DM355 , GPIO . EDMA trigger

Hello every one,

I am using DM355 , MV4 lsp 1.2, I have got the EDMA working using APIs from dma.c.I can manually trigger EDMA and copy GPIO INDATA register to the memory buffer.I am also able to get normal interrupt triggered on that pin but I dont know somehow my EDMA triggering not working !!

is there anything special I need to do in order to get it enable??

How can I access EDMA's register to check what is going on exactly ?

Plus I am also not able to map EDMA channels on few GPIOs without any particular reason ...

 

Please help..

thx in advance...
