I have purchased the TSW4100 and everything is working fine. I also downloaded the FPGA (EP2C8F256C7N) firmware source code posted by Radio-Joe in another discussion. the problem is, i was unable to find some of signals in this code which are connected to the FPGA (I just compared the signals coming and going to the FPGA in board schematics and the FPGA code). if someone has the original code or just the binary file (*.jic file) to have it as a backup before making any changes in the TSW4100 firmware, it will be helpful.
Thanks in advance.
