Hi, Dhut:
I got the bbxm rev c two months ago. I want to use it to achieve
the goal of tracking peopl. And owing to wanting to make most use of bbxm,
i want to use the dsp core in dm3730. According to materials i read, i want
to use the gstreamer, dmai and codec engine to develop my application.
However, i have not done davinci development before or even arm. so this
job is so hard for me, i think. so could you give me some practical
suggestion for me? if you have qq number, could you give it to me through
gmail? thank you!!!
