Hi,
We are trying to make DM37's ISP get YUV data into memory via the parallel interface. We are using Linux PSP 03.00.01.06. All our attempts to utilize existing "omap34xxcam.c" driver failed and we need some help:
1. Who is the maintainer of the omap34xxcam.c from the TI and is it possible to contact that person?
2. Existing code inside the omap34xxcam.c constantly fails for us due to inability to detect NON-BUSY state of the CCDC module. Is there any documentation/details on when CCDC module becomes non-busy? Documentation states that it becomes non-busy after receiving a frame but that doesn't work in our case.
What set of external and internal ISP conditions which make CCDC go idle? (Lines in particular state, registers with particular values?)
3. Is there any specific timing requirements for HS and VS external incoming signals to integrate properly with the ISP in the parallel mode.
4. Was omap34xxcam.c tested for the YUV sync mode?
5. Does TI has additional documentation about the ISP except the technical reference manual?
Thank you for any help and directions,
Eugene
