EDMA transmits just half of the values

Hi,

I´m working with the OMAPL138LCDK and try to get an edma example running on my chip. I want to transmit just 32 shorts to another array. In just can transmit half of the values. After this the callback function opens and the NULL Link erases my ParamSet. The next problem is, that my callback-function (or isr) gets not the right parameters. How can I transmit the parameters (tcc,status,appdata) to the callback-function. I defined an handle for the API ...requestchannel(...,cbData) what should I insert there. Does anyone have a clue? I tried doubling acnt, or bcnt but it didn´t work, there must be something completely different.

Yours sincerly

Christoph
