DMA FIFO from FPGA to RTOS on sbRIO

[Al1234]

I have a sbRIO-9631 it's working fine with the FPGA sending data to the laptop host VI using a DMA FIFO.

I have just moved the laptop VI to my RTOS and at this point the FIFO stops working. The rest of the program works OK. Before I dive into low-level debugging is it actually possible to have a FIFO from FPGA to RTOS?.

I remember reading something about this but can't find it in the help or manuals.

Hi,

You can have a FIFO on the RTOS from the FPGA (Target to Host), it may be that the FIFO is filling or reaching a timeout condition on the Host read.

Kind Regards,
