Hi,

can you try to change the value of NULL_SRC_LINK_NUM_CHANNELS_DEFAULT in vision_sdk/links_fw/include/link_api/nullSrcLink.h

/*
* Validating the create params
* TODO: Extend to validate width, height and pitch params also
*/
/* Only one channel is supported as of now */
OSA_assert(pPrm->outQueInfo.numCh == 1U);
OSA_assert(pPrm->timerPeriodMilliSecs != 0);
/* No support for Network RX Mode */
OSA_assert(pPrm->dataRxMode == NULLSRC_LINK_DATA_RX_MODE_FILE);

it can't work.

thanks.

Hi,

if you use Linux on A15, core, than you can remove this assert and it should work, please check this thread:
