Hi :
I test the TMX320DM365 for h264 encode/decode demo by TI TMX320DM365 DVEVM
kit.
Running the Demos from the Command Line:
Target $ cd /opt/dvsdk/dm365
Target $ ./loadmodules_hd.sh
A issue occur as follows:
Target $ cmemk: no version for "struct_module" found: kernel tainted.
CMEMK Error: CMEM phys_start (0x85000000) overlaps kernel (0x81000000 ->
0x85c00000)
insmod: error inserting 'cmemk.ko': -1 Invalid parameters
Can anybody please let me know, what I am missing here with DVEVM kit? How to
solve this issue.
Thanks!
