I mean "==". coda.h contains: #define CODA7_STREAM_BUF_PIC_RESET (1 << 4) #define CODA7_STREAM_BUF_PIC_FLUSH (1 << 3) So maybe those are the correct bits for i.MX27 with the 2.2.5 firmware. If that is the case, you could do s/CODA7_STREAM_BUF_/CODA_STREAM_BUF_/ and drop the incorrect CODADX6_STREAM_BUF_ defines. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
