TDA4VM: What's the max number of vpac ldc node can be created in same context and graph?

Part Number: TDA4VM

Hi,

I am trying to use ldc node to do image remap, we have five cameras's image need to remap with different mesh table. I'm sure that I can create only one ldc node correctly and pass verify graph phase, however after I duplicate this operation to five ldc nodes with same configuration then it failed at verifyGraph as:

    46.768643 s:  VX_ZONE_ERROR:[ownContextSendCmd:782] Command ack message returned failure cmd_status: -7
    46.768665 s:  VX_ZONE_ERROR:[ownContextSendCmd:818] tivxEventWait() failed.
    46.768686 s:  VX_ZONE_ERROR:[ownNodeKernelInit:538] Target kernel, TIVX_CMD_NODE_CREATE failed for node node_438
    46.768703 s:  VX_ZONE_ERROR:[ownNodeKernelInit:539] Please be sure the target callbacks have been registered for this core
    46.768718 s:  VX_ZONE_ERROR:[ownNodeKernelInit:540] If the target callbacks have been registered, please ensure no errors are occurring within the create callback of this kernel
    46.768820 s:  VX_ZONE_ERROR:[ownGraphNodeKernelInit:583] kernel init for node 6, kernel com.ti.hwa.vpac_ldc ... failed !!!
    46.768845 s:  VX_ZONE_ERROR:[vxVerifyGraph:2044] Node kernel init failed
    46.768866 s:  VX_ZONE_ERROR:[vxVerifyGraph:2098] Graph verify failed

After several trial, I can create four ldc node successfully, once I increase it to five it failed, so I want to know how many ldc nodes at maximum supported in tda4, or is there any other reason lead to such failure?

Thanks!
