Hi,

 

I want to do dma transfers between PCi device and RAM in my T2080RDB. I have created a device driver but it does not work properly. It looks like it is not allow to write in the address that  I give to it .

 

I am wondering if I have to change something in the dbt or in the PCI configuration registers in my T2080rdb.

 

Any idea?

 

BR.
