OMAP35x ISP JPEG_FLUSH

M.Hayashi
Prodigy 10 points

Hi all,

I want to receive large JPEG stream(1MByte) through the parallel Interface.
(as described in the TRM, Camera Interface Subsystem(ISP) 1.2.4.2 Parallel Generic Configuration: JPEG Sensor Connection on the Parallel Interface)

By setting the ISP_CTRL.JPEG_FLUSH bit, I can receive the JPEG stream less than 32kByte.
But the stream beyond 32kB is discarded.

$ hexdump jpegstream

I guess that it depends on CCDC_HORZ_INFO.NPH field. ( my setting is 0x7FFF currently )
How can I receive JPEG stream more than 32kB?
