can not run the demo videos on dm365



Hi, all!

I'm working with dm365. The software I use is:

- mvl_5_0_0801921_demo_sys_setuplinux

- mvl_5_0_0_demo_lsp_setuplinux_02_10_00_14

- dvsdk_dm365_setuplinux_2_10_01_18

- xdctools_setuplinux_3_15_01_59

- psp_02_10_00_14

 

After I rebuilt the Linux kernel and the DVSDK software, I tried to run the demo in /opt/dvsdk/dm365. But when I loaded the modules and invoked the interface program, I got the following:

/opt/dvsdk/dm365# ./loadmodules_hd.sh

Interface Error: Failed to create display device instance

 

Any ideas what's the reason for that error?

 

Thanks in advance.

 

  • Potential reasons:

    1) by default, the interface demo assumes you have a 720p video input source (e.g. blue-ray DVD player) and 720p video display for output.  In the hardware does not detect these video input/output devices connected at the time you run the demos, it could fail.

    2) how did you configure your u-boot bootargs?  If you followed the Getting Started Guide, you should be ok.  If you have doubts, you can post your bootargs here and we can have a look...
