That is how I started and was also my best bet...using the pristine and
original dvsdk_dm_3730-evm_4_00_00_17 and its 2.6.32 kernel. I simply
wanted to use the c6run stuff but it would not compile. So, as you
suggest, I asked for help on the forum... see it here:
http://e2e.ti.com/support/embedded/f/355/p/91625/318351.aspx#318351
In that posting, it was suggested to try a newer version of c6run and a
completely new dvsdk version (I tried 4_01_00_09 and it had issues
also).
I can spend a little more time to repeat what I have already tried since
nobody has pointed out anything obvious. I had asked and hoped for a
very detailed and complete steps for downloading, configuring and
compiling a new kernel (I need features from 2.6.38 kernel) and c6run
tools and/or new dvdsdk, and getting the DSP examples to work. I asked
for this so I don't simply repeat the same mistakes again.
After I get the DSP working on the TI dev board, then I can try to get
the DSP to work on my Overo Fire, which seems more vague and difficult.
