
capture_params.chVcNum[0]   = 0;
capture_params.chInstMap[0] = 1;

    and I can get CSI Data for UB962 successfully.

    BR

    Hi Chen,

    chInstMap maps channel number to the instance id, since you are using single instance (numInst = 1) with instance id as (instId[0] = 1), you should set this map to 1.
