Hello friends,
I'm trying to run the video demos on my DM814x using 1 DDR of 256MB,
I'm using DVRRDK_04.01.00.02 and was successful in running the demos with 512MB.
I'm able to load the M3s but when I try to insmod my vpss.ko I get:
VPSS_FVID2: contrl event 0x10080002 timeout
VPSS_SYSTEM: failed to get platform id
my memory map is as follows:
