Hi JColvin, sorry, my bad. I was trying to program the FPGA under Linux without Vivado using openocd-0.11. At first I succeeded two times using "sudo openocd ...", then I changed the jumper, changed the command and continued without sudo. So the program didn't find the board anymore and I thought something would be damaged. In fact openocd was missing the rights to access the USB. Then I tried with my Windows Vivado installation. It didn't recognize the board. Then I transferred the EEPROM Contents of a second Arty S7-50 board to my first board with an old installation of FT_Prog_v3.6.88.402. Later I found out my Windows Vivado doesn't recognize any Boards. On a second Windows PC our second board is recognized fine, while the first board now isn't recognized by any Vivado any more. And I found I still can program the first board using "sudo openocd ..." under Linux. So what's the missing magic to make my board appear as a programmer in Vivado again?

Hi @JColvin, I have an ArtyS7-50 Board with the FT2232 chip on it. After changing the JP1 jumper position while the board was running it now isn't recognized by Vivado any more. The FPGA itself still works fine from SPI flash. Would you please provide me with instructions, how reprogram the EEPROM of the FTDI? Best regards, Christan
