Dear Support :

I tryed nand flash boot use colorbar program. It's work fine. [ perl version 5.14.2 ]

Same steps try to use video_preview, but fail.

Check BOOTCMPLT reg (0x01c4000c) got ERR_BAD_CRC error value.( 0x4 )

Try disable CRC Check :

genAIS.pl -i video_preview.out -o video_preview.bin -otype bin -bootmode nand -crc 0

write image to NAND flash and reboot target board. but cannot bootup. BOOTCMPLT reg is 0x0.

try to :

1. open CCSv3.3

2. only load gel file (evmdm6437.gel) in CCS and connect to target

3. Click Debug menu "Run Free"(Ctrl+F5) and "Reset CPU"(Ctrl+R) button.

4. video_preview start run on target board.

Please give me suggestion.

Thanks.

What about the size of "colorbar_program.bin" and "video_preview.bin" ?

try to :

1. open CCSv3.3

2. only load gel file (evmdm6437.gel) in CCS and connect to target

3. Click Debug menu "Run Free"(Ctrl+F5) and "Reset CPU"(Ctrl+R) button.

4. video_preview start run on target board.

You mean that you were able to run the video preview code through CCS but not with NAND booting.

Hi Titus S.

1. colorbar.bin size of 34KB, and video_preview.bin 135KB.

2. Yes, It's looks like BOOTROM(RBL) load program form NAND flash work done. but not start App. ( main function i added EVMDM6437_init() )

Thanks.
