I am using a XUP development board for my project. It is this one:
I want to reconfigure this board from a second board (same one). The configuration stream is stored in the DDR RAM of the second board. My problem is, that I cannot find a way to transfer the data into the flash memory of the first board. The documentation says, that there are 3 ways for configuration:1) Flash card (can't use it in this case) 2) via USB JTAG port (the second board would need an USB host port but these boards are equipped with an USB client port only) 3) via PC4 cable (no idea how this works)
Normally the solutions 2 and 3 are done with Xilinx' IMPACT software. Since I don't have this software on the second board, this seems to be a problem, because I do not know, how this software works.
I have also checked the layout of the board. I looks like the Boundary Scan pins TMS, TCK and TDO are connected to the J6 interface (GPIOs). The problem is - where is TDI? The schematics PDF only shows a FPGA_TDI connection between the FPGA and the System Ace. It does not seem to be connected to a GPIO.
Has anyone already tried to configure such a board without using a PC and IMPACT? How did you realize that?
Thanks in advance
