Hi,
Thank you so much for your message. Oh I didn't know that the board has a build in USB blaster 2. Thanks a lot for letting me know. So that means that I take a usual USB cable, connect it to the USB Blaster 2 port and my quartus software will be able to detect it.
For now, to program my CV device, I convert my project.sof into project.rbf (raw binary file) using quartus software. Then I copy this project.rbf file into the fat partition of a micro SD card. Then I plug this MicroSD card into my CV device board. I then use uboot to program my CV device. It's a really time consuming and lengthy process because I have to remember many uboot script commands to program my CV device.
Thanks a lot again, I shall try this microUSB port to check if it is working as a USB blaster port? Thanks a lot again..
