DMA Size

Postby JohnT » Wed Mar 21, 2018 10:47 pm

Hi,

I am using embedded linux kernel 3.10.40 and we are dealing on data overflow in stream.
I would like to know if it's possible to change the size of the DMA via the xillybus driver?. If yes, can I have some info on how to do it?.

Regards,

John

Hello,

In order to change the size of the DMA buffering between the FPGA and the host, a custom IP core should be generated at the Custom IP Core Factory (on the website).

There is no possibility to change this attribute from the host.
