Hi AsValdr,
Exactly the same as me, the sgdma wait for receive the descriptor chain.
Are you using SOPC or QSYS ?
I don't know why there is a problem with the descriptor.
Maybe a problem with the connnection with the on-chip memory of the descriptor ?
Can you tell me if you it works if you re-add the sram controller like the original project ?
I don't If there is some people from Altera in this forum ?
Maybe some other developpers can test the same thing and tell us if it work or not ?
Thanks.
ps: I debug the sgdma and see that the descriptor chain is not receiv.
