edma3 driver help!

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

 

Ok so I wasn't particular sure where to put this, but I have a few questions... And before I ask, I'll just say i'm fresh out of college and never really worked on anything like this. But because of a strange oppurnitiy I'm diving head first into this. There is quite a bit I don't know, I just started working with windows ce 6.0 this week, and just learned about the bios/edma3 driver yesterday, and have to figure out how to get it all working.

I'm using an evaluation board, OMAP-L138, with bios 6, I have LLD edma3 1.07.00.01 and 2.00.01.04. I have to get this working on both the ARM in windows CE and the DSP, and I've managed to get the drivers to compile for version 2.00.01.04 but noticed they don't have an example config file for the c6748. Also would I need a different config for the ARM, or is there a config I can use for the OMAP-L138 that will work for both?


If I can't get the config sorted out will the driver 1.07.00.01 work with bios 6?


I feel like I may have to make the config file and if that happens where do I go to start this?

 

Any help would be greatly appreciated, thanks in advance

    Hi,

    I am also working with OMAPl138 EVM board. I use the EDMA3LLD v. 02.10.02.03. There is an example with the appropriate RTSC config folder. You can download a newer version of LLD3 driver at:

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/psp/edma3_lld/index.html

    Then you just have to go to Project > Import existing eclipse project > installation path of platform OMAPL138 [C:\Program Files\Texas Instruments\edma3_lld_02_10_02_03\examples\edma3_driver\evmOMAPL138] > finish

    This should import the example and appropriate config project. Do not forget to include the installation direction of LLD3 under CCSv4 > Window> Preferences > General > Workspace > linked ressources.

    Then it should work and you can debug the example on your OMAPL138 platform.

    Hope this helps you.

    definitly

    though, i'm having a hard time porting the example, when it shows up, there are a couple of things that are off with it, mainly the src files all have ! next to them, so I'm assuming they didn't get properly linked, and I did link the folder, aslo I noticed the code gen tools were version 6 and i'm using version 7

    the other thing, porting this to visual studio 2005 for WIN CE, I'm assuming I'll have to use the same include locations,

    -D xdc_target_types__=microsoft/targets/arm/std.h

    -D -Dxdc_target_name__=WinCE

    and the omap arm configs, i'll probably just copy the example src files right into a project and try and test those...

    Never mind I realize its part of the board support package stuff now
