how to remotely use two dev kits

Hi to all! 

I have two identical dewkits (dk-dev-4sgx230n ) and I need to use them from a remote workstation at the same time. 

The devkits are both connected to a windows pc that I access by remote desktop. 

I have two problems with this configuration: 

1) windows change the USB-blaster - USB port association each boot of remote pc so I'm not able to distinguish wich devkit I'm using. There is a way to know it or to associate at each usb-blaster a mnemonic name? 

2) After firmware develop I will need to write the flash memory, but all the procedures I found for flash the devkit require to change the position of Sw2, thing that I can not do remotely ;) Any suggestion?  

 

Thanks in advance

You can program the FTDI chip in the USB-Blaster to have a unique serial number. Download the FT_PROG tool

Read the contents of the EEPROM and save it as an XML file, then edit the serial number, and re-program the EEPROM. For example, for the two kits I have I used the serial numbers S4GXDK01 and S4GXDK02. 

 

If you only have one board plugged in, then Quartus will call them both [USB-0], however, if you have both kits plugged in, then they are [USB-0] and [USB-1], and always in the same order. The other sanity check I included was to use one of the DIP switches on the board - 0 for board zero, and 1 for board 1. The downloaded design checks that its on the right board before starting :)

JTAG download has always been sufficient for my tests, so I didn't look into this, sorry.
