DM365 capture ISIF output to SDRAM

DM365 capture ISIF output to SDRAM

  • Hello,

    I have the LeopardBoard 365 and the VGA camera module. Using CCS 4.1 I am trying to capture some data (RAW) from the sensor (MT9V113) and store it in the external SDRAM. I configured the all the VPSS registers I consider crucial for this purpose (ISP, ISIF).

    As for the sensor, I can see all signals being present (PCLK, DATAn, VS, FS).

    Despite that, the data in the SDRAM location never gets overwritten. This makes me think the DMA, that transfers the 32bit data chunks from the VPSS to the SDRAM, never happens. -

    What am I missing? Do I have to enable this transfer (SYNCEN.DWEN = 1 already) elsewhere?

    Thank you for your help.

  • The VGA module has no data output until you program it. Did you also configure it? If not, please refer to the init function in the VGA driver, which is available on support page.

    I never used CCS to capture image. One thing I can think of to check is the VPFE interrupt bit. If everything is set up right, the interrupt should happen at the image sensor frame rate.
