TDA2P-ABZ: NullSrc file system question in case of TDA2P RTOS .

Part Number: TDA2P-ABZ

 I have a question for your about NullSrc input file in order to display Welcome Logo.

We are using the TDA2P RTOS QSPI Memory , So we would like to use below the several file ( INPUT.h264 , INPUT.hdr ) .

But As you know , we apply TI RTOS without supported file system.

In case of using TI RTOS(QSPI Nor flash memory), How to control this files (INPUT.h264 , INPUT.hdr )

Can you give us information How to control this way (memory access or ramdisk in the RTOS) ?

pChInfo->width = NULLSRC_OUT_WIDTH;

pChInfo->height = NULLSRC_OUT_HEIGHT;

pChInfo->startX = 0;

pChInfo->startY = 0;

pChInfo->pitch[0] = SystemUtils_align(pChInfo->width, 32U);

pChInfo->pitch[1] = SystemUtils_align(pChInfo->width, 32U);

pNullSrcPrm->channelParams[0].fileReadMode = NULLSRC_LINK_FILEREAD_RUN_TIME;

strncpy(pNullSrcPrm->channelParams[0].nameDataFile, "INPUT.h264", 260);

strncpy(pNullSrcPrm->channelParams[0].nameIndexFile, "INPUT.hdr", 260);

pNullSrcPrm->dataRxMode = NULLSRC_LINK_DATA_RX_MODE_FILE;

  • Well, vision sdk does support reading from QSPI memory and there are several utility APIs in vision sdk to read from QSPI, but i really doubt it is supported in the null source. You would have to update null src link to read both the files from the given QSPI offset, using these utility APIs.
