I use video_preview project to test custom board of DM648.
When the program runs to
"disChan = FVID_create("/VP1DISPLAY/THS8200", IOM_OUTPUT, /* VP1, External Encoder 0 */
&status, (Ptr)&vDisParamsChan, NULL);"
the value of 'status' becomes -1, which indicates that creating display channel fails.
I check the VP1 registers,and find that parameters in DisParamsChan can't write into the corresponding registers.
The setting of PINMUX is correct, and the capture process is OK.
