I downloaded the Terasic image and bootup via SDcard (after connecting the “USB-UART” USB port to the PC running Linux, and then started up “minicom -s” to connect to it via /dev/ttyUSB0.

Bootup message:

https://gist.github.com/tthtlc/4af887b22fa3a4d55f2d7c5f112f5b4a

Programming technical details of the board can be found here (as part of the uboot which loaded up the hardware):

https://github.com/ARM-software/u-boot/tree/master/board/terasic/sockit

Next I attempted to connect the “USB-Blaster” to the PC, and startup the Quartus Prime Lite (linux 64-bit) to recognize the board but ended up not recognized successfully:

But for programming wise, this link provides lots of in-depth details:

and this backlink:

Will continue researching on this.

How to use USB Blaster as FPGA/CPLD programmer

Posted by Peter Teoh in technical. Leave a comment

In general a "JTAG" port is always provided in the Intel FPGA or CPLD board for programming the FPGA device:

: image 13

And sometimes for the development board (eg, DE10 from Terasic) the USB Blaster is built into the SoCKit:

https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=167&No=1081 (see the "USB Blaster USB port" below)

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/manual/mnl_cii_starter_board_rm.pdf

The internal of the USB Blaster (user-guide level) is explained here:

And how to use Quartus to connect to the USB Blaster is here:

Commercial products available (eg, www.aliexpress.com and search for USBTinyISP):

USBTinyISP: (connect the ISP output to the ISP part of the Arduino)

And the technical details of USBTinyISP:

http://www.mouser.com/ds/2/737/usbtinyisp-706693.pdf

Software to use is just Arduino IDE itself: choose ISP and then “burn bootloader”.
