Hello,
I'm just starting to work with TI products, so I'm a beginner, so my question may seem a little bit stupid.
I'm working with a OMAP L138 board ( ZoomTM OMAP-L138 EVM from Logic to be accurate ), and I'm wondering which soft I should use for the GPP/DSP communications. Apparently I can use :
- DSPLink : this is what is provided with the SDK ( ti-dvsdk_omapl138-evm_4_02_00_06 ).
- SYSLink : the brand new SYSLink, which is the future of DSPLink as far as I understood.
The kernel I use is the one provided in the last PSP ( DaVinci-PSP-SDK-03.21.00.04 ), ie. Linux 2.6.37, and built with the default configuration da850_omapl138_defconfig. Right now, I tried both possibilities : I have been able to build DSPLink and run a few samples quite easily. I also gave a try to SYSLink, although it was a little bit more difficult to make it work. But in the end I could load syslink.ko and run a sample program, apparently without errors.
So now, I would think that my best option is to develop with SYSLink, because I'm working on a brand new project, and SYSLink is the brand new thing. But on the other hand, there's still a few things bothering me with SYSLink:
- According to the release note, SYSLink supports OMAP1LXX, but has not been validated on this platform.
- Moreover, when I look to the configuration file used to build SYSLink, the only platform available is OMAP-L137 ( DA830 ), there is no configuration for OMAP-L138 ( DA850 ).
I've been looking all around but I never found a definite answer, saying if SYSLink is meant to work on OMAPL138 right now or not ? And even if I could run a sample test on the OMAP L138, I'm still wondering : should I start to develop with SYSLink, but then maybe take the risk to encounter some big issues very soon and have no help to solve it ? Or should I stick with DSPLink, for more security and support ?
One last but important point : the project I'm working on involves to do a little demo in a few weeks, so I really need to be sure that the DSP/GPP communication works good before I start developing with it.
Thanks a lot for your replies,
Arnaud
