Avalon-MM master burst transfer

[aamodini]

I am transferring data from Nios (master) to the FPGA fabric (slave) through the Avalon-MM interface. How do I set the burstcount parameter on Nios and initiate a burst transfer?

I don't see any flag/API in system.h that will help set the burst count.

Hi,

Check this document link https://faculty-web.msoe.edu/johnsontimoj/Common/FILES/n2cpu-nii5v1gen2.pdf (page 107, 108). Just need to enable the Add burstcount signal to instruction_master. Not need to set the burstcount parameter on Nios,  burst adapters will be inserted for the burst compatibility between Nios (master) to the FPGA fabric (slave).

Thanks,
