MW 07:46 AM FPGA Development: RE: Writing to HPS memory

I would recommend contacting your Arrow FAE or Altera for help with the device tree generation / sopcinfo file.
You will need to create a new preloader and uboot and device tree block. You may also need to rebuild the kernel with the... Michael Williamson

VG 07:39 AM FPGA Development: Writing to HPS memory

Hi,
I'm want to use the hps_ddr_write_example design from critical link and test it on Arrow Terasic Cyclone V SOCKit .
I have changed the device and the HPS DDR3 parameters in the Quartus project.Also I'm using the Arrow kit's DDR3 ... Vidya Govindan

DV 02:22 PM FPGA Development: RE: Modular SGDMA

Hi Jack,
We don't have any explicit examples of this but you will want to look into the userspace I/O driver. This should allow you to map in the FPGA interrrupts to a /dev/uio device.
I did a bit of searching and this looks like a... Daniel Vincelette

01:40 PM FPGA Development: RE: Modular SGDMA

Hi Dan,
The issue seems to be with the polling. I brought out the empty signal to an oscilloscope and found that it is on, but for some reason I'm not reading that on the software side.
I think it's better to switch to interrupt to... Anonymous
