    Hi, I have been trying to do a library project type (.lib) for the OMAP-L138. I'm using the PSP drivers and GIO commands in the library project. My goal is develop an peripheral abstraction (PAL). But I wonder if it is possible to insert the libraries already generated (. a674) in the project...

    Hello! Thank you for your help. I really appreciate it. One last thing about the registers... Should I write to IESR[8] in "Global Channel Registers" (address 0x01C0 1060 for OMAP L-138) or to "Shadow Region 1 Channel Regiser (0x01C0 2260)? Anyway, by setting both to 8, all others...

    Hi I have my McASP output connected to the oscilloscope so I can easily verify if the transfers are happening correctly or not. Also just by examining XSTAT register of McASP I'm able to verify if it's getting the data form DMA. I followed the instructions on pages 31, 32 of http://wiki.davincidsp...

    Hi Szymon I have a few pointers. Szymon Kuklinski I'm still having some doubts about TCINTs. Here's the whole situation: EDMA Channel 1 is triggered upon TXEVT from McASP. It does some preliminary data transfer and manipulation and then triggers channel 10 that is chained...

    Hi Answering your questions...: 1) At the moment I'm only using DMA interrupts and those originating form DSPLink. The interesting thing however is that removing much of the DSPLink code doesn't seem to help. When I comment some time consuming signal processing functions that run in the...

    We recently bought a second TMDSEVLM138 OMAP-138 EVM and are unable to run the code we developed on our original OMAP-138 EVM. We are using the TMS320C6748 DSP SOM on both boards. The original EVM came with rev A of the SOM and the new EVM came with rev B of the SOM. The code crashes on the new board...

    Christian Sch���
    I'm using the Audio SOC example provided in the SDK as a template for my own application. Since I'm using quite a few large data buffers (on the DSP side), I want to place all data in L2 memory instead of external memory to increase the speed. Thus, I have added the following lines to the file...
