Hi, all. I have problems when running dvsdk-demos in BBXM. First of all, based on what the website(sourceforge.net/.../) says, I have the dvsdk of beagleboard-xm. After I boot, I came cross the problem like this.
root@beagleboard-dvsdk:/usr/share/ti/dvsdk-demos# ./encode -o
Encode demo started.
Failed to open /sys/devices/platform/omapdss/display2/enabled for writing.
However there is no …/display2 direction in the filesystem. Should I rectify the uboot parameters in uEnv.txt? And another question is whether the encode demo can capture images via usb webcam or not?
Or like follows:
root@beagleboard-dvsdk:/usr/share/ti/dvsdk-demos# ./decode -v HistoryOfTI-480p.2
64 -O dvi
Decode demo started.

BUT there were no images or video in the screen.
So this problem has bored me for a long time. Could someone give me some advice? Thanks a lot.
Another question: in which file the memory map in dm3730 is set ? how can i look for or rectify the memory map?
