CCDC Output to RAM to capture the raw data before IPIPE

Stefan Gachter

Can somebody point me to an example how to write the raw data from the CCDC directly to the memory and then to a file? I would like know the raw image data (Bayer pattern from the imager) but without channelling them through IPIPE for debugging purposes.

I studied the examples and tried configure the DM355 with VPFE_CMD_CONFIG_CCDC_RAW and V4L2_PIX_FMT_SBGGR8 to obtain the raw data. I also tried to configure IPIPE accordingly to get the raw data (RAW2RAW), but I do not get the raw data that I expect from the sensor. So, I am still confused and would like to have some clarification by an example.

Thanks for any hint,

Stefan
