Questions about booting

Hi Sanjeev,

To display DLP logo image during booting period, I stored logo image and patterns in order.

The display is OK in this way, but the DisplayPatternAutoStepRepeatForMultiplePasses command is executed after boot.

What I am trying keep showing logo image after that .

So, I attached DisplayPatternManualForceFirstPattern command in last line in BuildBatchFile.bf and converted it to bin file and wrote it to flash memory.

Now, the system shows checker board image at first and all patterns I download in the flash are disappeared.

What am I doing wrong ?

Regards.

YJ Han.

    Hello YJ Han,

    The only reason i see checker board image is that the newly created flash image with DisplayPatternManualForceFirstPattern command is not proper, appending new command at the end not helping. What is the return error code from the DLP_Status_GetInitFromParallelFlashFail API?

    By default when the flash image is created without even calling the display APIs it will always be in DisplayPatternAutoStepRepeatForMultiplePasses mode. Now user is expected to call other APIs as needed once the system is configured.

    I think a better option would be to create a seperate solution with just Logo image in it. Keep it as default solution. Now have another regular solution with images. So during the power-on the LOGO image is displayed, this image remains until you send another LoadSolution command.

    Regards,
